Subtract 4 from both sides. Square each side. Subtract 33 from both sides. Divide each side by 8. Your answer is -3.
12)
Square both sides. Put all numbers on one side of the equation so that you can be equal to zero. Factor out and solve for x.

45 7/8 out of 100 meters... how do I solve this?
Answers
(367/8) / 100) = .45875. Then you could move the decimal place over and you would get 45.875% which when rounded would be 46%. You can do this on a calculator to check by finding the decimal value of 7/8 which is .875, then add 45 to it to get 45.875. when you put this number over 100 you get 45.875/100 or .45875. multiply by 100 to get your percent 45.875%, round, 46%, and thats your answer
Answer:
45.875%
Step-by-step explanation:
45 7/8 out of 100 meters
= ((45*8+7)/8)*(1/100)
= ((360+7)/8)*(1/100)
= (367/8)*(1/100)
= 367/800
=0.45875
=0.45875*100 (convert to %)
=45.875%

What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the liketerms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We can use a proportion to solve the problem:
10 left-handed students out of 85 total students is equivalent to x left-handed students out of 391 total students:
10/85 = x/391
To solve for x, we can cross-multiply:
85x = 10 x 391
Then divide both sides by 85:
x = (10 x 391) / 85
Simplifying the right-hand side gives:
x = 46
Thus,
There are 46 left-handed students in Tom's school.

Then 85 × 4.6 = 391
So 10 × 4.6 =46
So there are 46 kids in Toms school that are eft handed out of every 391 students.

15*(37+8) / 3
Then,
15*(45) / 3
Next, you multiply the 15 by 45
15*(45) / 3
Next,
675 / 3
Last, divide 675 and you get:
