For this case we have the following situation:
The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.
So we have to define variables:
x: number of months
y: total cost
The mathematical expression that models the problem is:
Answer:
(3 7/8, -1 3/4)
Step-by-step explanation:
The midpoint is the average of the end point coordinates:
((5 1/2, -4 3/4) +(2 1/4, 1 1/4))/2
= (7 3/4, -3 1/2)/2 = (3 7/8, -1 3/4)
Divide the larger one by the smaller one. 2.4 divided by 0.3 gives you 8. That means the scale factor is 8, or the larger triangle is 8 times larger than the smaller. We can prove this by multiplying 0.3 by 8 and getting 2.4
Answer: Equation:
or
x is the cost of each shrub x = $10
Step-by-step explanation: Total bill = $62.50.
Subtract the cost of potting soil for $12.50 to find the cost of just the shrubs. 5x equals that amount
5x = 62.50 - 12.50
5x = 50 divide both sides by 5
5x/5 = 50/5
x = 10
Answer:
2 1/2
Step-by-step explanation:
Hope this helps :P
