4x + 3y= 12
4x + 3*0= 12, x-int= 3
4*0 + 3y= 12, y-int= 4
Answer:
15.5 seconds.
Step-by-step explanation:
From the time the driver activated the brakes until he stopped, he travelled 76 - 14 = 62 meters.
During this time the car slowed down from 8 m/s to 0 m/s.
Assuming the deceleration was constant during this time we can apply one of the equations of motion for constant acceleration:
s = (u + v)t / 2 where u = initial velocity, v = final velocity, s = distance and t = the time, so:-
62 = (8 + 0)t/ 2
62 = 8t/2
4t = 62
t = 15.5 seconds.
Answer:
x=2 y=8 ---> (2;8)
Step-by-step explanation:
2x+5y=44
6x-4=y
1.
2x+5(6x-4)=44
2x+30x-20=44
32x=64
x=2
2.
6x-4=y
6*2-4=y
12-4=y
y=8
Answer:
There are 0.475 pounds of apples in each tart.
I arrived in this number by dividing the total number of pounds by the total number of tarts made.
475 pounds divided by 1000 tarts is equal to 0.475 pounds per tart.
475 lbs/1000 tarts = 0.475 lbs/tart
So, if you are to bake a certain number of tarts and need to know the total number of pounds of apple needed to bake you can use this equation.
y = 0.475x
where y represents the total number of pounds needed to bake x number of tarts with a fixed 0.475 pounds per tart.
