The answer is $3.74
Hope this helps
Multiply both sides by 3
Simplify the numerators
Multiply both sides by 6
Simplify the numerator
Multiply both sides by x
12x - 18 = 15x Subtract 12x from both sides
-18 = 3x Divide both sides by 3
-6 = x Switch the sides to make it easier to read
x = -6
Check your answer by plugging -6 in for the x in the original problem:
Plug in -6 for x
Change
to
so all denominators are the same
Change
to
for easier work
Subtract the numerators (4 - (-1) )
=
So,
x = -6 .
The answer is: x<12
Steps by steps
5(x+5)<85
Divide each term by 5 and simplify.
5(x+5)÷5<85÷5
Reduce the expression by cancelling the common factors.
x+5<85÷5
Divide 85 by 5.
x+5<17
Move all terms NOT containing "x" to the right side of the inequality.
Subtract 5 from both sides of the inequality.
x<-5+17
Add -5 and 17.
=x<12
Answer:
If Father is four times older than Mary, that would be 4 times 10-- which equals 40. Five years ago, Mary must have been 5 years old. So, multiply 7 and 5 and you'll get 35! Father would have been 35 years old.
