The answer to (-7)+1+4= -2
First, a little housekeeping!!
1+1+7x2+7y3+3+2x2−y3 needs to be written as <span>1+1+7x^2+7y^3+3+2x^2−y^3. The " ^ " signifies exponentiation and is essential here.
Now combine like terms:
7y^3-y^3 + 7x^2 + 2x^2 + 1 + 1 + 3
You'll get 6y^3 +9x^2 + 5.</span>
Answer:
x = 4
Step-by-step explanation:
6x - 8 = 4x
<em>subtract 4x from both sides of the equation</em>
6x - 4x -8 = 4x - 4x
2x - 8 = 0
<em>add 8 to both sides of the equation</em>
2x - 8 + 8 = 0 + 8
2x = 8
<em>divide both sides of the equation by 2</em>
2x/2 = 8/2
x = 4
One cubic foot of sand should be $11.25. You can find this answer by dividing the first price by 3, because there are 3 feet in a yard.
