Michael is 4 times as old as Brandon and is also 27 years older than Brandon. How old is Michael?
boyakko [2]

Answer:

Michael is 36 years old

Step-by-step explanation:

Let M represent Michael's age, and let B represent Brandon's age,

"Michael is 4 times as old as Brandon" becomes

   M = 4B

"Michael is also 27 years older than Brandon" becomes

    M = B + 27

Since the two equations are equal to M, they are equal to each other, so we have...

4B = B  + 27            now solve for B...

3B = 27

B = 9

There fore

M = 9 + 27 = 36

3^2•3^n simplifies to 3^20 what is the value of the exponent n?
Lemur [1.5K]
Given that:
3^2 \times 3^n = 3^20
Solving for n.
Divide both sides by 3²
\frac{3^2 \times 3^n}{3^2} = \frac{3^{20}}{3^2}
Simplify
3^n= 3^{20-2} \\
3^n=3^{18} \\
if \ a^{f(x)}=a^{g(x)} , \ then \ f(x)=g(x)
So, n=18

Answer: n=18

PLEASE<br> What is the solution to the equation 4 ( b − 2 ) − 10 = 2b + 6 ?
maxonik [38]
Answer: 12

Step by step explanation:
First simplify both sides of the equation
( 4 )( b ) + ( 4 ) ( - 2 ) + -10 = 2b + 6 (distribute)
4b + -8 + -10 = 2b + 6
(4b) + (-8 + -10 ) = 2b + 6 (combine like terms)
4b + -18 = 2b + 6
4b - 18 = 2b + 6
Then subtract 2b from both sides
4b - 18 - 2b = 2b + 6 - 2b
2b - 18 = 6
After that you add 18 to both sides
2b - 18 + 18 = 6 + 18
2b = 24
2b/2 = 24/2
b = 12
