The answer i came up with is 0.68 i don't know if thats what you need or not. hopefully i helped.
x = 112
This is because
<span>4/7x = 64 </span>
<span>7/4 x 4/7 = 64/1 x 7/4 </span>
<span>1x= 448/4 </span>
<span>
x = 112 </span>
I think the answer is D. hours because its variation does not depend on another variable
This translates to "a number" is greater than 45. All you have to do now is translate these words into an algebraic statement. Basically, you replace "a number" with the variable which it is defined for, and you use the "greater than" symbol to show that the variable is greater than the value of 45.
You just need to foil. 2x times 4x times 2x times 36 times 24 times 4x times 24times 36. then solve.
