<span> 1/2(8y-10z)-(3y+z)
= 4y - 5z - 3y - z
= y - 6z
hope it helps</span>
They are similar by number. But they are not perpendicular. 3x+4y=12 gives you a negative slope. But 4x-3y gives you a positive slope. So they would be crossing each other if put together. This means that Sadia is correct and Henri isn’t. Show all work: 4x-3y=12
4x-3y+3y=12+3y
4x=3y+12
4x/4=3y+12/4
X=3/4y+3
3x+4y=12
3x+4y+-4y=12+-4y
3x=-4y+12
3x/3=-4y+12/3
X=-4/3y+4
The measure of angle B is equal to 60 degrees.
In order to find this, we can first note that the angle C (in the right side triangle) is equal to 80 degrees. We can tell this because it creates a straight line with the other angle C and therefore the two combined give us 180 degrees.
Then we can add angle A, B and C together in the right side triangle to get 180 degrees since they are all the measures of angles in a triangle.
A + B + C = 180
2x + 3x + 80 = 180
5x + 80 = 180
5x = 100
x = 20
Now that we have the x value, we can plug into the equation for B.
B = 3x
B = 3(20)
B = 60
Answer:1/2=2/4=4/8
Step-by-step explanation:It's quite simple if you do 1/2 times 2 you would get 2/4 1*2=2 2*2=4 2/4 same with 2/4 time 2 2*2=4 4*2=8 4/8.
The answer is C: No the percentage of students that prefer sports is higher than the percentage of those that prefer movies! Hope this helps.
