(2x-4) / 5 = x + 4.  Mult. both sides by 5 to eliminate the fraction on the left side:

2x-4=5x + 20

Combining like terms, 3x = -24, and so x = -8

A. What is the volume, in cubic feet, of the box in the diagram?
Allisa [31]

Volume is a three-dimensional scalar quantity. The number of boxes that can fit in the cargo hold of the truck is 54.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

The volume of the box = Volume of the cube = a³ = (2.50)³ = 15.625 ft³

The volume of cargo hold = 7.50 × 7.50 × 15 = 843.75 ft³

Now, the number of boxes that can fit in the cargo hold of the truck will be,

Number of boxes = (Volume of truck container)/(Volume of box)

                              = 843.75/15.625

                              = 54

Hence, the number of boxes that can fit in the cargo hold of the truck is 54.

Two sides of a triangle are 8cm and 12cm. Which of the following CANNOT be the measure of the third side,
blondinia [14]

Answer:

4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.

Answer=8

b = 73


choice b


15. That's intersecting chords so the product of the segment lengths are equal:


5(22)=10 x


x = 5(22)/10 = 11


choice a


16. Intersecting tangent and secant;


x^2 = 5(19)


x = \sqrt{95} \approx 9.75


Choice a

Twelve friends came to Guy's birthday party. He received seven gifts and a total of $95 in cash for his birthday. He buys an air
anastassius [24]
Hey!

Ignore the birthday party stuff and go to 95 first. Subtract 9 from 95 you get the answer 86. Next you need to find how many times 8 goes into 86. 86/8 which is 10 with a remainder of 6. Therefore, Guy can donate to 6 animal shelter. I hope this helps with future problems.
