Brad has $1.65. He spends 75 cents to buy a card. How much change does he get back ?
Answers
Final answer:
After purchasing a card for 75 cents, Brad receives 90 cents back in change from his initial $1.65.
Explanation:
The student's question is about calculating change returned after a purchase, which is a basic arithmetic problem. Brad starts with $1.65 and spends 75 cents on a card. To find out how much change Brad gets back, we subtract the cost of the card from the amount Brad started with.
$1.65 - $0.75 = $0.90
Therefore, Brad gets 90 cents back in change after buying the card.

Tracy needs to find the length and width of the equipment storage room where she works. The room is 3 meters longer than it is wide. Its perimeter is 18 meters. Find the width in meters
Answers
If the length is 3m longer than the width, you can write the width as x and the length as x + 3. The perimeter would be both lengths and both widths added together, so you would just write it as:
x + x + x + 3 + x + 3 = 18
4x + 6 = 18
- 6
4x = 12

Cookies are on sale! Today each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost you $2.80! Write an equation to determine the normal price of each cookie. Find the normal price of each cookie.
Answers
(C - $.75) 7 = $2.80
Divide both sides of equation by 7
C - $.75 = $2.80 / 7 Add $.75 to both sides of equation
C = $.40 + $.75
C = $1.15
Answer:
The price of each cookie is $ 1.15.
Step-by-step explanation:
Let x be the normal price of each cookie,
Since, each cookie costs $0.75 less than the normal price,
Thus, the new price of each cookie = ( x - 0.75 ) dollars,
So, the price of 7 cookies = 7( x-0.75 ) dollars
According to the question,
The price of 7 cookies = $ 2.80
⇒ 7( x-0.75 ) = 2.80
Which is the required equation to determine the normal price of each cookies,
For solving the above equation,
Divides both sides by 7,
x - 0.75 = 0.4
Adding 0.75 on both sides,
x = 1.15
Hence, the price of each cookie is $ 1.15.

find the slope of a line parallel to 3x+5y=15
Answers
Answer:
A. [tex]-\frac{3}{5}[/tex].
Step-by-step explanation:
We have been given equation of a line [tex]3x+5y=15[/tex]. We are asked to find the slope of a parallel line to our given line.
We know that slopes of parallel lines are equal, so slope of the parallel line will be equal to slope of our given line.
To find the slope of our given line, we will convert our given equation in slope-intercept form of equation [tex]y=mx+b[/tex], where m represents slope of line.
First of all, we will subtract 3x from both sides of our given equation as:
[tex]3x-3x+5y=15-3x[/tex]
[tex]5y=-3x+15[/tex]
Now, we will divide both sides by 5.
[tex]\frac{5y}{5}=\frac{-3x+15}{5}[/tex]
[tex]y=\frac{-3x}{5}+\frac{15}{5}[/tex]
[tex]y=-\frac{3x}{5}+3[/tex]
Upon comparing our equation with slope-intercept form, we can see that [tex]m=-\frac{3}{5}[/tex] and option A is the correct choice.

Thus, the sum of the measures of this exterior angle, and the 2 opposing interior angles is not 180°.
It is the sum of the measure of its supplementary angle, and the other 2 opposing interior angles, which is equal to 180°.
So first, we find the measure of the supplementary angle (which is the third interior angle):
180°-(2x-12)°=180°-(2x)°+12°=192°-(2x)°.
Second, the sum of the measures of the interior angles is 180°, so:
192°-(2x)°+30°+x°=180°
192°-180°+30°=(2x)°-x°
42°=x°
So, x=42.
The measure of the exterior angle is thus:
(2x-12)°=(2*42-12)°=(84-12)°=72°

In her work, Maya misidentified the associative property as the identity property in step 2 and the commutative property in step 4.
Explanation:The question pertains to the simplification of the given expression: (5.2 − 4.5) − 5.5 + 4.8. The error lies in Maya's interpretation of the mathematical properties used in the simplification process. In Step 2, she has referred to the rearrangement of minus signs as the result of the 'identity property'. However, this should be the 'associative property' which allows the grouping of numbers to be changed. In Step 4, she refers to her re-ordering of the addition and subtraction as the 'commutative property'. However, it should be 'associative property' as it allows changing of grouping but the order within groups must be maintained.

Trygg has 3/4 package of marigold seeds. He plants 1/6 of those seeds in his garden as and divides the rest equally into 10 flower pots. What fractionof a package of seeds is planted in each flowerpot?
Answers
3/4 * 1/6 = 1/8
He divides the rest equally into 10 flowerpots. What is the rest? In order to know what "the rest" is, you must subtract 1/8 from 3/4. Find the common denominator of 4 and 8 which is 8. Multiple the numerator 3 * 2= 6 with a denominator of 8.
3/4 - 1/8 = 6/8 -1/8
= 5/8
5/8 is left to be divided equally into 10 flowerpots.
5/8 ÷ 10/1
= 5/8 * 1/10
= 5/80
= 1/16
We are required to find the fraction of a package of seeds is planted in each flowerpot.
The fraction of a package of seeds planted in each flowerpot is 7/120
Given:
Total package of seed = 3/4
Quantity of seeds planted in his garden = 1/6
Quantity of seed remaining = Total package of seed - Quantity of seeds planted in his garden
= 3/4 - 1/6
= (18 - 4) /24
= 14 / 24
Quantity of seed remaining = 7 / 12
Number of flowerpots = 10fractionof a package of seeds is planted in each flowerpot = Quantity of seed remaining ÷ Number of flowerpots
= 7/12 ÷ 10/1
= 7/12 × 1/10
= (7 × 1) / (12 × 10)

Which graph represents the solution set of the system of inequalities?

God bless!
The common shaded region of the given inequality is given by figure 3 with yellow color.
What is an inequality and how to graph it ?An inequality is a statement that compares two expressions we can solve an inequality by adding same number to both sides or by subtracting same number from both side.
To graph the inequality
Replace the sign of the inequality with equal to sign.Graph the equation made with equal to line.If the point (x, y) satisfies the inequality then check whether the inequality is satisfied on that point or not.Shade the region on that side of line where any point satisfies the equation if not shade the opposite side of region.if the sign of inequality is < ,> with equal to gin then make the line dotted for respective equality otherwise a solid line.Given inequalities are :
y < -3x -2
y ≤ x-2
For y < -3x-2 consider the equality y = -3x -2
Put x =0 ⇒ y = -2 , ( 0, -2)
Put y = 0 , x = -2/3, ( -2/3 , 0)
∴ y = -3x -2 is the line passing through the points ( 0, -2) and ( -2/3 , 0)
⇒ Put (0,0) in y<-3x-2 ⇒ 0 < -3(0) -2 ⇒0 < -2 which is false
Therefore , the inequality y<-3x-2 is the shaded region shown in figure 1
Similarly for inequality y ≤ x - 2 , Consider y = x - 2
Put x = 0 ⇒ y =-2, (0,-2)
Put y=0 ⇒ x =2 , (2,0), thus y = x - 2 is the line passing through (2,0) and (0,-2)
Put (0,0) in y ≤ x - 2⇒ 0 ≤ -2 , which is false
therefore the region of this inequality is as shown in figure 2.
The common shaded area is given by yellow color figure 3 .
