Answer:
64.94
Explanation
You arrange the numbers in such a way, to be in line with their decimal points like this:
70.7
-5.76
Then you subtract. Notice that on top of the 6 is nothing which is equal to 0
24 3-pound bags(72 pounds) and 10 5-pound bags(50 pounds). 72+50 = 122 pounds, 24+10 bags = 34 bags.
Answer:
equation of the table is y=30x+60
60 degrees is what the temperature starts at
to get to 440 degrees he needs 12 minutes and 40 seconds
Step-by-step explanation:
the change in y over change in x is 90/3 which is the slope
slope is 30
if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept
440=30x+60
380=30x
x=12 2/3
x= 12 minutes and 40 seconds
Answer:
90deg
Step-by-step explanation:
If the angles are supplementary, that means mA + mB = 180*
we know that
mA = (2x + 8)deg
mB = (2x + 8)deg = mA
mA + mB = 180deg
mB + mB = 2mB = 180deg
mB = 90deg
Note, that we did not need to compute x even, because the angles were the same.
