Answer:
x=31.25%
Step-by-step explanation:
set up a proportion as 15/48=x/100 and solve.
Answer:
-5
Step-by-step explanation:
Substituting x=4 into the equation gives a 2-step linear equation in y. It is solved by isolating the variable and making its coefficient be 1.

<h3>use x=4</h3>
When x=4, the equation becomes ...
-3x +9y = -57
-3(4) +9y = -57
-12 +9y = -57
<h3>solve 2-step equation</h3>
The <u>first step</u> is to "isolate" the variable term (9y) by adding the opposite of the constant that is on the same side of the equation. The result is that the variable term is by itself on one side of the equal sign.
-12 +12 +9y = -57 +12 . . . . . add the opposite of -12
9y = -45 . . . . . . . . . . . . . . simplify
The <u>second step</u> is to make the coefficient of y be 1. We do that by multiplying by its inverse, 1/9. Equivalently, we divide by 9.
(1/9)(9y) = (1/9)(-45) . . . . multiply by the inverse of 9
y = -5 . . . . . . simplify
Answer:
65mph
Step-by-step explanation:
forget about how far apart the cities are for now instead divide 260/4 because tia has traveled 260M for 4 hours
distance
-------------
time
260/4=65
Answer: 24165, I think
Step-by-step explanation:
I just multiply the kids that were there by the words they were each given
The answer would be y= 33/a+4 I hope is helps.
