The cost of a brush, a sketchbook, and a paint set will be $ 2.38, $ 14.3, and $ 19.067 respectively.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Genevieve brought $35.75 to the art supply store.

She bought a brush, a sketchbook, and a paint set.

Let x be the cost of the paint set.

The sketchbook cost 3/4 the cost of the paint set. Then the cost of the sketchbook will be

\rightarrow \rm \dfrac{3x}{4}

The brush was 1/6 as much as the sketchbook. Then the cost of the brush will be

\rightarrow \rm \dfrac{3x}{4} \times \dfrac{1}{6}=\dfrac{x}{8}

Then the value of the paint set will be

\begin{aligned} \dfrac{3x}{4} +\dfrac{x}{8} + x &= 35.75\\\\\dfrac{15}{8}x &= 35.75\\\\15x &= 286\\\\x &= \$ 19.067 \end{aligned}

Then the cost of the sketchbook will be

→ 3 × 19.067 / 4 = $ 14.3

Then the cost of the brush will be

→ $ 2.38

Elenna [48]

Answer:

A baseball player hit 73 home runs in a season.

Of the 73 home​ runs, 25 went to right​ field, 25 went to right center​ field, 8 went to center​ field, 10 went to left center​ field, and 5 went to left field.​

(a)  the probability that a randomly selected home run was hit to left center ​field = \frac{10}{73}=0.1369 = 13.69%

(B) Since the probability of an unusual event is 0, it was possible for this player to hit a home run to left center ​field.

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Marina86 [1]

Given:

Jake bought 3 drawing pens for $8.07.

Each pen costs the same amount.

To find:

How much did he spend for one pen?

Solution:

Let x be the cost of each pen. Then

Cost of three pens = 3x

Jake bought 3 drawing pens for $8.07.

3x=8.07

Divide both sides by 3.

x=\dfrac{8.07}{3}

x=2.69

Therefore, he spend $2.69 for one pen.
