You used 3/8 of a tank of gas on a trip to the mountains and you used 1/6 of a tank of gas doing errands. You want to visit your

friend who lives out of town. The trip requires 2/5 of a tank of gas. You say there is enough gas left for the trip. Is this reasonable?

Answer:

Yes

Step-by-step explanation:

This is reasonable because if you do :

                                                 3/8 - 1/6=

                                   3x3 over 8x3 - 1x4 over 6x4 =

   

                                          9/24 - 4/24 =  9-4 over 24 =

                                                       5/24 and that is greater then 2/5.

If a line crosses the y-axis at (0,1) and has a slope of 4/5, what is the equation of the line ?
stepladder [879]
The slope intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).  We are given that the slope is 4/5 and the point (0,1) so we know m=4/5 and b=1 so:

y=4x/5+1  now to rearrange into standard form ax+by=c

y=(4x+5)/5

5y=4x+5

5y-4x=5

So the answer is D.

However, by convention, in standard form, the equation is usually expressed with a positive coefficient for x.

5y-4x=5 SHOULD be expresses so the x has a positive coefficient, divide both sides by -1 and you have the technically correct form:

4x-5y=-5

Apparently whomever/whatever posed this question to you was unaware of this convention :P

In a triangle the first angle is 10 degrees more than the second angle. The third angle is equal to the sum of first 2 angles .
timurjin [86]
First angle= x+10
Second angle = x
Third angle = x+x+10 or 2x+10

X+10+x+2x +10=180
4x+20=180
Subtract 20 from both sides
4x=160
Divide both sides by 4
X=40
First angle =50
Second angle=40
Third angle =90
