Answer:
b = -4
Step-by-step explanation:
-3(6b + 4) = 2(-5b + 10)
-18b - 12 = -10b + 20
(-18b + 10b) - 12 = (-10b + 10b) + 20
-8b - 12 = 20
-8b (- 12 + 12) = 20 + 12
-8b = 32
-8b/-8 = 32/-8
b = -4
solution is (- 1, 1 )
given the 2 equations
2x - y = - 3 → (1)
x + y = 0 → (2)
add (1) and (2) term by term to eliminate the term in y
3x = - 3 ( divide both sides by 3 )
x = - 1
substitute x = - 1 in either of the 2 equations and solve for y
(2) : - 1 + y = 0 ( add 1 to both sides )
y = 1
solution is (- 1, 1 )
E is the answer. In order for Trevor to make more than 180, the number of total hours he works has to be greater than (>) $180. French hours are $15 an hour represented by 15x and ice cream hours are $10 an hour represented by 10y. So 15x+10y>180.
