Step-by-step explanation:
1) P = 47,100 + 2,550t
Given P = 95000
So,
95000 = 47100 + 2550t
Subtract 47100 from both sides,
95000 - 47100 = 2550t
47900 = 2550t
Divide by 2550,
t = 47900/2550 = 18.78 = 18.8 years
2) Given P = 43,100 + 3,150t
Both P must be equal.
47100+2550t = 43100+3150t
Subtract 43100 and 2550t from sides,
47100- 43100 = 3150t - 2550t
4000 = 600t
Divide by 600,
t = 4000/600 = 6.67 = 6.7 years
The number on the right is always greater than the number on the leftEx:14 is greater than 8 because 14 is to the right of 8 on the number line.
X + x+1 = 79
2x + 1 - 1 = 79 - 1
2x = 78
2x/2 = 78/2
x=39
Nick's number was 39
Here the dimension of the waxed gymnasium floor is given which is 20 feet by 20 feet. It means the floor is of square shape . And we need to find how many square feet she have to wax. Here square feet is given, which means we have to find the area. SO we need to find the area of the gymansium floor . And area of square is side square. So area of gymnasium floor = 20 ft times 20 ft = 400 square feet .
Answer:
4f + 3g
Step-by-step explanation:
g + 3f + f + g + g
3f + f = 4f
g + g = 2g + g = 3g
