Answer:
After 5 weeks.
Step-by-step explanation:
Westley starts with $85 and saves $5 per week. So:

Buttercup starts with $10 and saves $20 per week. So:

When they have the same amount of money, the two equations will be equal to each other. Therefore:

Solve for x. Subtract 10 from both sides:

Subtract 5x from both sides:

Divide both sides by 15:

Westley and Buttercup will have the same amount of money after 5 weeks.
Answer:
275 miles in 5 hours
55 miles in one hour
Check
to check if im right
275×2 would be how many miles she drove in 10 hours rght ? 275×2=550
550 miles in 10 hours
we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550
10 hours plus 3 hours = 13 hours right ?
55 ×3 = 165
550 +165=715
715 miles in 13 hours
Step-by-step explanation:
715÷13 to get how many miles she drove in one hour .
=55 miles in 1 hour .
then multiply 55 ×5 to get how many miles she drove in 5 hours
55×5=275
275 miles in 5 hours
3 meters is the same thing as 12/4 meters so divide 12/4 by 3/4 to get 4.
Answer:
If
then
and 
Step-by-step explanation:
Solve two inequalities for x.
1. 
Separate terms with x and without x into two sides:

Multiply by -1:

2. 
Separate terms with x and without x into two sides:

Multiply by -1:

Find the largest set of x values satisfying both inequalities:

If
then
and
In this case both m and n are negative.
If
then
and 
If
then
and 
1) 2/3x , 2t , -1/3x
.
2) 2/3(3m^4 + 6) - (m^4 - m)
{ 3 and 3 get cancelled }
= 2m^4 + 6 - m^4 + m
= m^4 + 6 + m
.
Hope it helps! :)
