Answer:
x - 6
Step-by-step explanation:
(4x2 + x - 5) - (5x2 - 1)
According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.
Then we do the multiplication because it comes before addition and subtraction.
4x2 = 8
Now we have 8 + x - 5
Combine like terms and 8-5=3 so we have 3 + x
Now for the second one.
5x2=10
10-1=9
Subtracting this from the first expression we have:
3+x-9 =
x - 6
Answer:
G
Step-by-step explanation:
Set-up a proportion with equal ratios.
Solve for x by cross multiplying.
3*106 = 50*x
318 = 50x
6.36 = x
The answer exactly is 93.5% because 58 over 62 is 0.935 then multiply it by 100 and there's your answer!
