He earns 1800 so, 3000 minus 1800 is 1200, if u set this up as a proportional relationship you'll get 1200 = 3
x 100
cross multiply the relationship, 1200 by 100 is 120,000, 3 by x is 3x, 3x=120,000 isolate the variable so you divide 3x by 3 and get 1x,
what you do to one side you have to do to the other
so 120,000 divide by 3 is 40,000. If max wants to earn at least 3000 this month he will have to sell at least 40,000 dollars in items
Answer:
x = 10.3 in
Step-by-step explanation:
To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.
A = 1/2x²
53 = 1/2x²
106 = x²
√106 = x
10.3 = x
The answer will be 720,000. Hopes This Helps
Answer:
1. $66
2. 30 + 4r
Step-by-step explanation:
Let
Price of admission into the park=$30
Price of every ride in the park=$4
Number of rides =x
Total cost of going to the park= 30+4x
1. How much money would Claire have to pay in total if she goes on 9 rides
Total cost of going to the park= 30+4x
When x=9
=30+4x
= 30 + 4(9)
=30 + 36
=$66
2. How much would she have to pay if she goes on r rides?
When x=r
Total cost of going to the park= 30+4x
= 30 + 4(r)
=30 + 4r
