Simply substitute the given number for all the equations.
17) 5b + 1 = 16 where b is -3
5(-3) + 1 = 16
-15 + 1 = 16
-14 ≠ 16
So, the given number is not a solution.
19) 2 = 10 - 4y where y is 2
2 = 10 - 4(2)
2 = 10 - 8
2 = 2
The given number is a solution.
21) -6b + 5 = 1 where b is 0.5
-6(0.5) + 5 = 1
-3 + 5 = 1
2 ≠ 1
The given number is not a solution.

Answer:
the operation we use to convert quarts to liters : multiply
Step-by-step explanation:
One quart is approximately equal to 0.95 liter
Here quart is the larger unit and liter is the smaller unit
To convert larger unit to smaller unit we multiply
given that 1 quart = 0.95 liter
2 quart = 2 times 0.95
3 quart = 3 times 0.05
so to convert quart of liter we multiply
the operation we use to convert quarts to liters we multiply by 0.95
Answer:
i think it would be 8.7
Step-by-step explanation:
Answer:
1st, 3rd, 4th
Step-by-step explanation:
1st one: 43 x
multiply x by 43
7 x 43 = 301
7 x 43 = 258
10 x 43 = 430
3 x 43 = 129
4 x 43 = 172
(correct)
2nd one: 12x
multiply x by 12
2 x 12= 32
we know that 2 x 12 is 2 so this equation does not work
(incorrect)
3rd one: 202x
multiply x by 202
6 x 202 = 1212
4 x 202 = 808
10 x 202 = 2020
3 x 202 = 606
8 x 202 = 1616
(correct)
4th one: 13x
multiply x by 3
9 x 13 = 117
2 x 13 = 26
7 x 13 = 91
3 x 13 = 36
10 x 13 = 130
(correct)
