Answer:
12
Step-by-step explanation:
You look at the graph seeing before the 20, that one has 4 and rhe other has 8. Add 8 and 4 to get 12.
The square root of 64 is greater than the square root of 25; (square root sign) 64 > (square root sign) 25
3a + b = 54...when b = 9
3a + 9 = 54
3a = 54 - 9
3a = 45
a = 45/3
a = 15 <===
Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.
I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...
-2/30 + -5/30 = -7/30
I think it’s 1/3 hope it helps
