Dividing means you subtract the exponents. Dividing by a number is the same as changing the sign on the exponent.
x⁰/x² = x⁻² = 1/x²
y⁻³/y⁻¹ = y⁻³⁻⁻¹ = y⁻² = 1/y²
together is 1/x²y², answer B
Answer:
Josie and Emmanuel are the same.
Step-by-step explanation:
By pluggin the numbers given into the equations, you find that Josie and Emmanuel are 5/8 while Maria is 120.
Step 1: 0.416 = 416⁄1000
Step 2: Simplify 416⁄1000 = 52⁄125
Answers + Step-by-step explanation :
a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign
b) we can solve our equation to find for n, the number jim thought of
7(n + 5) = 91
I will use the distributive property.
7n + 35 = 91
Subtract 35 on both sides
7n = 56
Now divide 7 on both sides to find n
n = 8
The number Jim was thinking of was 8! this should be correct, hope this helps!
