Lol i was working on this earlier. First get rid of the parenthesis by distributing the powers to the other powers.
27/4x(6)y(8)
the () are for powers
Answer:
Equation: ![\frac{3}{4}n+8=n-20](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dn%2B8%3Dn-20)
Solve for n: n = 112
Step-by-step explanation:
To first set up the equation, you need to look at the verbal description and translate into numbers and operations:
'three fourths a number' = ![\frac{3}{4} n](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20n)
'plus 8' = + 8
'is' =
'20 less' = - 20
'the number' = n
Put the expressions together:
'three fourths a number plus 8': ![\frac{3}{4}n+8](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dn%2B8)
'20 less than the number': n - 20
Set them equal to each other and solve: ![\frac{3}{4}n+8=n-20](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dn%2B8%3Dn-20)
Add 20 to both sides: ![\frac{3}{4}n+8+20=n-20+20](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dn%2B8%2B20%3Dn-20%2B20)
Subtract
from both sides: ![\frac{3}{4}n-\frac{3}{4}n+28=n-\frac{3}{4}n](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dn-%5Cfrac%7B3%7D%7B4%7Dn%2B28%3Dn-%5Cfrac%7B3%7D%7B4%7Dn)
Multiply both sides by
: ![\frac{4}{1}28=\frac{1}{4}n\frac{4}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B1%7D28%3D%5Cfrac%7B1%7D%7B4%7Dn%5Cfrac%7B4%7D%7B1%7D)
Solve for n: n = 112
Answer:
1 1/4 or 5/4
Step-by-step explanation:
Divide 5 by 4
Answer:
Each table is $6 and each chair is $2.50
Step-by-step explanation:
Answer:
D. 22 Cars and 8 Vans
Step-by-step explanation:
1. You multiply 22 x 150 = 3,300.
2. Then you multiply 300 x 8 = 2,400.
3. Next, add 3,300 + 2,400
4. That equals 5700.
Hopefully, that helps!
