Answer:
The amount of reward that Sophia receives is ![\$13](https://tex.z-dn.net/?f=%5C%2413)
Step-by-step explanation:
Let
x------> amount of reward that Sophia receives
y-----> amount of reward that Isabella receives
we know that
![\frac{x}{y}=\frac{1}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%3D%5Cfrac%7B1%7D%7B8%7D)
------> equation A
-----> equation B
Substitute equation A in equation B
![\frac{1}{8}y+y=117](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B8%7Dy%2By%3D117)
![\frac{9}{8}y=117](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B8%7Dy%3D117)
![y=117*8/9=\$104](https://tex.z-dn.net/?f=y%3D117%2A8%2F9%3D%5C%24104)
Find the value of x
![x=\frac{1}{8}(104)=\$13](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B8%7D%28104%29%3D%5C%2413)
Answer:
15°C
Step-by-step explanation:
Find the difference by subtracting -4.8 from 10.2
10.2 - (-4.8)
Subtracting a negative number changes to adding a positive number:
10.2 + 4.8
= 15
So, the difference in temperature between the two cities is 15°C
Answer:
24
Step-by-step explanation:
Therefore our proportion is: (where x is the "vertical" rise)
Slope is defined as rise over fun so....
12/100 = x/200
(12*200)/100 = x
24 feet = x
