Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
C = 1.15
Answer:
35
Step-by-step explanation:
4.55÷0.13=35
if you check your work
0.13×35=4.55 as well
It is more appropriate to report this rate as 8 kilometers per second because centimeters is too small to measure how far a space shuttle can travel every second. Just as we don't use centimeters to measure how far a car can travel in an hour, we don't use centimeters to measure such things. Thus, using kilometers is more appropriate because the the number reported is smaller, making it easier for us to use.

Answer:
x=8
Step-by-step explanation:
CBA=DAB=42(Alternate angle)
x+CAB+DAB=180(Straight line)
x+130+42=180
x=180-42-130
x=8
