Answer: Choice B) x = 65, y = 10</h3>
====================================================
Work Shown:
The upper pair of angles 60 degrees and (2x-y) degrees are supplementary angles. This is because of the parallel lines. Note how they are same side interior angles. Therefore, (2x-y) and 60 combine to 180 degrees like so
(2x-y)+60 = 180
2x-y = 180-60 ... subtract 60 from both sides
2x-y = 120 ... call this equation 1
-------
Similarly, (2x+y) and 40 also combine to 180
(2x+y) + 40 = 180
2x+y = 180-40 ... subtract 40 from both sides
2x+y = 140 ... call this equation 2
------
Line up equation 1 and equation 2. Then add straight down
That becomes 4x = 260 which solves to x = 65 when you divide both sides by 4.
------
If x = 65, then,
2x-y = 120
2(65)-y = 120
130 - y = 120
-y = 120-130
-y = -10
y = 10
or
2x+y = 140
2(65)+y = 140
130+y = 140
y = 140-130
y = 10
----------
Either way end up with x = 65 and y = 10
Hello there.
<span>There were 196 students that participated in a clean-up event at a nearby lake. this is one fourth of the entire student population. write and solve an equation to find the number of students at this school.
Answer: x is the number of students in the school.
</span>
= 196.
<span>196 x 4 = 784.
Therefore the number of students in this school is
784.
Hope This Helps You!Good Luck Studying ^-^</span>
Answer: answer is C
Step-by-step explanation:
You got the area of the rectangle right the 12 by 8 it is 96
but you forgot about the triangle on top
Here are the formula's
rectangle: a=lw
triangle: a=hb/2
so the base of the triangle is 12 and the height is 4
12·4=48
48÷2=24
so you have to add 96+24=120
so c is your answer
