Solve the following multiplication and division problems. a. 10 yd. × 3 yd. b. 15 ft. × 18 ft. c. 13 yd. 2 ft. 6 in. × 15 d. 198 sq. yd. 8 sq. ft. × 7

Step-by-step explanation:

a. 10 yd.×3 yd.=30 square yards;

b. 15 ft.×18 ft.=279 square feets;

c. 13 yd.=13×3 ft.=39 ft.=39×12 in.=468 in., 2 ft. 6 in.=2×12+6 in.=30 in., then 13 yd. 2 ft. 6 in.×15=498 in. × 15=7470 in.;

d. 198 sq. yd.=198 ×9 sq. ft.=1782 sq. ft.

198 sq. yd. 8 sq. ft. =1782+8 sq. ft.=1790 sq. ft.

Then 1790 sq. ft. × 7=12530 sq. ft.

To solve these problems, we just need to multiply or divide.

To solve problem c and d, we need to transform all units to the same, and then operate.

Remember that

To solve this one, we need to transform all lengths to yards. We know that 1 yard equals 3 feet and 1 feet equals 12 inches. So,

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
