Step-by-step explanation:
(2x-5) = 3(4+x/2) then solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x=34
Checking the left side, (2x-5) = 2(34) - 5 = 63.
Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.

The net of a cube is shown below. If the surface area of the net is 294 in^2 , then what is the length of each side of the cube?
Answer:
7 in
Step-by-step explanation:
294:6=49
[tex]\sqrt{49}=7 in[/tex]
The length of each side of the cube is 7 inches.
What is surface area of a cube?The surface area of the cube all six faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added six times to itself. The formula to find the surface area of a cube is 6a², where a is edge.
Given that, the surface area of a cube is 294 square inches.
Now, 6a²=294
a²=294/6
a²=49
a=7 inches
Therefore, the length of each side of the cube is 7 inches.

Step-by-step explanation:
If the midpoints of the sides of ∆EFG shown below were connected with line segments, what would be the perimeter of the resulting triangle? Explain how you arrived at your answer. *
Answer:
17.5
Step-by-step explanation:
I beleive since we are connecting midpoints you divide each side by 2 and add them all up to get the perimeter of the smaller triangle made with the ratio of 1:2
The midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Given
If the midpoints of the sides of ∆EFG shown below were connected with line segments.
Then the sides of the triangle get half.
Then the perimeter will be of a new triangle will be
[tex]\rm Perimeter = \dfrac{8}{2} + \dfrac{15}{2} +\dfrac{12}{2}\\\\Perimeter = 17.5[/tex]
Thus, the midpoints of the sides of ∆EFG are connected with line segments, then the perimeter of that triangle is 15.5 cm.

What is the simple ratio of 32kg to 108kg
Answer:
1 : 3.375
Step-by-step explanation:
divide both sides by 32 to get the above answer
The simple ratio of 32kg to 108kg is 8 : 27.
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
Given, Two similar quantities one weighs 32 kgs and the other weighs
108 kgs.
Therefore, The ratio between them is 32 : 108.
= 16 : 54.
= 8 : 27.
