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.
Answer:
<h2>D) $1.05 ÷ 3</h2>
Step-by-step explanation:
Quarter = 0.25
Nickel = 0.05
3 Quarters = 0.25 * 3 = 0.75
6 Nickels = 0.05 * 6 = 0.30
Add to find the total amount of money they have:
0.75 + 0.30 = 1.05
They have to split it equally:
1.05 / 3
2+tan ×[-pi/4
2×10=20×16=[pi/320
