stich3 [128]

Answer:

You can buy 7 waffle cones.

Step-by-step explanation:

Let sundae = x

Let waffle cones = y

4.25x + 3.75y ≤ 50

4.25 (5) + 3.75y ≤ 50

21.25 + 3.75y ≤ 50

3.75y ≤ 28.75

y ≤ 7.666666666

* round to the nearest whole to get 7

Yanka [14]

Answer:

<em>Mechanic A worked for 5 hours</em> and <em>Mechanic B worked for 15 hours</em>

I hope my answer and explanation helped!

<u>okay to get started you need to make a system of equations:</u>

x= number of hours worked by mechanic A

y= number of hours worked by mechanic B

x + y= 20

95x + 60y= 1375

<u>substitute in an equation:</u>

x + y= 20

y= 20- x

95x + 60(20-x)=1375

<u>Solve for x</u>

95x + 1200 - 60x=1375

35x =175

x= 5

<u>plug in x to solve for y</u>

x + y= 20

5 + y= 20

y=15

<u>Check work</u>

then you're done :D

Number 17.
agasfer [191]

2x + By = 15

We solve for y to put the equationj in the y = mx + b form in which b is the y-intercept.

By = -2x + 15

y = -2/Bx + 15/B

The y-intercept is 15/B, and we are told the y-intercept is 5.

15/B = 5

15 = 5B

B = 3

Answer: E. 3
