Answer:

Similar triangles states the length of the  corresponding sides are in proportion.

In a given similar triangles:

Labelled the diagram:

Triangle BAC and triangle DAC are similar.

then;

Corresponding sides:

\frac{AB}{AD} = \frac{BC}{DC}

AB = x units , BC = 5 units, AD = 15 units and DC = BD-BC = 8-5 = 3 units

\frac{x}{15} = \frac{5}{3}

By cross multiply we get;

3x = 15 \cdot 5

Simplify:

3x = 75

Divide both sides by 3 we get;

\frac{3x}{3}=\frac{75}{3}

Simplify:

x = 25 units

Therefore, the value of x is 25 units.

A store is selling five cans of tomato sauce for $5.25. What is the unit price? unit price = total price ÷ number of units per p
aleksklad [387]

Answer: Option A

P = \$\ 1.05

Step-by-step explanation:

If we have 5 cans of ketchup they cost $ 5.25. Then the unit price of cans is what each can costs individually.

The unit price should then be less than $ 5.25, and that is the price for 5 cans and we want to know the price for just one can of ketchup.

Then to calculate the price of each can divide the price of the 5 cans by 5.

P = \frac{5.25}{5}

P = \$\ 1.05
