Answer:
x = 30
Step-by-step explanation:
If the angles are supplementary, that means that they add up to 180°.
That means 40 + 4x + 20 = 180°
Simplify: 60 + 4x = 180
Subtract: 4x = 120
Divide: x = 30
Answer:
A. Tennis: 6x+12
A. Basketball: 7x+36
B. Tennis: Length- 36, Width- 72
B. Basketball: Length- 50, Width: 94
Step-by-step explanation:
A. Tennis
perimeter equation: P= 2L+2W
P=2(x)+2(2x+6) simplify
P= 2x+4x+12
P=6x+12
A. Basketball
P= 2(1/2x+32)+2(3x-14) simplify
P=7x+36
B. Tennis and basketball
just plug in 36 for x for the original lengeth and width equations for each court
Answer:
To find a 20 percent tip quickly, first find 10%, and then multiply it by 2.
Step-by-step explanation:
To find 10%, move the decimal 1 place to the left. So 10% of 53.82 is 5.382. Let's round that to 5.4 to simplify. Multiply it by 2 to get to 20% which is 10.8 and round to the nearest dollar to make $11.

Answer:
300 students
Step-by-step explanation:
To know the number of students, we must divide the total amount of milk spent by the amount spent for each and in this way we will obtain the value we are looking for, like this (both have the same units of L, so there is no problem ):
30 / (1/10) = 300
that is to say that there are a total of 300 students
