4(Q+R)
Step-by-step explanation:
Answer:
let me explain how you do this:
Step-by-step explanation:
first, you write your equation down:
-x + 5y = 8
next, group everything out seperately so you can know what to do in this problem, like grouping out each variable and number you see. then, figure out if the solution is simplified down to the last number. if so, if there is two variables that aren't the same, try and figure out a way to solve this equation with these two different variables. figure out if you have to multiply, subtract, add, or divide.
Answer:
Water left in tank is
gallons.
Step-by-step explanation:
Given :
Capacity of tank = 9.5 gallons ![=\frac{95}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B95%7D%7B10%7D)
Water taken out of tank =
gallons
We have to find the water left in the tank.
Water left in the tank = Total capacity of tank - water taken out of tank
=![\frac{95}{10}-\frac{19}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B95%7D%7B10%7D-%5Cfrac%7B19%7D%7B3%7D)
Taking LCM of (3,10)= 30
![\Rightarrow \frac{95 \times 3-19 \times10}{30}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B95%20%5Ctimes%203-19%20%5Ctimes10%7D%7B30%7D)
Solving further, we get,
![\Rightarrow \frac{285-190}{30}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B285-190%7D%7B30%7D)
![\Rightarrow \frac{95}{30}=\frac{19}{6}=3\frac{1}{6}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cfrac%7B95%7D%7B30%7D%3D%5Cfrac%7B19%7D%7B6%7D%3D3%5Cfrac%7B1%7D%7B6%7D)
Thus, Water left in tank is
gallons..
Answer: 5 valid arrangements
Step-by-step explanation:
This depends on whether the boys or girls swapping places are considered unique solutions. I'm going to assume that is no, because there would be an unrealistic amount of solutions if it is true.
Assuming G = girl and B = boy, these are the possible arrangements.
(I will bold the valid solutions).
GGBBBB
GBGBBB
GBBGBB
GBBBGB
GBBBBG
BGGBBB
BGBGBB
BGBBGB
BGBBBG
BBGGBB
BBGBBG
BBBGGB
BBBBGG
Thus, there are 5 valid arrangements.
