Answer:
95 students out of 125 students would be expected to have stleast one sibling
The equation system is
1.25x+0.75 (92-x)=87.5
Solve for x
1.25x+69-0.75x=87.5
0.5x+69=87.5
0.5x=87.5-69
0.5x=18.5
X=18.5÷0.5
X=37 units of candy bras
(92-37)=55 units of water bottles
Mr's Powell's class sold more items

So from above
Mr's Rodman's class earned more
Hope it helps!
Answer:
Step-by-step explanation:
Both angles together equal 180. Set up your formula as
-4x+5+-13x+39 = 180
Now move your terms to have all x values on one side
-4x-13x = 180-5-39
-17x = 136
x=136 / -17
Use this answer in place of your x in each equation to get the angle.
You got this!
