Answer:
B. 2x – 1 = 13 and x = 7
Step-by-step explanation:
We are given 4 equations and a solution for each. We have to tell which of the given solution satisfies the given equation.
Option A.
2x -1 = 13 and x = 6
Using this value in the equation, we get:
2(6) -1 = 13
12 - 1 = 13
11 = 13, which is not true. Hence this option is not valid
Option B.
2x - 1 = 13 and x = 7
Using the value in the equation, we get:
2(7) - 1 =13
14 - 1 =13
13 = 13, which is true. Hence this option is valid.
Option C.
2x + 1 =13 and x = 7
Using the value in the equation, we get:
2(7) + 1 = 13
15 = 13, which is not true. So this option is not valid
Option D.
2x - 1 = 13 and x = 11
Using this value in the equation, we get:
2(11) - 1 = 13
21 = 13, which is not true. Hence this option is not valid.
How many times were they swung? 0.0 .....
if swung twice.. I think the answer would be 27.16
.
2d+3
2(8)+3
Multiply 2 and 8
16+3
19
So the answer is 19
Answer:
$27.25
Step-by-step explanation:
Answer:
If you simplify 2/6, you get 1/3 by dividing the numerator and denominator by 2.
Therefore, 1/3 and 2/6 would be the same point on the number line.
