If 5% of an amount equals 800,000, then what is that amount? Please I confused, can someone help me!

kondor19780726 [428]

Answer:

the amount is 16,000,000

Step-by-step explanation:

first let that amount be Y for an example. so...

$\frac{5}{100}*Y=800,000$

$\frac{5Y}{100}=800,000$

$5Y=800,000*100$

$5Y=80,000,000 (then you both divide by 5 in both sides so that Y is left alone.)$

$So Y=16,000,000$

so the amount you are looking for is 16,000,000

1/2x+y=-6 y=3/5x+5

substitute
1/2x+3/5x+5=-6

I have 4 factors. Three of my factors are 1, 2, and 6. What is my fourth factor?

SIZIF [17.4K]

The 4th factor would be 3. You would find this out through a factor tree. If you don't know the original number when you start you look at your numbers. A factor of 1 usually goes with the highest number, assuming that the number 6 is the highest factor, that would be the original number. As 2 is the other known factor than we know that 3 has to be the last factor, because 2 x 3 = 6. It cannot be the number 12 because then there would be 6 factors not the needed 4.
