Answer:
X>5
Step-by-step explanation:
Since the initial deposit is given as $2500 then to get more than $4000, Mr. Brown needs additional 4000-2500=$1500
Since each month he deposits $300 then after x months he will have more than $1500 additional.
4000<300x+2500
Collecting like terms
4000-2500<300x
1500<300x
Simplifying
5<x
Or
x>5

Answer:
72
Step-by-step explanation:
The triangles are said to be similar. (ΔNPQ ~ ΔRSQ) That means corresponding sides have the same ratio:
NP/RS = NQ/RQ = PQ/SQ = 24/32 = 21/28 = 3/4
This ratio, or scale factor, also applies to the perimeters of the two triangles.
perimeter NPQ / perimeter RSQ = 3/4
Using the given expressions for the perimeters, we have ...
(7x +2)/(10x -4) = 3/4
We can solve this equation in the usual way to find the value of x. Then we can use that value to find the perimeter of ΔNPQ.
4(7x +2) = 3(10x -4) . . . . . multiply both sides by 4(10x -4)
28x +8 = 30x -12 . . . . . eliminate parentheses
20 = 2x . . . . . . . . . . . add 12-28x to both sides
10 = x . . . . . . . . . . . divide both sides by 10
The perimeter of ΔNPQ is ...
7x +2 = 7(10) +2 = 72
The perimeter of triangle NPQ is 72 units.
Answer:
1433.09
Step-by-step explanation:
4,000,000 divided by 64 = 62,500
62,500 divided by 42 1,433.09
He makes 1433.09 per minute
