I need help please I have to finish this

4vir4ik [10]

Answer: x=4

Step-by-step explanation:

We know that line segment AC= AB + BC

we also know that AB= 3x+8 and BC= 2x-5

by substituting these, we get AC= (3x+8)+(2x-5)

AC is given as being 23, so we know that

23= (3x+8)+(2x-5)

by combining like terms, we get that

5x+3=23

simplify this to get that x=4

A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

Soloha48 [4]

Answer:

72 cubic inches

Step-by-step explanation:

Volume of cone = $\frac{1}{3}\pi r^{2} h$ --1

Volume of cylinder = $\pi r^{2} h$ --2

We are given that a cylinder should fit exactly inside the cone

On comparing 1 and 2 we can see:

$\text{Volume of cone}= \frac{1}{3} \text{Volume of cylinder}$

Since we are given the volume of cone is 24 cubic inches .

So, $24= \frac{1}{3} \text{Volume of cylinder}$

$24 \times 3= \text{Volume of cylinder}$

$72= \text{Volume of cylinder}$

Hence the volume of cylinder is 72 cubic inches

Option D is correct.

Hamburgers cost $3 each and hot dogs cost $2 each write an equation that represents the total cost, T, of b, hamburgers and, h,

bonufazy [111]

Answer:

$3h+$2h=T

Step-by-step explanation:

Since we don't know how many hot dogs(h) or hamburgers(h) they will buy, you just need to use the variables and multiply by how much each one costs and then add them to get the Total (T).
