Answer: 6 3/4
Step-by-step explanation:
1. Use proportion:
8:4.5=24:x
8x=24*4.5
x=3*4.5
x=13.5
2. Use proportion
8:4.5=4:x
x8=18
x=18/8
x=9/4
x=2.25
3. For 24 people you need 13,5
for 12 people you need :
24:13.5=12:x
x=13.5/2
x=6.75
Answer:
9
Step-by-step explanation:
10
Answer: 18
Step-by-step explanation:
First we need to solve for x to find the measure of the adjacent angle.
-6x+64 = 8x + 162
subtract 162 to leave x by itself
-6x- 98 = 8x
add 6x to both sides
-98 = 14x
now divide by 14
x = -7
Now solve one of the given equations to find the measure of the adjacent angle.
8(-7)+162
-56 + 162 = 106
Meaning the measure of angle 8 is 18
because they'll add up to 180(The measure of the line)

Answer:
5 months
Step-by-step explanation:
Value m= months
Gym A Money needed to pay= 30m+ 39
Gym B Money needed to pay= 20m+ 89
30m+ 39= 20m+ 89
Now isolate m
(30m-20m) + (39-39)= (20m-20m) + (89-39)
10m = 50
10m/10= 50/10
m=5; You can plug this number in to check my answer.
