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:
4 miles
Step-by-step explanation
If your mom can walk 1 mile in 14 minutes then 2 miles would take her 28 minutes 3 miles would take her 42 minutes and finally if she walked 4 miles it would take her 56 minutes.
14 + 14 + 14 + 14 = 56
14 x 4 = 56
Answer:
100 yds^2
Step-by-step explanation:
To find the area of a square, we need to know the length of one side of the square. Since the perimeter is 4 times the length of one side, or 4s, and since 4s = 40 yds, s must be 10 yds.
Then the area of the square is (10 yds)^2 = 100 yds^2.
Well, the standard equation is in the form:
ax + bx = c (constant).
Thus, x and b must be isolated together on one side with the constant on the other. The equation which satisfies this is:
A. -2x + y = 5
