first you need to multiply it
0.4, 41%, 3/7
Explain: 0.4 is 40%, which is less than 41%. 3/7 is about 43%
Answer:
x = 2
Step-by-step explanation:
To find the x-value that makes the equation true, we would have to solve for x in the equation. To do that, we would have to get the equation in the form x = _. That would be our answer.
4x - 3 = -9 + 7x
Add 9 to both sides to get rid of the -9 on the right side.
4x - 3 + 9 = 7x
Simplify.
4x + 6 = 7x
Subtract 4x from both sides to get rid of the 4x on the left side.
6 = 7x - 4x
Simplify.
6 = 3x
3x = 6
Divide both sides by 3 to get rid of the coefficient of 3 on the left side.
x = 6/3
Simplify.
x = 2
So, the x-value that makes the equation true would be 2.
I hope this helps. :)
Answer:
<em>-21-15g</em> you cant solve you can simplify
ANSWER IS 5
so
how many years ago=x
so
'in how many years ago (-x) was ethan 5 times older than son
40-x means ethan's age x years ago
12-x means son's age x years ago
so
ethan's age x years ago is 5 times as much as son's age 5 years ago
40-x=5(12-x)
distribute using a(b+c)=ab+ac
40-x=60-5x
add 5x
40+4x=60
subtract 40
4x=20
divide 4
x=5
ANSWER IS 5 years
