Answer:
1/5x - 12 = -7
Step-by-step explanation:
The first thing says 12 less THAN. Normally, when you see something in word problems like "less than" it means you need to switch the places.
So rather than 12 - 1/5, it's 1/5 - 12.
1/5 of a number means you are multiplying that number by 1/5. we'll use x (or any letter really, doesn't matter) to represent the unknown number.
Remember that if a variable and number is written together, it means multiplication.
So, 1/5x - 12 = -7.
Answer:
−(9x^2+4x−1216)
Step-by-step explanation:
I believe this is the answer!
First off, mass is not measured in pounds, weight is.
But, I can still solve this for you!
1/14 * 3/4
3/56 pounds is your answer
Hope this helps!
is the original fraction
let the denominator of the original fraction be n, then
is the original fraction
adding 2 to the numerator gives
= , hence
= ( cross- multiply )
7(n - 2) = 5n
7n - 14 = 5n ( subtract 5n from both sides )
2n - 14 = 0 ( add 14 to both sides )
2n = 14 ( divide both sides by 2 )
n = 7
original fraction = =
