Answer:
5r + (5 x 6) = 84
looking for rice per pound.
Step-by-step explanation:
5r + (5 x 6) = 84
This shows an equation where we need to make r the subject to establish how many pounds a bag of rice weighs.
5r + (5 x 6) = 84
5r + (30) = 84
5r = 84-30
5r = 54/5
r = 10 4/5
r = 10.8 pounds

Umm. there are more pairs then tiles?
Step-by-step explanation:
Hm. This is an interesting problem.
Let's see if we can express each of these numbers in terms of x and make an algebra equation to help us solve.
Consecutive even numbers increase by 2.
Let's allow x to equal our first number.
Let's allow x + 2 to equal our 2nd number.
Let's allow x + 4 to equal our 3rd number.
When we add those together, their sum need to equal 50 more than the largest integer (our x + 4)
Let's set it up!
x + (x +2) + (x + 4) = (x + 4) + 50
Simplify!
3x + 6 = x + 54
Let's reorganize the left and right sides.
3x - x = 54 - 6
2x = 48
x = 24 (our 1st even number)
Now, let's check our answer!
24 + 26 + 28 = 78
78 - 50 = 28 Our highest integer.
The sum of consecutive integers 24, 26, 28 is 50 more than the highest integer.
Answer:
12 Tables.
Step-by-step explanation:
There are many ways you can solve this with, here is the simplest.
Lets make it as a statement, IF 1 table has 5 chairs THEN how many X tables have 60 chairs.
Make it simplier:
1 Table = 5 Chairs
X Tables = 60 Chairs
using the cross multiplication method you will get
5X = 60
Divide by 5
X = 12
Which means that the room has 12 tables.
