Answer:
x= 26/5
Step-by-step explanation:
13 + x/2 = 3x Subtract 13 from both sides
x/2=3x-13 Mulitply both sides by 2
x= 6x - 26 Subtract 6x from both sides
-5x= -26 Divide both sides by -5
3×-7= -21
3×-x=-3x
-21-3x. =9

2
Change the subtraction to add 2x plus -4x
5=-4x (+2x)-7
5=-2x-7
since the x's are now on one side and we can't do anything with 5, on the other side you change -7 to add to the other side.
5 (+7)= -2x
12= -2x
divide -2 by 12.
-6 = x
The dimensions of the rectangular prism could be 3. 68 each for the length, width and height.
<h3>
How to determine the dimensions</h3>
The formula for determining the volume of a rectangular prism is expressed as;
Volume = length × width × height
From the information given, we have that the volume is 50 cubic meters
Let's assume that the three dimensions are x³
50 = x³
Make 'x' the subject by finding the cube root of both sides
∛x³ = ∛50
Remember that cube root cancels the cube, we then have;
x = ∛50
x = 3. 68 meters
Thus, the dimensions of the rectangular prism could be 3. 68 each for the length, width and height.

Answer:
$35.31
Step-by-step explanation:
In this question, we're trying to find the total cost of the pumpkins (including tax).
We know that Carter picked a $20 pumpkin, while Isabelle picked a $13 pumpkin.
We also know that the sales tax is 7%
To get your answer, we would add the prices of the pumpkin and find the tax price to get our final answer.
Find the total cost:
20 + 13 = 33
Since the sales tax is 7%, we would multiply 33 by 1.07:
33 · 1.07 = 35.31
Mrs. Stephan paid $35.31 for the pumpkins and sales tax.
