Answer:
67.5
Step-by-step explanation:
If all triangles equal 180 degrees, and one angle is 45 degrees, you get the equation 180 = 45 + x + x which is the same as 180 = 45 + 2x, and instead of that equation, you can use 180 - 45 = 2x. That gives you 135 = 2x, and now divide both sides by 2 and you get 67.5 = x
Answer:
no solution
Step-by-step explanation:
X less than or equal to (< with the line underneath) -3 or x>0
1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
Answer:
28:26
Explanation:
Because a ratio compares things. Since there are 26 students on the floor, and 28 students on the bleachers, you would type 28:26.
