Answer:
Step-by-step explanation:
Yesterday, her rate was 8mph, her time was x hours.
Today, her rate was 13mph, her time was 13 - x hours.
So the total distance she biked on the two days is
d = 8x + 13(13 - x), or 169 - 5x
Use the special triangles ratio.
If it is a 45-45-90 triangle, the sides are

and 7
I think it is a 30-60-90 triangle though. This gets you 14 and
Answer:
slope = - 3 y-intercept = 36
Step-by-step explanation:
12x + 4y = 144 , will allow this to be done.
so 4y = - 12x + 144
now dividing both sides of the equation by 4 will give
y = - 3x + 36 , which is now in the required form
slope = - 3 and y-intercept = 36
Answer:
Step-by-step explanation:
3/4 of total = 45
therefore, 1/4 took bananas
the ones taking bananas are 3 times less than those who took apples.
so we get 45/3 = 15 people picking bananas
