Answer:
Step-by-step explanation:
2x3/5+1/5
Going by BoDMAS
Multiplication comes before addition
2x3/5+1/5 = 6/5 + 1/5 = (6+1)/5
= 7/5 = 1 2/5
Final answer:
The expression 2x3/5+1/5 is solved by first multiplying 2 by 3/5 to get 6/5 or 1.2, and then adding this to 1/5 to get the final answer of 7/5 or 1.4.
Explanation:
To solve the expression 2x3/5+1/5, you first need to perform the multiplication before the addition, according to the order of operations (PEMDAS/BODMAS). So, you need to multiply 2 by 3/5:
2 x 3/5 = 6/5 or 1.2
Now add this result to 1/5:
6/5 + 1/5 = 7/5 or 1.4
Therefore, the answer is 7/5 or 1.4.

Jackie says that the fraction 7/8 is equivalent to 3/4. Is she right? Explain
Answer:
Jackie is incorrect.
Step-by-step explanation:
[tex]\frac{3}{4}[/tex] [tex]\left {x2} \atop {x2}} \right.[/tex] = [tex]\frac{6}{8}[/tex]
[tex]\frac{3}{4}[/tex] is equivalent to [tex]\frac{6}{8}[/tex] not [tex]\frac{7}{8}[/tex]
Jackie is mistaken when she claims that the fraction 7/8 is equal to 3/4. We compare the numerator (the top number) and denominator (the bottom number) of two fractions to see if they are equal.
In this instance, 3/4 has a denominator of 3 and a numerator of 4, whereas 7/8 has a numerator of 7 and a denominator of 8, respectively. The fractions cannot be equal since the numerators and denominators vary.
Two fractions must have the same numerator to denominator ratio in order for them to be equal. In this situation, 7/8 is a bigger fraction than 3/4. Jackie's assertion that 7/8 is comparable to 3/4 is therefore false.

Which absolute value expression represents the distance between 3 and - 2 on a number line?
Answer:
|3 - (-2) |, or|-2 - 3|Both are equivalent.
Explanation:
The distance between two numbers in a number line is the absolute value of the difference between the two numbers.
Thus, the distance between a number x and a number y is |x - y|, which is also equivalent to |y - x|.
In this case the distance between 3 and - 2 can be represented by either of the expressions:
|3 - (-2) |, or|-2 - 3|Note that when you simplify them you get the same value:
|3 - (-2) | = |3 + 2| = |5| = 5|-2 - 3| = | -5| = 5Answer:

Pacho starts saving for college by opening a savings account and depositing $50. He plans to make a deposit every month to continue saving. The amount of money in Pacho's savings account can be modeled by the sequence A0=50, An=An−1 + 25, where n is the number of months since his initial deposit. Is the sequence An a function? Why or why not?
The sequence is a function
Step-by-step explanation:
The sequence is given as;
[tex]A_n=A_n-1 +25[/tex]
where n is the number of months since his initial deposits, and A₀=50
The sequence is a function because its domain is a set of natural numbers.

A₂=A₁+25=100
A₃=A₂+25=125

find one terminating decimal and one repeating decimal between -1 1/2 and -1 7/9
Answer:
-1.777...
Step-by-step explanation:
Using the LCM of 18 for the denominator, these values are:
-1 7/9 -1 1/2
-32/18 -27/18 0
--------------|-------------------|-------------------------------------|-----------
So, the easy values to identify are: -31/18, -30/18, -29/18, and -28/18
All of these numbers have repeating decimals (because 9 is a factor of the denominator).
Now, you may realize that -1 3/4 is within the range specified.
-1 7/9 -1 1/2
-32/18 -27/18 0
--------------|-------------------|-------------------------------------|-----------
|
-1 3/4
-1.75
This is because -1.75 is between -1.5 and -1.7777.... Note that it is not repeating.

What is the fraction
Answer: 2 1/6
Step-by-step explanation:
Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.
4 1/2 -> 9/2
6 2/3 -> 20/3
Next, make the denominators the same by multiplying each fraction by the denominator of the other.
9/2 * 3 = 27/6
20/3 * 2 = 40/6
Then you can subtract the numerators because the denominators are the same:
40/6-27/6= 13/6
Then you can convert to a mixed fraction if need be.
write and solve the differential equation that models the following statment. "the rate if change of W with respect to x is proportional to x+18."
Answer:
[tex]\int k(x + 18)dx = \int kx + 18k dx[/tex] = [tex]k\frac{x^{2} }{2}[/tex] + [tex]18kx[/tex] + C where C is the constant of integration.
Step-by-step explanation:
i)it is given that the rate of change of W with respect to x is proportional to
x + 18. Therefore [tex]\frac{dW}{dx}[/tex] = k(x + 18) where k is a constant.
ii) Therefore [tex]\int k(x + 18)dx = \int kx + 18k dx[/tex] = [tex]k\frac{x^{2} }{2}[/tex] + [tex]18kx[/tex] + C where C is the constant of integration.
iii) the complete solution can only be found if we know the constant of proportion and also the constant of integration.
Need help with question number 13. Can’t figure it out.
Answer:
least common multiple
Step-by-step explanation:
Find the lcm of the given numbers, do you know how to do that?
Alright, so you're looking for the GCF.
Greatest Common Factor
I don't wanna go into detail of what that is (if you don't already know what it is, please watch a video on what it is and how to find it.)
Our numbers are 18, 36, 54
What is the gcf of these numbers? They all are both divisble by 18 and that's the largest 18 can go, so 18 is the GCF.
18 is the answer.
x/3 = 14 whats the answer
Answer: x = 42
Step-by-step explanation:
Step 1 :
x
Simplify —
3
Equation at the end of step 1 :
x
— - 14 = 0
3
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 3 as the denominator :
14 14 • 3
14 = —— = ——————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (14 • 3) x - 42
———————————— = ——————
3 3
Equation at the end of step 2 :
x - 42
—————— = 0
3
Step 3 :
When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-42
———— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-42 = 0
Solving a Single Variable Equation :
3.2 Solve : x-42 = 0
Add 42 to both sides of the equation :
x = 42
Your answer: x = 42
Answer:
42
Step-by-step explanation:
x / 3 = 14.
The question required you to solve for x.
First, multiply both the LHS and the RHS by 3. The aim is to make x independent.
x/3 * 3 = 14 * 3
Therefore:
x = 42

What is the perimeter of 10 ft long and 9 feet wide?
Answer: Answer is 38ft.
Step-by-step explanation: The figure that measures 10ft by 9ft is a rectangle which means two sides measure 10ft each (length) and two sides measure 9ft each (width). A perimeter simply measures all sides of the entire shape, that is;
10ft + 9ft + 10ft + 9ft = 38ft.
Bob bought 24 hockey tickets for $83. Adult tickets cost $5.50 and child tickets cost $2.00. How many child tickets did he buy?
Answer:
Step-by-step explanation:
a + c = 24......a = 24 - c
5.5a + 2c = 83
5.5(24 - c) + 2c = 83
132 - 5.5c + 2c = 83
-5.5c + 2c = 83 - 132
-3.5c = - 49
c = -49 / -3.5
c = 14 <==== 14 child tickets
a + c = 24
a + 14 = 24
a = 24 - 14
a = 10 ........and 10 adult tickets
|6 3/8-2|+|-8 5/8+(-1)|
To answer the question, we evaluated two absolute value expressions individually by converting mixed numbers to improper fractions, performing the operations, and taking absolute values. The sum of these evaluations is 14.
The question involves evaluating two absolute value expressions and adding the results. We will work through each expression step by step.
First Expression
|6 3/8 - 2|
To solve this, convert the mixed number to an improper fraction, subtract 2, and then find the absolute value.
Convert 6 3/8 to an improper fraction: (6 × 8) + 3 = 51/8.
Subtract 2 (written as 16/8) from 51/8: 51/8 - 16/8 = 35/8.
The absolute value of 35/8 is 35/8, as it is already positive.
Second Expression
|-8 5/8 + (-1)|
Similar approach: convert to an improper fraction, add -1, and find the absolute value.
Convert -8 5/8 to an improper fraction: (-8 × 8) - 5 = -69/8.
Add -1 (written as -8/8) to -69/8: -69/8 - 8/8 = -77/8.
The absolute value of -77/8 is 77/8, as we discard the negative sign in absolute value operations.
Add the results of both expressions: 35/8 + 77/8 = 112/8 = 14.
