Answer:

Let's solve for f.

fx=5x−3

Step 1: Divide both sides by x.

5x−3

Let's solve for x.

fx=5x−3

Step 1: Add -5x to both sides.

fx+−5x=5x−3+−5x

fx−5x=−3

Step 2: Factor out variable x.

x(f−5)=−3

Step 3: Divide both sides by f-5.

x(f−5)

f−5

−3

f−5

−3

f−5

Answer:

−3

f−5

Tessa bought stock in a restaurant for $278.00. Her stock is now worth $339.16. What is the percentage increase of the value of

Natasha2012 [34]

The percentage increase of the value of Tessa's stock is 22%

Step-by-step explanation:

The percentage of increase = $\frac{New-old}{old}$ × 100%, where:

New: is the value after increasing
Old: is the value before increasing

Tessa bought stock in a restaurant for $278.00.

Her stock is now worth $339.16

We need to find the percentage of increase of the value of

Tessa's stock

∵ The initial value of the stock = $278.00

∴ The value of the stock after increasing = $339.16

- Substitute these values in the rule above

∴ The percentage of increasing = $\frac{339.16-278}{278}$ × 100%

∴ The percentage of increasing = 0.22 × 100%

∴ The percentage of increasing = 22%

The percentage increase of the value of Tessa's stock is 22%

The ornament below is composed of two congruent square pyramids. Each square pyramid has base side lengths of 2 inches and a hei

kondor19780726 [428]

Answer:

The volume of the ornament is $6\frac{2}{3}\ in^{3}$

Step-by-step explanation:

we know that

The volume of the ornament is equal to the sum of the volume of the two congruent square pyramids

$V=2[\frac{1}{3}b^{2} h]$

we have

$b=2\ in$

$h=2.5\ in$

substitute

$V=2[\frac{1}{3}(2)^{2} (2.5)]$

$V=\frac{20}{3}\ in^{3}$

Convert to mixed number

$\frac{20}{3}=\frac{18}{3}+\frac{2}{3}=6\frac{2}{3}\ in^{3}$
