Answer:
6 pounds of green candy
Step-by-step explanation:
Let r be the weight of red candy
Let g be the weight of green candy
Total weight = 10 pounds
r + g = 10 -------------------------(I)
Total cost = $ 38.50
2.50r + 4.75g = 38.50 --------------(II)
Multiply equation (I) by -2.50
(I)* (-2.50) -2.50r - 2.50g = -25.0
(II) <u>2.50r + 4.75g = 38.50 </u> {Now add and r will be eliminated}
2.25g = 13.50
g =13.50/2.25
g = 6
Plug in the value of g in equation (I)
r + 6 = 10
r = 10 - 6
r = 4
Answer: -6x^7
Step-by-step explanation:
2x^3 × (-3x^4)
=(2×-3) · (x^3 × x^4) ⇔ multiply the like terms
=-6 × [x^(3+4)] ⇔ the multiplication of exponents works as addition if same base
=-6x^7

28.32552
Step-by-step explanation:
39.331×0.72=28.32552
Hello!
Answer:
Starting with:
5x + 4(-x - 2) = -5x + 2(x - 1) + 12
Distribute terms outside of the parenthesis:
5x + 4(-x) + 4(-2) = -5x + 2(x) + 2(-1) + 12
5x - 4x - 8 = -5x + 2x - 2 + 12
Combine like terms:
x - 8 = -3x + 10
Isolate for the "x" variable by adding 3x for both sides:
4x - 8 = 10
Add 8 to both sides:
4x = 18
Divide both sides by 4:
x = 18/4
x = 4.5
Hope this helped! :)
