3x - 6x + 14 = 2x + 39
-3x + 14 = 2x + 39
-5x = 25
x = -5
Answer:
x = 17º
Step-by-step explanation:
We know that it's a right angle because of the smaller square where the vertices meet. We are given 73º. An equation you can use is
90 - 73 = x
x = 17
If you would like to know how many people attended the reunion last year, you can calculate this using the following steps:
125% of last year's attendance is 160 people
125% of x is 160
125% * x = 160
125/100 * x = 160 /*100/125
x = 160 * 100 / 125
x = 128 people (last year)
Result: 128 people attended the reunion last year.
-4(2.5y-3.25) - 15.25 = -10y + box
-4(-0.75y) - 15.25 = -10y + box
3y-15.25 = -10y + box
-7y-15.25 = box
box and/or y = -22.25
i'm not 100 percent sure of my answer, but I'm pretty confident. If i am wrong, then all you need to do is distribute in the beginning.
4 1/4, 4 5/12, 4 2/3. Not sure if there is suppose to be a 4 in front of the 5/12 but if there is this is how it should be ordered
