Answer:
x = 17.5
Step-by-step explanation:
5/8 = x/28
=> 5(28) = 8x
=> 140 = 8x
=> 8x = 140
=> x = 140/8
=> x = 70/4
=> x = 35/2
=> x = 17.5

Answer:
$70 each
Step-by-step explanation:
If 4 friends each buy a hat, that would be $50 because that is $12.50X4=%50.00. Then, Since the total is $190 and $50 is off the chart, you would be left with $140 to spend on two t-shirts. Finally, since they are the same price, you divide $140/2=$70. Each t-shirt is $70.
Let me know if you need clarification and I will help the best I can. Have a nice day. :)
Answer:
table f is the one that is proportional
Step-by-step explanation:
on the graph start at the origin (0,0) then go to the right once and then go up twice and place a point. Then go over once again and go up 2 lines again and place another. Repeat this process five times.
The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.
