Answer:
30%
Step-by-step explanation:
1/5 = 20%
so, 50 - 20 = 30
Answer:
a= (y-4x-6)/X
Step-by-step explanation:
Make ax the subject of the formulae
-ax=4x+6-y
Multiply both sides by minus (-)
ax= y-4x-6
Divide both sides by x
a= (y-4x-6)/x
+2x-15=0
+2x=0+15
2x=15
X=15/2
X=15/2 or 7,5
Answer:
The answer would be the first one, combining 8 and -2
Step-by-step explanation:
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]
