Answer: Choice ARaising something to the 1/4th power is the same as applying the 4th root to that expression. Raising an expression to the 1/n power is the same as applying the nth root.
Rule:
![x^{1/n} = \sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B1%2Fn%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%7D%20)
(if the text is too small it basically says x to the (1/n) = square root with a small 'n' all over x)
$252/$28=9 lawns. $252 is the total money they earned, so divide it by the amount of money they charge per lawn.
Answer:
97, 485, 197
Step-by-step explanation:
<u>Given</u>:
- First number = a
- Second number = b
- Third number = c
<u>Then we have:</u>
- b = 5a
- c = 100+a
- a + b + c = 779
<u>Substituting b and c in the third equation:</u>
- a + 5a + 100+a = 779
- 100 + 7a = 779
- 7a = 779- 100
- 7a=679
- a= 679/7
- a = 97
- b= 5*97 = 485
- c = 100+ 97 = 197
