A! You need to multiply all the numbers together
Answer:
2.50(10) + 3x = 135.97, x = 38.66
Step-by-step explanation:
This should be pretty simple.
Basically, we know that he bought 10 pairs for 2.50 so that's $25 right there.
Our total is 135.97 though-
so here, we take our total from the right side of the equation, and subtract 25 from that.
135.97 - 25 = 115.97
Since he bought three pairs, divide it by 3.
115.97 / 3 = 38.66
One pair of shoes costs $38.66 - hope this helps!
A decimal that is like .11 the amount of #s in the decimal is 2 so it'll mean 2 0s like that would be 11/100. So if it was .209 it would be 209/1000.
Answer:
15%
Step-by-step explanation:
not that hard just make it a decimal then at the point go back twice and there its 15%
Answer:
Add the exponents and keep the bases the same. Then find the reciprocal and change the sign of the exponent
Step-by-step explanation:
When multiplying exponents with the same base number, you can add the powers. (If it was dividing, you would subtract the powers). You would then get 
.
- 2³ = 8,
- 2² = 4,
- 2^1 = 2,
- 2^0 = 1
The pattern is to divide by 2. This means that would be 1 ÷ 2 which is 1/2.
Tip: Any number to the power of -1 means to give its reciprocal.
Hope this helps!
