Answer:
- y=0.8x
- See Explanation for others
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.
Answer:
Step-by-step explanation:
She paid $50 to activate one time and pays $20/ month
20.00x3=60.00
60.00+50.00=110.00
The diameter is 12 cm and the radius is alsays half of the diameter so it will be 6 cm
So first off, we need to establish that there are three terms that we need to find: a, c & E.
Let's write the three equations below:
Equation No. 1 -
a + c - 2E = 2
Equation No. 2 -
a - 2c = 5
Equation No. 3 -
- c + E = 4
To begin working out our answer, we will make (a) the subject of our second equation & (E) the subject of the third equation so that we can substitute them into the first equation as displayed below:
Equation No. 2 -
a - 2c = 5
a = 5 + 2c
Equation No. 3 -
- c + E = 4
E - c = 4
E = 4 + c
From there, we substitute the given equations for (a) & (E) into the first equation in order to make (c) the subject in the first equation as displayed below:
Equation No. 1 -
a + c - 2E = 2
( 5 + 2c ) + c - 2 ( 4 + c ) = 2
5 + 3c - 8 - 2c = 2
3c - 2c = 2 - 5 + 8
c = 5
Extending from this, by substituting the value of c, which is 5, into Equation No. 2 & 3, we will be able to also obtain the values of both (a) & (E) as displayed below:
Equation No. 2 -
a = 5 + 2c
a = 5 + 2 ( 5 )
a = 5 + 10
a = 15
Equation No. 3 -
E = 4 + c
E = 4 + ( 5 )
E = 9
Therefore, we have now successfully found the values of a, c & E as displayed below:
a = 15
c = 5
E = 9
If you want to check your answer, then simply substitue the values into Equation No. 1. If after solving the equations, the left-hand & right-hand side are equivalent, then the answer is correct. However, if it isn't equivalent, then the answer is either incorrect or you have made an error while solving thr equation. Here is the working out to check your answer for this question:
a + c - 2E = 2
( 15 ) + ( 5 ) - 2 ( 9 ) = 2
20 - 18 = 2
2 = 2
Therefore, the solution is correct.
Answer:
C. 10cm
Step-by-step explanation:
First we can rearrange the equation to solve for length (l):
V = lwh
Divide both sides by wh:
l = V/(wh)
Substitute in known values:
l = 1200/(15x8)
l = 1200/120
l = 10cm
Hope this helped!
