From the problem, we have :
Using distributive property, multiply 3 to the expression inside the parenthesis.
This will be :
The answer is 27x - 3
Answer:
Step-by-step explanation:
We can use exponent rules to try and simplify this expression down.
Exponent rules tell us that 
.
This means that since we have the same base on both terms (7 and 7), we can add the exponents to get a simplified expression.
So our simplified expression is 
.
Hope this helped!
There are 12 months in a year
4 months that have 30 days so ratio of the months with 30 days to the months with other than 30 days = 4: 12 = 1:3
Answer:
1 to 3
--------------
24 sedans and 18 sports
Ratio of sedans to sport = 24 : 18 = 4:3
Answer:
4 to 3
---------------
30 inches to 2 feet
2 feet = 24 inches
so 30 inches to 24 inches = 30:24
simplify
= 5 : 4
Answer:
5 to 4
-------------------
36 inches to 4 feet = 36 inches to 48 inches = 36:48
simplify
= 3 : 4
Answer:
3 to 4

We are going to define two equations where b means bagels and m will be muffins, First equation: 10*b + 4*m = 13 Second equation: 5*b + 8*m = 14 From the second equation, we can isolate b: b = (14 - 8*m)/5 In the second equation 10*(14 - 8*m)/5 + 4*m = 13 2*(14 - 8*m) + 4*m = 13 28 - 16*m + 4*m = 13 28 -13 = 16*m - 4*m 15 = 12*m m = 15/12 = 1.25 Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8 So one bagel costs $0.8 and one muffin $1.25
