86+87/2 = 86.5
Answer:
The answer would be negative 8 because -8 + 5 = -3 and -3 x -2 = 6
Step-by-step explanation:
The answer would be negative 8 because -8 + 5 = -3 and -3 x -2 = 6
Answer:
x=10
Step-by-step explanation:
5x+20=4x+30
Subtract 4x from each side
5x-4x +20 = 4x-4x+30
x+20 = 30
Subtract 20 from each side
x+20-20 =30-20
x =10
Answer:
11
Step-by-step explanation:
1/5 x^2y - 1 2/3 y^2 x + 4 4/5 yx^2 - 1/3 xy^2
I will write the x and y terms in order for x and y
1/5 x^2y - 1 2/3 xy^2 + 4 4/5 x^2y - 1/3 xy^2
This way I can put the like terms together
1/5 x^2y + 4 4/5 x^2y- 1 2/3 xy^2 - 1/3 xy^2
Combine like terms
(1/5 + 4 4/5) x^2y - (1 2/3 + 1/3) xy^2
5 x^2 y - 2 xy^2
We know x =-2 and y = 1/2
5 ( -2)^2 (1/2) -2(-2) (1/2)^2
Calculating the powers first
5(4) (1/2) - 2(-2) (1/4)
10 - (-1)
10+1
