What is 791=1/2h (26.5+30)
Answers
Following the order of PEMDAS, start with what's inside of the parenthesis, adding 26.5 with 30 ---> 791 = 1/2h(56.5) You need to get h on one side of the equation by itself. To do this, divide the whole equation by .5 (which is the same as 1/2), canceling out the 1/2 on one side of the equation. 791/.5 = 1/2h(56.5)/.5 ----> 1582 = h(56.5) Next, divide the entire equation again by 56.5. 1582/56.5 = h(56.5)/56.5 ---> 28 = h Your final answer is h = 28. To check this, plug 28 into the equation where the value h is.
Which relations are functions and which are not functions?Column A Column B 1. {(2, 2), (4, 4), (6, 6), (8, 8)} 2. {(0, 3), (3, 5), (5, 6), (8, 4)} 3. {(1, 2), (3, 3), (4, 8), (6, 3)} 4. {(3, 4), (5, 2), (5, 6), (7, 3)}
A. function B. not a function
Answers
A) A B) A C)A D) B Reason I know this is because if we look at the x number in all of these, if 2 are the same (like 2,6 and 2,4) then its a non function. But if none of the x =the same value its a function. Same goes for B C and now D, is a non function because out X's: 3 5 5 7 5 was repeated so it's a nonfunction. Got it?

How to solve 8=3/4w on math
Answers
When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.
8 = 3/4 w Divide by 3/4
w = 8/(3/4)
w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.
w = (8 x 4) / 3
w = 32 / 3
w = 10 2/3
You want to isolate the variable w so you want it by itself. To do so with a fraction multiply both sides by the fraction's denominator... 8(4)=3w 32=3w Now you want to divide both sides by 3 32/3=w 10.67=w This should be your answer :)
