Answer:
A) X + Y = 12
B) 10Y + x = 10x + Y -18
B) 9Y = 9x -18 multiplying A) by -9
A) -9Y = 9x - 72 adding A and B we get
0 = 18x -90
x = 5
The number is 75
Double-Check
7 + 5 = 12
75 -57 = 18
Step-by-step explanation:
I’m learning this too.. so what you do it see what will the number he if it was a while line so to find that out you will add 7+7 and get 14 so that’s the whole
So 7 x 7 will equal 49 and 49 x 3.14 will give you 153.86 as the answer
Answer:
the number is 126
Step-by-step explanation:
1) multiply each side by 32: (n-2) / 32 = 4
2) subtract 2 from each side: n-2 = 128
3) n = 126
Answer:

Step-by-step explanation:
I'm not sure if you had a typographical error with this statement, "5 to the fourth power, over 25 = 52."
According to the <u>Quotient Rule of Exponents</u><u>:</u>

Method 1:
In order for you apply the Quotient Rule, the base must be the same. Since 5 is a factor of 25, then you could rewrite 25 as 5². Doing so will give you the following exponential expression:

Method 2:
Even if you solve the given problem manually, you'd still get the same answer:

Both methods produced the same result, proving that the correct answer is 25.

Answer:
20.4 ft
Step-by-step explanation:
Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.
6/9.7 = ?/33
A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.
This gives you 20.4 ft
