9x4 can help you find 9x8 because after you find your answer all you have to do is add 9 four more times to get the sum of 9x8.

If you know that 9*4 is 36, then you multiply by two to get 9*8 which is 72, because 36 2=72

Anastasy [175]

Answer:

I'll setup the problem and you can compute the answer

Step-by-step explanation:

The formula for simple:

I = P*r*t

I = interest

P = loan amount

r = interest rate per period (period = days)

n = number of periods

P = 10,170

r = .0764/365

t = 272

Solve the following equation for N<br><br> 1/5 (N+3)+4=3/10 (2N-2)<br><br><br> n = ________
postnew [5]

Answer:

n = 13

Step-by-step explanation:

1/5(n + 3) + 4 = 3/10(2n - 2)

~Simplify both sides

1/5n + 3/5 + 4 = 3/5n - 3/5

~Combine like terms

1/5n + 23/5 = 3/5n - 3/5

~Subtract 23/5 to both sides

1/5n = 3/5n - 26/5

~Multiply 5 to both sides

n = 3n - 26

~Subtract 3n to both sides

-2n = -26

~Divide -2 to both sides

n = 13

Best of Luck!

PLS HELP ASAP NEED FOR A TEST
horrorfan [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x----> the first number

y----> the second number

we know that

\frac{x}{y}=\frac{3}{4}

so

y=\frac{4}{3}x -----> equation A

x+y=35 ----> equation B

substitute equation A in equation B

x+\frac{4}{3}x=35

\frac{3x+4x}{3}=35

\frac{7}{3}x=35    

x=35*3/7=15

y=35-15=20
