Answer:
# of laps < 28, the number of laps will be less than 28.

28 laps = 112 minutes
Because we want less than 28 laps,
27 laps = 108 minutes
She can run any amount of laps less than 28.

Answer: 0%
Step-by-step explanation:
There are 5 colors of jelly beans.
Kaz ate all the green beans, so now only 80% of the jelly beans remain.
Kaz ate half of the orange pieces so now only 70% of the jelly beans remain.
Then Kaz ate half of the remaining pieces, so only 35% of the beans remain.
Current numbers: 0% green, 5% orange, 10% red, yellow, blue
Then he eats red and yellow candies in equal proportions until only 15% of the beans remain. This means that he ate 20% worth of red and yellow beans. This means that he ate all of the red and yellow beans.
Thus, there are 0% red beans left.
Answer:
A
Step-by-step explanation:
x + y = 4a + 7
x - y = 2a + 5
In both equations, make x the subject of the formula
x = 4a + 7 - y equation 1
x = 2a + 5 + y equation 2
Subtract equation 2 from equation 1
2a + 2 -2y
= 2a + 2
