Answer:
x = ¹⁰⁄₄,⁵⁄₂, or 2.5
Step-by-step explanation:
Given: 13 - 2(2x + 1) = 1
1. Distribute -2 through the parentheses:
⇒ 13 - 2(2x + 1) = 1
⇒ 13 + (-2)(2x) + (-2)(1) = 1
13 - 4x - 2 = 1
2. Combine like terms:
⇒ 13 - 4x - 2 = 1
⟹ 11 - 4x = 1
3. Subtract 11 from both sides:
⇒ 11 - 11 - 4x = 1 - 11
⟹ -4x = -10
4. Divide both sides by -4:
⇒ -4x ÷ -4 = -10 ÷ -4
⟹ x = ¹⁰⁄₄,⁵⁄₂, or 2.5
5. Check your work:
⇒ 13 - 2(2x + 1) = 1
⇒ 13 - 2(2(2.5) + 1) = 1
⇒ 13 - 2(5 + 1) = 1
⇒ 13 - 2(6) = 1
⇒ 13 - 12 = 1
⟹ 1 = 1 ✔

Answer:
14
Step-by-step explanation:
This can be solved by writing 2 equations and solving simultaneously.
Let <em><u>number of Adult tickets be A, and number of child tickets be C.</u></em>
<em><u /></em>
<u><em>"Bob bought 24 hockey tickets":</em></u>

<em><u>"Adult tickets cost $5.50, and child tickets cost $2.00...Bob bought 24 hockey tickets for $83":</u></em>

Now we can solve the first equation for A and substitute in 2nd equation and get the value of C.
A + C = 24
A = 24 - C
Now,
5.5 A + 2 C = 83
5.5 (24 - C) + 2C = 83
132 - 5.5C + 2C = 83
-3.5 C = 83 - 132
-3.5C = - 49
C = 14
Hence, Bob bought 14 child tickets
Answer:
D.
Step-by-step explanation:
First, you have to solve all of the options. The only option that makes since is D. To solve D, add 4 to both sides. That will leave you with y=3x+10. The slope of that equation is 3 and the y-intercept is 10. The line crosses the y-axis at 10, and goes up three and to the right one.
