32 divided by (3+7) = 3.2
3.2x3= 9.6
3.2x7= 22.4
Therefore 9.6:22.4
<u>Answer:</u>
<u>Solution:</u>
-x - 6y = -23
<u>Now, let's substitute the value of y into the first equation.</u>
- x + 4y = 17
- => x + 4(3) = 17
- => x + 12 = 17
- => x = 5
<u>Let's check our answer to make sure it is correct.</u>
<u>Check:</u>
- -x - 6y = -23
- => -(5) - 6(3) = -23
- => -5 - 18 = -23
- => -23 = -23
Hence, this is proven correct.
Hoped this helped.
To solve this problem you first need to establish what it is you are looking for.. if you knew the grandson age then you could find your son and you. So that is what we need to find and since we don't know it, we will call it x.
Grandson = x
Son = 7x
You = 12x
Then it says the sum of the 3 is 100.... x + 7x + 12x = 100 then solve and find that x = 5. So to determine your age, just put 5 in for x and you get 60... dang your old ha
The answer is B., based on the distributive property (multiply coeffictients, add exponents, change signs because of the negative number being multiplied)
