Answer:
0.45
3.25
Step-by-step explanation:
16.25 ÷ 5 = 3.25
15.25 - 3.25 × 4 = 2.25
2.25 ÷ 5 = 0.45
Check Answer:
3.25 × 5 = 16.25
0.45 × 4 = 2.25
3.25 - 2.25 = 1
16.25 - 1 = 15.25

Answer:
x=-7
y=6
Step-by-step explanation:
7x+10y=11
4x+3y=-10
-3(7x+10y=11
10(4x+3y=-10
-21x-30y=-33
40x+30y=-100
19x = -133 (divide 19 on both sides)
x= -7
Now put the x in one of the original questions.
7(-7)+10y=11
-49+10y=11 (Add 49 to both sides)
10y=60 (Divide 10 on both sides)
y=6

Step-by-step explanation:
To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:
237.037 = 17.6
172.2 = X
X = 172.2 x 17.6 / 237.037
X = 3,030.72 / 237.037
X = 12.78
Thus, the expected price of the good in the year 2000 is $ 12.78.
