2x - 17?
= -17 +2x (using commutative property of addition, changing order and sum remains the same)
answer is A) -17 + 2x
♥ Let's solve:
15n+5n can be known as 15+5.
15+5=20 now add n.
Final answer: 20n
The equation would be 43.2 divided by 132 which would give you .32 aka 32%
Answer:
-6x+12
-9+5a
7x+63
8y-4/5x-12
Step-by-step explanation:
To solve these all you have to do is take the number outside of the parenthesis and multiply them by each term.
-3(2x)-3(-4) All I did here was expand the problem to show what i mean by terms.
-6x+12
Do this for each problem.
0.1(-90)+0.1(50a)
-9+5a
-7(-x)-7(-9) For this one you are taking negatives times negatives so each answer will be positive.
7x+63
4/5(10y)+4/5(-x)+4/5(-15)
8y-4/5x-12
Answer:
$1,075
Step-by-step explanation:
Use the formula I=PRT where I= interest, P=principle or starting amount, R=interest rate, T=time
1000*0.025*3=75
Add 75 to 1,000, 1,000+75=1,075
