Make them improper fractions first....then.....
"Keep" ......"Change" ....... "Flip"
A + B = 142
A - B = 24 add these
2A = 166 → A = 83
And B = 142 - A = 142 - 83 = 59
Area to paint = [25 * 60] - 5[8 *10] = 1100 sq ft
Gals needed = 1100/ 275 = 4
$7200 X .04 = $288
(12+4)(5+1)-19 =
(16)(6) - 19 =
96 - 19 =
77
Example ???
500* 1.23 = 615 €
The common ratio = 1.5....so.....
S12 = [1 - (1.5)^12] / [ 1 - 1.5] = 257.49267578125
100%.....each integer 100-999 has at least one digit....!!!!!
8 pizzas / 10 students =
(8/10) pizzas per student =
