Total distance: d = 3 km
Minutes run: x
Distance run = (1 km / 2 minutes) * x = (1/2)x
Distance from the finish line = total distance - ditance run = 3 - (1/2)x =
= - (1/2)x + 3
Answer - (1/2)x + 3
6a+8b; when a variable is next to a coefficient then that means they are multiplying each other, we just don't know what a or b is.
Answer:
180
Step-by-step explanation:
If 35% did not wear happy faces, then 100% -35% = 65% did wear happy faces.
Then we have ...
... 117 = 65% × (all children)
... 117/0.65 = all children = 180 . . . . . . divide by 65% = 65/100 = 0.65
There were 180 children in all.

Answer:
x=8 and y=21
Step-by-step explanation:
12x-28=7x+12 (the 2 angles are equivalent)
12x-7x=12+28
5x=40
x=8
9y-77 + 12x-28 =180 (the sum of those 2 angles is a flat angle (180°))
9y-77+12*8-28=180
9y=180+28+77-96
9y=189
y=21
