Answer:
Step-by-step explanation:
← Equation 1
By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting 
from 
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,
Equation 2 multiplied by 3 will give,
Add those together,
(After simplifying 
values)
Therefor
By substituting to Equation 1 we get,
Therefor we can say,
Percent means parts out of 100
23%=23/100=0.23
'of' means mutiply
23% of 75=0.23 times 75=17.25
answer is 17.25
Answer: A)
x = # of students in math class
2x+7=40
B)
2x+7=40
-7
------------
2x = 33
--- ---
2 2
x = 76 students
The absolute value makes the -8 into a positive 8, then you subtract the 8 on both sides, giving you your answer 7. (Since 15-8=7)
The answers are A and B. hope this helps, have an amazing day :)
