1. We have to get the sum as follows :
[tex]3\frac{4}{9} + 4\frac{6}{9}[/tex]
= [tex]\frac{31}{9} + \frac{42}{9}[/tex]
= [tex]\frac{31 + 42}{9}[/tex]
= [tex]\frac{73}{9}[/tex]
= [tex]8\frac{1}{9} \neq 7\frac{1}{9}[/tex]
So, this is false.
2. We have to get the sum as follows :
[tex]4\frac{5}{6} + 1\frac{3}{6}[/tex]
= [tex]\frac{29}{6} + \frac{9}{6}[/tex]
= [tex]\frac{29 + 9}{6}[/tex]
= [tex]\frac{38}{6}[/tex]
= [tex]6\frac{2}{6}[/tex]
So, this is true.
3. We have to get the difference as follows :
[tex]4\frac{5}{8} - 2\frac{4}{8}[/tex]
= [tex]\frac{37}{8} - \frac{20}{8}[/tex]
= [tex]\frac{37 - 20}{8}[/tex]
= [tex]\frac{17}{8}[/tex]
= [tex]2\frac{1}{8} \neq 2\frac{3}{8}[/tex]
So, this is false.
4. We have to get the difference as follows :
[tex]7\frac{5}{8} - 4\frac{2}{8}[/tex]
= [tex]\frac{61}{8} - \frac{34}{8}[/tex]
= [tex]\frac{61 - 34}{8}[/tex]
= [tex]\frac{27}{8}[/tex]
= [tex]3\frac{3}{8} \neq 3[/tex]
So, this is also false. (Answer)

A. 3.4.
B. 0
C. 21/68.
D. 4.25
====================================
Work Shown:
x - 3.4 > 17/68
x - 3.4 > 0.25
x - 3.4 + 3.4 > 0.25 + 3.4 .... add 3.4 to both sides
x > 3.65
Any number larger than 3.65 will work in place of x

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.
Kimberly is using ribbon to create girls' hair barrettes. For a craft fair in Rockport, she made 13 small barrettes and 11 large barrettes, using a total of 142 yards of ribbon. Then, for another craft fair in Westminster, she made 13 small barrettes and 12 large barrettes, which used a total of 149 yards. How many yards of ribbon does Kimberly use for each?
Answer:
Step-by-step explanation:
x = small barrettes
y = large barrettes
13x + 11y = 142.......multiply by -1
13x + 12y = 149
-----------------------
-13x - 11y = -142 (result of multiplying by -1)
13x + 12y = 149
------------------------add
y = 7..........large barrettes used 7 yards
13x + 11y = 142
13x + 11(7) = 142
13x + 77 = 142
13x = 142 - 77
13x = 65
x = 65/13
x = 5........small barrettes used 5 yards
Final answer:
Kimberly uses 5 yards of ribbon for each small barrette and 7 yards of ribbon for each large barrette. The problem was solved using a system of equations and the elimination method.
Explanation:
To solve the problem using a system of equations and the elimination method, we first need to define variables for the unknown quantities we are trying to find. Let's let x represent the number of yards of ribbon used for each small barrette and y represent the number of yards of ribbon used for each large barrette.
From the information given, we can set up the following system of equations representing the two craft fairs:
For Rockport: 13x + 11y = 142
For Westminster: 13x + 12y = 149
Now, we will solve these equations using the elimination method. To eliminate one of the variables, we can subtract the first equation from the second equation.
13x + 12y - (13x + 11y) = 149 - 142This simplifies to:
y = 7
Using the value of y, we can substitute it back into either equation to find x. Plugging it into the first equation:
13x + 11(7) = 142
13x + 77 = 142
13x = 142 - 77
13x = 65
x = 65 / 13
x = 5
Therefore, Kimberly uses 5 yards of ribbon for each small barrette and 7 yards of ribbon for each large barrette.

5. Chris pays a fee if her bank balance falls below $10 on the statement
date. Prior to the statement date, her balance was -$3.46. Then, Chris made a deposit, d, in ample time, so she did not have to pay a fee.
a. Write an inequality to represent this situation.
Answer:
d ≥ 13.46
Step-by-step explanation:
Chris has to pay low balance fee if her bank balance falls below $10.
Her balance was -$3.46 before the statement date.
Now, Chris has to deposit a minimum amount of $(3.46 + 10) = $13.46 to her bank account and then only she does not need to pay a fee.
If the deposit amount is d, then the inequality to represent the situation is
d ≥ 13.46 (Answer)
Final answer:
Chris needs to deposit at least $13.46 to prevent a bank fee because her balance was -$3.46. By adding $3.46 to the minimum required balance of $10, we determine the least deposit amount through the inequality d ≥ 13.46.
Explanation:
To solve the situation where Chris avoids a fee by making a deposit, d, we must write an inequality that reflects her balance being above $10 after the deposit. Originally, her balance was -$3.46. Therefore, after deposit d, her new balance must be equal to or greater than $10 to prevent the fee. The inequality representing this situation is:
d - 3.46 ≥ 10
When you add $3.46 to both sides to isolate d, the inequality becomes:
d ≥ 13.46
This inequality indicates that Chris's deposit must be at least $13.46 to avoid the bank fee.

What is the equation of a circle with center (-7, -3) and radius 2?
Answer:
B = (x + 7)^2 + (y +3)^2 = 4
Step-by-step explanation:
The equation of a circle with center (-7, -3) and radius 2 is (x + 7)² + (y + 3)² = 4.
Explanation:The equation of a circle with a center at point (-7, -3) and a radius of 2 can be written based on the standard form of the circle equation (x - h)² + (y - k)² = r², where (h,k) is the center of the circle and r is the radius.
Plugging in the values given in the question, the equation simplifies to: (x + 7)² + (y + 3)² = 4.

A jet plane traveling at 550 mph overtakes a propeller plane traveling at 150 mph that had a 3-hour head start. How far from the starting point are the planes?
The planes are 618.75 miles from starting point
Solution:
Let t is the travel time of the jet
Then (t + 3) is the travel time of the propellar
When the jet overtakes the propellar, they will traveled the same distance
Distance is given as:
[tex]Distance = speed \times time[/tex]
Distance equation for JetA jet plane traveling at 550 mph
[tex]Distance\ by\ jet = 550 \times t\\\\Distance\ by\ jet = 550t[/tex]
Distance equation for propellar:propeller plane traveling at 150 mph
[tex]Distance\ by\ propellar = 150 \times (t+3)[/tex]
Equate both distance
[tex]550t = 150(t+3)\\\\550t = 150t + 450\\\\550t - 150t = 450\\\\400t = 450\\\\t = \frac{450}{400}\\\\t = 1.125[/tex]
Find the distance from the starting point[tex]Distance = 550 \times t = 550 \times 1.125\\\\Distance = 618.75[/tex]
Thus they are 618.75 miles from starting point
The distance both planes are from the starting point when the jet overtakes the propeller is 451.125 miles.
Explanation:This question is a math problem involving relative speed and distance traveled. In this case, we are solving for the distance each plane has flown from their respective starting points once the jet plane overtakes the propeller plane.
To start, let's think of the problem in terms of a timeframe. We know the propeller plane had a 3-hour head start. Now, we need to determine how long it took for the jet plane to catch up to the propeller plane. To calculate this, we must find the difference in speed between the two planes (550 mph - 150 mph = 400 mph), and then divide the time difference (3 hours) by the relative speed (400 mph) which equals 0.0075 hours.
Next, we compute the distance covered by the propeller plane in 3.0075 hours (150 mpg * 3.0075 hours = 451.125 miles). Both planes are at this same distance from the starting point when the jet plane overtakes the propeller plane.

The longest side of the triangle section is 4 feet shorter than twice the shortest side. The third side is 3 feet longer than the shortest side. The perimeter is 59 feet . How long is each side
===========================================
Define the three sides to be a,b,c such that a < b < c
So c is the longest side, and 'a' is the shortest with b in the middle.
"longest side is 4 ft shorter than twice the shortest side" means that c = 2a-4
"third side is 3 ft longer than the shortest side" so b = a+3
Both b and c are in terms of 'a', allowing us to do substitutions like so
a+b+c = perimeter
a+b+c = 59
a+(a+3)+c = 59 .... first substitution, plug in b = a+3
a+(a+3)+(2a-4) = 59 ... second substitution, plug in c = 2a-4
4a-1 = 59 .... combine like terms
4a = 59+1 ... add 1 to both sides
4a = 60
a = 60/4 ... divide both sides by 4
a = 15
The shortest side is 15 ft
b = a+3 = 15+3 = 18
The middle side is 18 ft
c = 2a-4 = 2*15-4 = 26
The longest side is 26 ft
---------------------
Check:
The three sides should add up to a perimeter of 59 ft
a+b+c = 15+18+26 = 59
so the answer is confirmed
Answer:
[tex]Leg_1 = 15\\Leg_2 = 26\\Leg_3 = 18[/tex]
Step-by-step explanation:
Form an equation.
[tex](x)+(2x-4)+(x+3)=59[/tex]

the subtraction property of equality
B.
the multiplication property of equality
C.
the division property of equality
D.
the addition property of equality
Answer:
D.
the addition property of equality
Step-by-step explanation:
Given the expression in
Step 2: 9d - 5 = -15
The addition property of equality was used to get step 3.
That is
9d - 5 = -15
Move -5 over the equality sign and it becomes +5
9d = -15 + 5
9d = -10
OR add 5 to both sides of the equation as shown below
9d - 5 +5 = -15 + 5
9d = -10 which we have in step 3
The justification for step 3 is the subtraction property of equality, which allows us to subtract the same number from both sides of an equation to maintain its balance.
Explanation:The correct answer is A: the subtraction property of equality.
Here is why: In the step before (step 2), we have 9d - 5 = -15. When we move to step 3, we're solving 9d = -10 which means we added 5 to both sides of the equation. By doing so, we subtract 5 from the left side to get 9d and add 5 to -15 on the right side to get -10. This action is consistent with the subtraction property of equality, which states that you can subtract the same number from both sides of an equation and the equation will still hold true.

x= -y + 6
The solution is x = 2 and y = 4
Solution:
Given system of equations are:
y = 2x -------- eqn 1
x = -y + 6 ----------- eqn 2
We can solve the system of equations by substitution method
Substitute eqn 1 in eqn 2
x = -2x + 6
Move the variables to one side and constants to other side
x + 2x = 6
3x = 6
Divide both sides of equation by 3
x = 2
Substitute x = 2 in eqn 1
y = 2(2)
y = 4
Thus the solution is x = 2 and y = 4
