Answer:
choice 2) x+2y+3 = 7
Step-by-step explanation:
equation to match:
x+2y = 4
add 3 to each side
x+2y+3 = 7 (which is the same as choice 2, x+2y+3 = 7)

Answer:
15, 16, 17
Step-by-step explanation:
let the consecutive numbers be n , n + 1 , n+ 2 , then
n + n + 2 = 32 ( sum of first and third )
2n + 2 = 32 ( subtract 2 from both sides )
2n = 30 ( divide both sides by 2 )
n = 15
n + 1 = 15 + 1 = 16
n + 2 = 15 + 2 = 17
The 3 numbers are 15, 16, 17
Answer:
B) 40 feet
Step-by-step explanation:
Essentially, there are two similar right triangles in the given problem.
base_<em>L </em> = Base [larger triangle] = 60 ft
base_<em>S </em> = Base [smaller triangle] = 6 ft
x = leg (larger triangle)
y = leg (smaller triangle) = 4 ft
Using the given proportion to solve for the value of x:
6x = 240
Divide both sides by 6:
6x/6 = 240/6
x = 40
