Answer:
just substitute y+2 instead of x in the 2nd equation
y+2+y=10
2y+2=10
2y=10-2
2y=8
y=4
to get x we use equation 1
since we have got the y value
x=4+2
x=6
So your answer will be A in the method (x,y)
Fraction= 4/5 . Your first fraction will be 8/10 then you divide the numerator and denominator by 2 . You final answer is 4/5
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56
truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour

Answer:
6 games
Step-by-step explanation:
Use the equation 2.5+3.25x=22 to solve in which $2.50 is the initial amount to rent for Bowling, $3.25 the amount of game that is played, $22 for what you have, and x in which is the amount of games you can play at the max. Subtract 2.5 on both sides to get to 3.25x = 19.5. Divide 3.25 on both sides to get your final answer as 6 for your x value in which you can play up to 6 games.
