When you say either, you add both A and B
0.3+0.4=0.7
Your answer is 0.70 which means 70%
Two consecutive integers would be x and x+ 1
if you multiply them you have x(x + 1) = x^2 + x
if you want the product to equal 90 you get x^2 + x = 90
The first option is correct.
Answer:
7.5 or 15/2 (Whatever form you need to use)
Step-by-step explanation:
N-5 divided by 2 =5
Combine like terms:
-5 divided by 2= -2.5.
N-2.5=5
Add -2.5 from itself, then do the same to the other side:
N-2.5=5
+2.5=+2.5 (Adding 2.5 to -2.5 cancels it out)
N=7.5
Combine like terms. The 5x is grouped to the 8x and the -7 isgrouped with the -55.
This means 5x + 8x = 13x and -7 - 55 = -62
The new expression is 13x - 62. We can't find the exact value of x because the expression wasn't set equal to anything.
