First distribute the negative over the parentheses:-
= 7s^2 + 3s - 4s^2 + 3s - 1
= 3s^2 +6s - 1
Answer:
fraction: 10/35
decimal: .2857
percent: 28.57%
Step-by-step explanation:
for decimals you divide (10/35)
for percents you divide then multiply by 100 (10/35 = .2857 x 100 = 28.57%)
First you need to distribute the 1/2 by the numbers in the parentheses
1/2•4x and 1/2•10 which equals
2x+5=10
next, you will need to get the 2x by itself so you would do
2x+5=10
-5=-5
2x=5
finally, you divide the 2 by the 5 so you can get the x by itself
2x divided by 5
the answer is: x=2.5
