Answer:
There is <u>8</u> adults and <u>1 </u>child
Step-by-step explanation:
<u>$78 - $6 = $72</u>
<u>$72 divided by 9 = 8</u>
you would add nine <u>8</u> times and add 6 to it then it would be $78
Hope this helps you! :)
Divide the two numbers. The equation is 420/15=28. So Lee would get 28 miles per gallon of gasoline. I hope this helps!
The equation of the straight line is y=mx+q where q is the number on the y-axis where the line passes, as you can see it is -3. It turns into:
y=mx+(-3) -> y=mx-3
Then consider a point on the line and take the coordinates, such as the point with coordinates (-2;-4), so now you know that:
x=-2 and y=-4
At this point you put these values into the equation:
y=mx-3
-4=m(-2)-3
then solve:
-4=-2m-3
-2m=+3-4
-2m=-1
m=+1/2
Put the value of m into the equation and you found it:
y=1/2x-3
83.33 should be the right answer.
Hope it helps.
-5y+8=-3y+10
-5y+3y=10-8
-2y=2
-2y/-2=2/-2
y=-1
I grouped the alike variable to one side, and the number to the other side, added and subtracted it, divided both sides by -2, and got -1
