Equation is 2(3x+24)=9x+18
Answer is x=10

Bisector means it cuts it in half so ABD is the same as DBC. The whole angle is 9x+18 which is the same as doubling 3x+24 since thats half of if hence the equation 2(3x+24)=9x+18

To solve for x you have to distribute 2(3x+24) by multiplying 2 to 3x and 24
New equation is 6x+48=9x+18
Subtract 6x both sides
48=3x+18
Subtract 18 both sides
30=3x
Divide both sides by 3
10=x

a car travel 1/6 of a mile of the distance between two cites in 3/5 of an hour at this rate what is the fraction it will take to
Nikolay [14]

3/5 is 2/5 less than one whole

We need to find how much they traveled in 2/5 of an hour and add that to 1/6

In 1/5 of an hour,  they traveled 1/18 of a mile

(1/18)*2=1/9

1/9+1/6=10/36

10/36=5/18

They traveled 5/18 in one hour

If y varies directly as x, and y = 25 when x = 5, find y when x = 25.

When asked to write a point slope equation for a line passing through the points (-4,-7) and (3,2) a student wrote y-2=-9/7(x-3)
AleksAgata [21]
First let's find the slope
Slope formula: 
\frac{y_2-y_1}{x_2-x_1} =slope
Given the two coordinates: 
(-4,-7) (3,2) 
 x1,y1  x2,y2

Plug these numbers into the formula
\frac{2-(-7)}{3-(-4)} = \frac{9}{7}
In this case the mistake that was made was that the student wrote the slope negative instead of positive
Final answer: 
<span>y-2=9/7(x-3)</span>
