Answer:
3/2 OR 1 1/2
Step-by-step explanation:
Collect like terms, meaning combine both y's. You should have something like this afterwards.
6y = 9
Now that you have that divide the 6 on both sides so Y is by itself!

A is your answer the this question
Answer:
She did not qualify the exam.
Step-by-step explanation:
Given data
Total no of question in a test = 20
No. of question answered correctly = 16
Percentage of question answered correctly

But in order to get in the exam the student must have to score at least 90 %. But she got only 80 % so she did not qualify the exam.
(7.2 × 10^7) ÷ (9 × 10^4)
= (7.2 / 9) x 10^(7 - 4)
= 0.8 x 10^3
= 8 x 10^2
Answer
C. 8 × 10^2
50+79=129
180-129=51
X=51
Explanations
Angles on a straight line add up to 180 degrees. So 180-101=79 degrees
50 degrees is an opposite angle so it moves into the internal angle.
Angles in a triangle add up to 180 so (180-50-79=51)
Ans is 51 I think
