Answer:
distribute -5 and -4
Step-by-step explanation:
-5(-6x-9y)-4(-10x+7y)
(30x + 45y) - (- 40x + 28)
30x + 45y + 40x - 28
45y + 70x - 28
Answer:
x = 36
Step-by-step explanation:
16 / (4/9) = 36
That's all there is to it. Hope I helped
Answer: 24
Step-by-step explanation:
Variation: y ∞ x
y = kx , where k is the constant of proportionality
now to find k, we substitute for y and x in the equation above
16 = 8k
therefore,
k = ¹⁶/₈
= 2.
Now, to find y , we move back to the equation above and substitute for x and k to get y
y = 12(2)
= 24
It is 5 because of the Pythagorean Theorem. 4^2 + 3^2 = c^2
16 + 9 = 25
v25 = 5
