Answer:correction so 1] y = 3x + 7
// Plug this in for variable y in equation [2]
[2] 5x + 2•(3x+7) = 3
[2] 11x = -11
// Solve equation [2] for the variable x
[2] 11x = - 11
[2] x = - 1
// By now we know this much :
x = -1
y = 3x+7
// Use the x value to solve for y
y = 3(-1)+7 = 4

Answer:
2/5
Step-by-step explanation:
1/5 / 1/2= 1/5 x 2/1
2/5
Answer:
16(x + 3)
4(7x + 8y)
w(11 + h)
Step-by-step explanation:
16x + 48
The greatest common factor of 16 and 48 = 16
Hence, expressing 16x + 48 in factored form:
16x + 48 = 16(x + 3)
28x + 32y
Greatest common factor of 28 and 32 = 4
Hence,
28x + 32y = 4(7x + 8y)
11w + hw
11w + hw = w(11 + h)
Answer:
B=43 C=137 D=48
Step-by-step explanation:
b=43 because any small triangle you subtract each angle from 180 . 180-89-48= 43
c=137 because angle b and c make a supplementary angle so you subtract b from 180 to get c. 180-43= 137
d=48 because <edc is congruent to <eyx so they are the same size
