Answer:
4
Step-by-step explanation:
60 minutes = 1 hour → 120 minutes = 2 hours. The purple bar represents at least 121 minutes, which is greater than 2 hours.
The answer is 7. You can look at it like this. The two triangles are similar and the larger one's sides are twice the size of the smaller one's. So then we know GF is twice the size of JK.
2(2y+5)=5y+3
4y+10=5y+3
y=7
First of all you have to make them equal to each other. What I mean is the following
3x+20=2x+40
Then you should just solve for x
It’s A, if you add 70 and 65 you get 135 and 180-135=45 :)
