Answer: he watched 1/12 of the movie at night.
Step-by-step explanation:
Let x represent how much of the movie that he watched at night.
Tanner watched 1/4 of a movie in the morning, and he watched some at night. This means that she had already watched
x + 1/4 = (4x + 1)/4 of the movie by the end of the day. Therefore, what he has left to watch would be
1 - (4x + 1)/4 = [4 - (4x + 1)]/4
= (3 - 4x)/4
By the end of the day, he still had 2/3 of the movie to watch, it means that
(3 - 4x)/4 = 2/3
Cross multiplying, it becomes
3(3 - 4x) = 4 × 2
9 - 12x = 8
12x = 1
x = 1/12
Answer:
4
Step-by-step explanation:
So your equation is 1.6(x-y)/2
Since x=10, and y=5, we need to substitute the amounts in to the equation.
so...
1.6(10 -5)/2
Using PEMDAS, parenthesis comes first. So solve what 's in the parenthesis (10 - 5).
So..
1.6(5)/2
Next, multiply 1.6 by 5.
1.6 x 5 = 8.
So you are left with the equation
8/2
and 8 divided by 2 is...
4!
Answer:
327
Step-by-step explanation:
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
