Answer: x = 1

:
Per the author, the equation to solve is 12 = 5x + 7
Isolate the "x" variable by subtracting 7 from both sides of the equation:
12 = 5x + 7
-7 = -7
---------------------
12-7 = 5x + 0
or
5 = 5x
Dividing both sides by 5 gives x - 1

Answer:
(x - 5) (x - 7)
Step-by-step explanation:
<em><u>To factor this trinomial, you must split the middle term (-12x) into two terms that can be added to get -12x, and multiplied to get 35:</u></em>
<em><u /></em>
- 12x + 35
-7x - 5x + 35
<em><u>Group:</u></em>
(
-7x) (-5x + 35)
<em><u>Take out the GCF (Greatest Common Factor):</u></em>
x(x - 7) -5(x - 7)
(x - 5) (x - 7)
Answer: C, D
<u>Explanation:</u>
Length: L = x + 3
width: x ≥ y + 2 ⇒ y ≤ x - 2
wheels: y
0.50(L * x) + 4(2.25y) ≤ 50
0.50(x + 3)(x) + 4(2.25y) ≤ 50
0.50(x² + 3x) + 9y ≤ 50
9y ≤ 50 - 0.50(x² + 3x)
<u>9y</u> ≤ <u>50 - 0.50x² - 1.5x</u>
÷9 ÷9
y ≤

15 per person is the rate
22 is the constant
y = 15x + 22
