Answer:
10^7
Step-by-step explanation:
There are 7 zeros, so the number is the product of 10 multiplied by itself 7 times: 10^7.
__
Multiplying a number by 10 adds a zero on its right (moves the decimal point right one place).
1×10 = 10¹ = 10
1×10×10×10 = 10³ = 1000
1000×1000×10 = 10³×10³×10¹ = 10^(3+3+1) = 10^7 = 10,000,000
I think it’s A. If not, then B.
42.5%
17/40=0.425
0.425*100=42.5%
If
and
, then you can replace
in either equation with the equivalent expression given by the other equation. In this case, you have

and you can solve for
.

Then
.
For the second system, you can write


Then substitute this into the second equation and you get


so that
