Answer: rate is a ratio that is used to compare different kinds of quantities. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
Answer:
x=-0.08 and y=2.92
Step-by-step explanation:
123x + 2(x+3) = -4 y = -0.08 + 3
123x + 2x + 6 = -4 = 2.92
125x + 6 = -4
125x = -10
x= -0.08
10b + 4m = 13....multiply by -2
5b + 8m = 14
------------------
-20b - 8m = - 26 (result of multiplying by -2)
5b + 8m = 14
-----------------add
-15b = - 12
b = -12/-15
b = 0.80 <=== bagels cost 0.80 each....80 cents each
10b + 4m = 13
10(0.80) + 4m = 13
8 + 4m = 13
4m = 13 - 8
4m = 5
m = 5/4
m = 1.25 <== muffins cost 1.25 each
