WRITE THE EQUATIONS:
1) Twice a umber added to four 4 is 28
MY ANSWER: 4 + 2n = 28
2) a number subtracted from 9 is three times that number
MY ANSWER: 90 - n = 3n
3) The sum of two numbers is 180. One number is five times the other.
(NEED HELP W/ THIS ONE)
N=5M
N+M=180
5M+M=180
M=30, N=150
Thank you! Are my other answers correct?
on the second, I don't know if you should have 9, or 90
it should be 90. sorry bout that
To solve the third equation, let's break it down step by step:
1) Let's represent the first number as "x."
2) According to the problem, the other number is five times the first number. So, the second number can be represented as 5x.
3) The sum of the two numbers is 180. Therefore, the equation can be written as x + 5x = 180.
4) Combining like terms, we get 6x = 180.
5) To isolate x, we divide both sides of the equation by 6: x = 180 / 6.
Simplifying further, we get:
x = 30.
So, the first number is 30. To find the second number, we can substitute this value back into the equation:
Second number = 5x = 5 * 30 = 150.
Therefore, the two numbers are 30 and 150.
