Answer:
165 years old
Step-by-step explanation:
For now let his age be = x
According to the question,
4x - 500 = 160
4x = 160 + 500
4x = 660
x = 660 / 4
x = <u>165 years old</u>

Answer:
2^3 * 3
Step-by-step explanation:
Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23
<em>To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.</em>
This is much easier to do than it sounds like in this explanation.
Start with 24.
24/2 = 12
12/2 = 6
6/2 = 3 3 is not divisible by 2, so we move on to 3.
3/3 = 1 We got to 1, so we are done.
The prime factorization is the product of all the prime numbers we divided by which are in bold.
24 = 2 * 2 * 2 * 3
Now we index it:
24 = 2^3 * 3
Answer:
Option D: (8, -12) is the solution set for given system.
Step-by-step explanation:
Given that:
1/4x-1/2y=8 ----------- eq1
1/2x+3/4y=-5 --------- eq2
Multiplying eq1 by 2 we get:
1/2x - y = 16 ------- eq3
Now by subtracting eq3 from eq2 we get:
(1/2x+3/4y) - (1/2x - y ) = -5 -16
By simplifying:
3/4y + y = -21
By taking LCM to make denominator same:
3/4y + y*4/4 = -21
3+4 / 4y = -21
7/4y = -21
Multiplying both sides by 4/7 we get
y = -21 * 4/7
y = -12
Putting value of y in eq3
1/2x - (-12)= 16
1/2x + 12 = 16
1/2x = 16 - 12
1/2x = 4
Multiplying both sides by 2
x = 4*2
x = 8
So the solution set = (8, -12)
i hope it will help you!
