Answer: x = 1
Step-by-step explanation:
2.8 + 2x = 0.6 x 8
2.8 x + 2x = 4.8
2x = 4.8 - 2.8 (subtract 2.8 on both sides)
2x = 2
x = 1 (divide 2 on both sides)
Hope this helps
Answer:
7 inches
Step-by-step explanation:
The volume of a cylinder is calculated using
where r =4 inches is the radius and V=351.68 is the volume.
To find the height of the jar, we substitute these values and solve for h.
Divide both sides by 50.24 to get:
h=7 inches
Therefore the height of the jar is 7 inches
Answer:
159.25
Step-by-step explanation:
175 multiplied by 6% is 10.5
If you subtract 10.5 from 175 you will get 164.5
To answer the question above, we let s be the cost of a shirt and h be the cost of each hat such that the equations that would best represent the given are:
10s + 20h = 490
20s + 30h = 860
The system of equations is the answer to the first question and the values of s and h are $25 and $12, respectively.
The formula for volume is V=lhw, or length times height times weight. To find the length, you divide the volume by the height and width.
In this case, divide 3,060 first by 12, the height, then by 15, the width.
3,060/12=255
255/15=17
The length is 17.
