3/5 + 1/2
= 6/10 + 5/10
= 11/10
= 1.1 so the answer is 1.1
Simplify the whole numbers in the equation. isolate x by adding or subtracting on both sides of the equal sign. divide both sides by the number that's being multiplied to x (example 2x) then you have your answer so it'll be x=?
Answer:
Adult’s ticket = $ 18
Child’s ticket = $ 16
Step-by-step explanation:
Adults: x
Children: y
(3x + 4y = 118) * (2) = 6x + 8y = 236
(2x + 3y = 84) * (-3) = -6x - 9y = -252
Add both equations:
-y = - 16
y = 16
3x + 4(16) = 118
3X + 64 = 118
3X = 118 - 64
X = 54/3=18
You are adding 6 to each number. (N-1)+6, I guess
-20%
Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:
1) Find the difference between 30 and 24 as a number.
2) Divide the result from Step 1 by the starting number 30.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:
((24-30)/30)*100 = -20.00%
Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:
-20.00%
