Answer:
B or C
Step-by-step explanation:It ain´t easy
Its an equilateral triangle so all sides are equal.
2x + 5 = 4x - 1
5 = 2x - 1
6 = 2x
3 = x
Do you get it?
Answer: When they work 10 hours each, they both make $300.
kelli y = 20x + 100
karl y = 25x + 50
substitution:
y = 20x + 100
25x + 50 = 20x + 100
-20x -50 -20x -50
--------------------------------
5x = <span>50
</span>5 5
x = 10
(Then plug into any equation)
y = 25x + 50
y = 25(10) + 50
y = 300
When they work 10 hours each, they both make $300.
<u>k / 9 = 12</u>
Multiply each side of the equation by 9 : <em>k = 108</em>
<u>84 n = 504</u>
Divide each side of the equation by 84 : <em>n = 6</em>
<u>6 = m / 148</u>
Multiply each side of the equation by 148 : <em>888 = m</em>
