Complete question :
Taylor earns $5 each time she walks her neighbor's dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.
Answer:
12
Step-by-step explanation:
Amount earned for walking dog = $5 per walk
Amount already earned = $25
How many more times dog needs to be walked to buy a bike which costs $83
Target amount = 83
(Target amount - already earned amount) / amount earned per Walk
(83 - 25) / 5
58 / 5
= 11.6
Hence, Taylor needs to walk her neighbor's dog 12 more times
Answer: 40
Explanation: The least common multiple (LCM) of 2 numbers is the smallest number that they both divide evenly into.
The smallest number that both 8 and 20 divide evenly into is 40.
2x+29=10x-27
29=8x-27
56=8x
x=7
2(7)+29=43
10(7)-27=43
360-43(2)=274
274/2=137
measure of V = 137
