Answer:
the range is 5-8 hours
Step-by-step explanation:
325+175t=1200
175t=875
875/175
t=5
325+175t=1725
175t=1400
1400/175
t=8
Answer:
y = 6
x = 2
Step-by-step explanation:
rearrange the first equation in terms of x
x = (y - 2)/2
substiute x in the second equation
y = -5[(y-2)/2] +16
Now simpilify and solve for y
y = (-5y + 10)/2 +16
y = -5/2y + 5 + 16
y + 5/2y = 5 + 16
3.5y = 21
y = 6
Now substitue y in the first equation to solve for x
x = (6 - 2)/2
x = 2
Answer:
(7,-2)
Step-by-step explanation:
First, you move to the right of y-axis like 5 to 7,
then you movie to the up of x-axis like -5 to -2.
So the answer was (7,-2)
Answer:
y = 7
Step-by-step explanation:
An equilateral triangle has all its sides to be equal..
so.
10 = x
10 = y + 3
y = 10 - 3
y = 7
