Answer: $11.81✔️cost of the sandwich before tax

Step-by-step explanation:

Let C = cost before tax

Cell phone costs = C + C·5% = $12.40

C(1 + 0.05) = $12.40

C = $12.40/1.05 = $11.81 , cost before tax

Answer: $11.81✔️ cost of the sandwich before tax

<h3>Checking</h3>

Cell phone after tax = $11.81 + $11.81·5/100

Cell phone after tax = $11.81 + $0.59 = $12.40✔️checked!

Jackson is two times older than Shelly. If the sum of their ages is 18, how old is Jackson?
salantis [7]
Answer: jackson is 12

explanation:
let the age be represented by x
jackson is 2 times older than shelly so
2x is jackson’s age and x is shelly’s age

since the sum of their ages is 18 then:
2x + x = 18

solve:
3x = 18 ➔ divide by 3 on both sides
x = 6

so now we know shelly is 6

jackson is 2 times older than her so:
2(6) = 12

Step-by-step explanation:

To find the surface area of the triangular prism, you need to find the area of all the sides and add them together. The two triangular bases have already been established to have an area of 3 square units each, so together they have an area of 6 units. Two of the rectangular sides have dimensions of 3.5 by 2.5 units, while one has dimensions 3.5 by 3 units. Adding all of this together, you get a total of 34 square inches, or option e. Hope this helps!

First, put the numbers in order
A. 1,2,3,4,5,7,8,8,9.....median (middle number) is 5..when there is an odd number of data values, there will only be one median.
B. 14,14,15,16,17,18,19,20....if there is an even number of data points, there will be 2 middle numbers. In that case, u add the 2 middle numbers and divide by 2 to find the median. (16 + 17) / 2 = 33/2 = 16.5 is ur median.
