10 - 7f = -8f
what is the awnser?

f = -10 because you add 8f on both sides causing it to be 10+f=0

Then, you subtract 10 from both sides to get f = -10

f = -10

Step-by-step explanation:

Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other.  Do the opposite of PEMDAS.

Note that: PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, to isolate the variable, add 7f to both sides of the equation:

10 - 7f (+7f) = -8f (+7f)

10 = -8f + 7f

Combine like terms:

10 = (-8f + 7f)

10 = -f

Isolate the variable, f. Divide -1 from both sides:

(10)/-1 = (-f)/-1

f = 10/-1

f = -10

f = -10 is your answer.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
