Answer:

The correct answer is y/2

Step-by-step explanation:

It is given that,

(x + 3)/ 3 = (y + 2)/ 2

<u>To find x/3</u>

(x + 3)/ 3 = (y + 2)/ 2

⇒ x/3 + 3/3 = (y + 2)/2

x/3 + 1 = (y + 2)/2

x/3 = (y + 2)/2 - 1

x/3 = (y + 2)/2 -2/2

x/3 = (y + 2 - 2)/2

x/3 = y/2

Therefore the correct answer is x/3 = y/2

Amanda [17]

Answer: 6,160,000 db

Step-by-step explanation:

The sound of a jet engine is 70,000 times louder than that of a lawn mower.

Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:

= Sound of lawnmower * 70,000

= 88 * 70,000

= 6,160,000 db

What is the area of this?

Vanyuwa [196]

$area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2}$

$area = \frac{1}{2} bh \\ area = \frac{1}{2} (6)(4) \\ area = \frac{1}{2} (24) \\ area = 12 {feet}^{2}$

total area = 45 + 12

total area = 57 feet²

A textbook store sold a combined total of 260 chemistry and physics textbooks in a week. The number of chemistry books sold was

Lynna [10]

Let:

x = Chemistry textbooks sold

y = Physics textbooks sold

The textbook store sold a combined total of 260, so:

$x+y=260$

The number of chemistry books sold was three times the number of physics textbooks sold, so:

$x=3y$

Let:

$\begin{gathered} x+y=260_{\text{ }}(1) \\ x=3y_{\text{ }}(2) \end{gathered}$

Replace (2) into (1):

$\begin{gathered} 3y+y=260 \\ 4y=260 \\ y=\frac{260}{4} \\ y=65 \end{gathered}$

Replace the value of y into (2):

$\begin{gathered} x=3(65) \\ x=195 \end{gathered}$
