<span>10x-5y=25 solve for y
so
10x - 5y = 25
5y = 10x - 25
y = 2x - 5
hope it helps</span>
Answer:
6x+5y
Step-by-step explanation:
Combining like terms (x and y)
we get
30x-24x=6x
6y-y=5y
=> 6x+5y
Answer:
1. 2³ × 2² = (2 × 2 × 2) × (2 × 2) = 23+2 = 2⁵
2. 3⁴ × 3² = (3 × 3 × 3 × 3) × (3 × 3) = 34+2 = 3⁶
3. (-3)³ × (-3)⁴ = [(-3) × (-3) × (-3)] × [(-3) × (-3) × (-3) × (-3)]
= (-3)3+4
= (-3)⁷
4. m⁵ × m³ = (m × m × m × m × m) × (m × m × m)
= m5+3
= m⁸
Step-by-step explanation:
exponential law
Step-by-step explanation:
If the library surveyed 240 people and only 15% chose documentaries, then only 36 people chose documentaries and the other 204 chose something else other than documentaries. You had to get 15% into decimal form and to do that you move the "." in 15.0% left 2 places so you get 0.15. Then you multiply 240 by 0.15 and you get 36.
If you are doing a multi step question that looks something like this: 23+(4)-4 or longer. You will have to use a formula called BEDMAS. It stands for brackets, exponents( which are little numbers on top of a number), then you deal with division, multiplication, addition, and subtraction. You will have to solve your equation in this order. If you don’t you will get another, answer.
