Answer: 200x.2=40
Step-by-step explanation:
200 students under 25
20%=.2
times each other make up 40 percent of the students don't know how to drive
Answer:
-2
Assumption:
Find the value of x such that
.
Step-by-step explanation:



Combine like terms:

This is not too bad too factor on the left hand side since 2(2)=4 and 2+2=4.


So we need to solve:

Subtract 2 on both sides:

Let's check:






0 was the desired output of
.
Answer:
9.6 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opposite/ adjacent
tan 58 = BC / 6
Multiply each side by 6
6 tan 58 = BC
9.602007174 =BC
Round to the nearest tenth
9.6 = BC
5x + 2y - 2x + 8 = (5x - 2x) + 2y + 8 = 3x + 2y + 8
Step-by-step explanation:

Let's subtitute
for the above equation:
