Answer:

x=1, y= -1

Step-by-step explanation:

x = 2y +3

3x -y = 4

Use the substitution method because we have x= something in terms of y

3 (2y+3) -y = 4

6y + 9 -y = 4 subtract 9 from both sides

6y -y = 4-9 combine like terms

5y = -5 divide both sides by 5

y = -1

x= 2*(-1) +3 = -2+3 = 1

a rectangular prism has a base that is 6 M by 3.5 m in the prism is 9 meters high what is the surface area of the prism​
alexira [117]

Answer:

213 meters squared

Step-by-step explanation:

The surface area of a rectangular prism is found using the formula A=2(wl+hl+hw). Here substitute l = 6, w = 3.5 and h = 9.

A = 2((3.5*6) + (9*6) + (3.5*9))

A = 2(21 + 54 + 31.5)

A = 2(106.5)

A = 213
