Answer:

Part 1) Michael earned walking dogs $45

Part 2) Michael earned all together $87

Step-by-step explanation:

Part 1) How much money did Michael earn walking dogs?

Let

x ----> money earned mowing lawns

y ---> money earned washing windows

z ---> money earned walking dogs      

we know that

x=$27

y=x-12-----------> y=27-12=$15

z=3y ---> z=3*15=$45

Part 2) How much did earn all together?

Adds the amount that Michael earned mowing lawns plus the amount that earned washing windows plus the amount that earned walking dogs

so

x+y+z

x+y+z=27+15+45=$87

The solid surface area is equal to the solid volume. Find the value of x? The measurements of the rectangular prism is 9 inches
Fudgin [204]

Answer:

x=7.2

Step-by-step explanation:

Let x represent height of the prism.

We know that volume of rectangular is equal to product of its height, width and length.

\text{Surface area of rectangular prism}=2(wl+lh+hw), where w, h and l represents width, length and height respectively.

We have been given that the surface area of rectangular prism is equal to the volume of the prism. So we can set an equation as:

lwh=2(wl+lh+hw)

We are also told that the measurements of the rectangular prism is 9 inches long and 4 inches wide. Upon substituting these values in above equation, we will get:

9\cdot 4\cdot x=2(4\cdot  9+9\cdot x+x\cdot 4)

Let us solve for x.

36x=2(36+9x+4x)  

36x=2(36+13x)

36x=2(36+13x)

36x=72+26x

36x-26x=72+26x-26x

10x=72

x=\frac{72}{10}\\\\x=7.2

Therefore, the value of x is 7.2 inches.
