Answer:
They purchased 6 dozen eggs
Step-by-step explanation:
The total cost is the cost per dozen times the number of dozen purchased
total cost = 1.98 * n where n is the number of dozen
11.88 = 1.98n
Divide each side by 1.98
11.88/1.98 = 1.98/1.98 * n
6=n
They purchased 6 dozen eggs
Commutative property of multiplication
If its perimeter, it should be quite easy to find. Just add 12+9+15. Which equals 36. So the perimeter is 36 inches. -Hope it helps!
Answer:
a. 47.6mph (distance divided by time = speed. divide each rowers distance by their speed, then add them all)
b. 1.26 minutes per mile (i used a calculator so i dunno how to explain)
let me know if this is right or not :)
Step-by-step explanation:
the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.
but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say
180 = ACB + ABC + CAB
180 = y + 180 - x + CAB
0 = y - x + CAB
x = y + CAB
x - y = CAB
therefore, the second answer option is correct.
