It's 34.
You can either intuitively know 25% means one-fourth and divide 136 by 4
Or
Convert the percentage to a decimal and multiply. 136 * 0.25 = 34
2x-2+x+5=90
3x+3=90
-3 -3
3x/3 =87/3
x=29
The best and most correct answers among the choices provided by the question are:
<span>▢A. -2x+3y=-15
▢B. y=2/3x-5</span>
y = mx + b. where m is the slope<span> of the line and b is the y-</span>intercept<span> of the line, or the y-coordinate of the point at which the line crosses the y-axis. To write an equation in </span>slope-intercept form<span>, given a graph of that equation, pick two points on the line and use them to find the </span>slope<span>.</span>

Answer:
The correct option is C. 9 houses could 18 men paint in 6 hours.
Step by step explanation:
Let the number of houses paint by 18 men in 6 hours be x.
One man can paint one house in 12 hours.
The part of house painted by a man in 1 hour is 
.
The part of house painted by a man in 6 hour is
The total number of men is 18. Therefore the number of houses painted by 18 men is
Therefore correct option is C. 9 houses could 18 men paint in 6 hours.
Answer:
Leslie has 13 quarters and 23 half-dollars.
Step-by-step explanation:
You can write the following equations from the information given and considering that a quarter is $0.25 and half-dollar is $0.50:
x+y=36 (1)
0.25x+0.50y=14.75 (2), where:
x=amount of quarters
y=amount of half-dollars
First, you can isolate x in (1):
x=36-y (3)
Then, you can replace (3) in (2):
0.25(36-y)+0.50y=14.75
9-0.25y+0.50y=14.75
0.25y=5.75
y=5.75/0.25
y=23
Finally, you can replace the value of y in (3) to find the value of x:
x=36-23
x=13
According to this, the answer is that Leslie has 13 quarters and 23 half-dollars.
