Answer:
x=-61
Step-by-step explanation:
For parallelograms you always have the sum as 180,
You get 90+90+2x+3+119=180, then solve!
Answer:
27
Step-by-step explanation:
x - y = -3
multiply everything by -1
-x+y = 3
(y-x) = 3
(y-x)^3 = 3^3 = 27
Well , 10% is 5 g so if you times those 5 g by 3 it is 15 g there are 15 grams of cocoa in the chocolate bar
First combine like term
(-5x^3+2x^3) + x = 7- 3x^3
After add -5x^3 and +2x^3 together because it has like term is equal -3x^3
-3x^3 + x = 7-3x^3
Plus -3x^3 from both side
Left x alone you get
X= 7
