You need to use a system of equations with 2 variables
where x= # of paintbrushes bought
and y= # of paint units bought

the first equation would be
.95x+.99y=4.87

Usually there is more information given in these problems so that you can make the second equation. Did the problem say how many total items were bought or anything else because given this information you cannot make a second equation and therefore cannot solve for both variables. Also, the wording is unclear, did she spend 4.87 on just paintbrushes or both brushes and paint.

She bought 2 paintbrushes and 3 paints. because if 5 multiplied by anything the result will only 5 or 0. but to get 7 you need to multiply 9 by 3

Determine if there is a proportional relationship between the two quantities. Explain your reasoning.
Zinaida [17]

Step-by-step explanation:

If two quantities A and B are proportional, then:

B = kA

where k is a constant.

We can check if these are proportional by seeing if the ratio between A and B is the same at each point:

B/A = k

92/35 = 2.629

80/23 = 3.478

The ratios aren't the same, the relationship is not proportional.

What is the circumference of the circle? (use 3.14 for pi )
ArbitrLikvidat [17]

Answer:

This is the complete question;

What is the circumference of the circle?  shown in the image

(use 3.14 for pi )

A 18.84.98 cm

B. 36 cm

C. 37.68 cm

D. 37.7 cm

<em>The circumference of the circle would be "C" 37.68 cm</em>

Step-by-step explanation:

The circumference of a circle is the distance around or right around the circle. The circumference of the circle is also the perimeter of the circle.

<h3>Calculating the Circumference of the Circle.</h3>

The circumference of the circle can be obtained using the relationship below;

C = πd

Where C is the circumference and its unknown

d is the diameter of the circle = 12 cm

π is a constant = 3.14

C = 3.14 x 12

C = 37.68 cm

Therefore the circumference of the circle would be 37.68 cm

-2 (2x + 11) = 5x + 14
amid [387]

Answer:

x=-4

Step-by-step explanation:

First, write the expression and distribute.

-2(2x+11)=5x+14

-4x-22=5x+14

Add one of the variables to the other side (it makes solving a lot easier). I'll add 4x to both sides because it won't result in a negative x.

-4x-22=5x+14

<u>+4x      +4x</u>

-22=9x+14

Now, subtract 14 on both sides.

-22=9x+14

<u>-14        -14</u>

-36=9x

Divide both sides by 9.

-36=9x

<u>/9   /9</u>

-4=x  or  x=-4 (they both mean the same thing)

Have a wonderful day! I hope this helped :3
