Answer:
C
Step-by-step explanation:
We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71 we can check our work by doing
42 + 67+ 71 = 180. We also know 67 + 42 = 109.
Lets look at our answers;
A. 109 = 180 + x When solved it gave me; x = -71. We got a positive 71 so this is incorrect.
B. x + 42 = 67 When solved it gave me; x = 25, which is incorrect.
C. x = 180 - 109 When solved it gave me; x = 71
D. 42 + 67 - x = 180 When solved it gave me; x = - 71
Therefore the answer is C.
Answer: y=54(lb)x+170(lb)
Step-by-step explanation: that's the function for it but I tried. You need to include how much weight the elevator can hold though
40/5 because to find the answer you would divided them
Answer:
2.57
Step-by-step explanation:
You first have to multiply the -5.3 times the -1.9. Once you do that, you get 10.07. Then, you add the -7.5.
Here are the equation steps:
(-7.5) + (-5.3)x(-1.9)
(-7.5) + (10.07)
2.57
