Answer:
292 and 2092
Step-by-step explanation:
Surface area:
Wall 1: 40 x 3 = 120m^2
Wall2: 40 x 3 = 120m^2
Wall 3: 15 x 3 = 45m^2
Wall 4: 15 x 3 = 45m^2
Ceiling: 15 x 40 = 600m^2
Total : 240 + 600 + 90 = 730
So, cost of painting = 730/25 x 10 = 29.2 x 10 = 292
Total: 292 + 1800 = 2092
Answer:
More Than
Step-by-step explanation:
According to the given statement:
This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.
The two words in this problem which tell us about the operation are "More Than"
This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.
Since, x represents the earnings of last year, we can represent the earnings of this year as:
Twice of x + 20
2x + 20
The question says:
4(x) +3 = 2(x) + 9
so now you need to find x
first you should add -2(x) on both sides of the equation and then add -3 on both sides:
4(x) - 2(x) = 9 - 3
2(x) = 6
now you can divide both sides by 2:
x = 6/2
x = 3 :)))

14.4%
L*W*H=V=10*9*4.5=405 in^3.
that is 50.5 in^3 over the estimate, or 14.4%
