Answer:
4(90) + 4(2)
Step-by-step explanation:
The given expression is 4(92)
This can be expressed as
This can also be expressed as
Using the distributive law of multiplication and additon,
a*(b+c) = a*b + a*c
In this case a=4
b=90 and c = 2
So the equivalent expression is
But this is the same as option 2 in the list of given options.
Hence the equivalent expression is 4(90) + 4(2)

Step-by-step explanation:
The 3 cans of beans had a total weight of 2.4 Pounds
Therefore:
- 1 can of beans = (2.4 ÷ 3) =0.8 Pounds
The following applies from the options.
- y=0.8x where y is the weight and x is the number of cans.
- A 2-column table with 3 rows. Column 1 is labeled number of cans with entries 5, 15, 20. Column 2 is labeled total weight (in pounds) with entries 4, 12, 16.
Using y=0.8x
When x=5, y=0.8 X 5=4
When x=15, y=0.8 X 15=12
When x=20, y=0.8 X 20=16
- On a coordinate plane, the x-axis is labeled number of cans and the y-axis is labeled total weight (in pounds. A line goes through points (5, 4) and (15, 12). This can be clearly seen from the table above as (5,4) and (15,12) are points on the line.
