Answer:
120 +10w = 75 + 15w, w=weeks, found by adding savings to rate times and unknown variable of weeks and setting equal to each other. 9 wks, $210
Step-by-step explanation:
120 +10w = 75 + 15w
120-75= - 10w+15w
45=5w
45/5=9
9 weeks
120 + 90 = 75 + 135
210= 210
Answer:
The answer to your question is 128°F
Step-by-step explanation:
Data
Temperature on Mars = -67°F
The Temperature on Earth = 61°F
Process
1.- Subtract the temperature of Mars to the temperature of the Earth.
ΔT = 61 - (-67)
2.- Simplification
ΔT = 61 + 67
3.- Result
ΔT = 128°F
4.- Conclusion
The Earth is 128°F warmer than Mars.
13/15 = 87%
This is because 13 divided by 15 is 87, so 13 is 87% of 15:)
