Answer:

x = 3 / y = 6

Step-by-step explanation:

5x - 2y = 3

-5x + 4y = 9

-----------------   (combine the equations)

2y = 12

isolate the variable

y = 6

next, use one of the original equations and substitute in for y to solve for x

5x - 2(6) = 3

multiply

5x - 12 = 3

isolate the variable

5x = 15

divide each side by 5

x = 3

Marina CMI [18]

Answer:

Step-by-step explanation:

A = B+4

D = 2A

B = 2C

D-C =  38

2A - B/2 = 38

2(B+4) - B/2 = 38

4B+16 - B = 79

3B = 63

B = 21

A = B+4 = 25

Arionna claims that since there are 3 feet in a yard, there are 9 cubic feet in a cubic yard. Which statement about her claim is
Vera_Pavlovna [14]

Answer:

  d.)  Arionna is incorrect. There are 27 cubic feet in a cubic yard because a cubic yard is a prism with dimensions 3 ft times 3 ft times 3 ft. A prism with those dimensions will take 27 cubes to fill it, if each cube is a unit cube of 1 ft³.

Step-by-step explanation:

There are (3 ft)(3 ft) = 9 ft² in one square yard. To find the volume of a cubic yard, you need to multiply that by 3 ft again: (9 ft²)(3 ft) = 27 ft³.

_____

<em>Additional comment</em>

For many problems involving units, I like to keep the units with the numbers. That helps ensure the math is done correctly. In this problem, simply multiplying ft by ft gives ft^2, not ft^3, so you know right away that you haven't computed volume correctly.
