Answer:
$55
Step-by-step explanation:
5 tickets = $25
1 ticket = $5 (divide by 5 on both sides)
multiply by 11
11 tickets = 5 ×11
11 tickets = $55
7-4x= 31
Bring over 7 to the other side
Positive 7 changes into negative 7
7-7-4x= 31-7
-4x= 24
Divide by -4 for -4x and 24
-4x/-4= 24/-4
x= -6
Check answer by using substitution method
7-4x= 31
7-4(-6)= 31
7+24= 31
31= 31
Answer : C. x= -6
Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.

With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.

Answer : It'll take 3.43 hours to do the job if they work at the same rate.

Answer:
Angle A is 37 degrees, Angle B is 82 degrees, Angle C is 61 degrees
Step-by-step explanation:
Exterior angles are the supplement of interior angles, so subtract 143 from 180 to find Angle A.
180 - 143 = 37
All angles add up to 180.
37 + 61 = 98
180 - 98 = 82
Angle B is 82 degrees.
Hope this helped. :)
