Answer:
14.6°C
Step-by-step explanation:
Method 1
Higher value - lower value
12.2°C - (-2.4°C) *two negatives make a positive
12.2 + 2.4
14.6°C
Method 2
-2.4°C to 0°C = 2.4 increase (+2.4°C)
0°C to 12.2°C = 12.2 increase (+12.2°C)
Total change = 12.2 + 2.4= 14.6°C
B - 63 Degrees, obviously because all angles add up to a sum of 180 degrees.
Answer:
He needs $1.64 he has to pay $26.64
Step-by-step explanation:
$25 is what Edwin has
5.95 x 2 = $11.19
$2.50 x 3 = $7.50
11.19 + 7.50 + 7.95 = $26.64
So, there will be 40 green cars. if we want the ratio to be 1:3, we will need there to b three times as many silver cars as green cars: 40*3=120.
we already have 20 silver, so we need to add 120-20, that is 100 silver cars!
