Answer:

[See Below]

Step-by-step explanation:

✦ With this information we can make an equation to solve for y(years).

  • The tree is 4 \frac{1}{2} feet already.
  • It's expected to grow 1 \frac{3}{4} feet per year.
  • We are trying to figure our how many years until it's 40 feet.

✦ So the equation would be:

  • 40 ÷ 1 \frac{3}{4} =y

✦ Turn the fractions into a decimals to make it easier:

  • 1 \frac{3}{4} =1.75

✦ Now Solve by Dividing:

  • 40 ÷ 1.75=22.8571429

✦ Round:

  • 22.8571429 rounded to the nearest tenth =22.9

So your answer would be \bold2\bold2\bold.\bold9 years.

Answer:

Adult: 50 tickets

Child: 34 tickets

Step-by-step explanation:

Let a be the amount of adult tickets

Let c be the amount of child tickets

Equation:

a + c = 84

14a + 9c = 1,006

Step 1: Multiply a + c = 84 with -9, to canceled c.

-9 (a + c = 84)    →  -9a - 9c = -756

14a + 9c = 1006 → 14a + 9c = 1006

Step 2: Combined the 2 equation together, and solved it.

-9a - 9c = -756

<u>14a + 9c = 1006</u>

       <u> 5a</u> = <u>250</u>

        5        5

           a = 50

Step 3: Plug 50 into the one of the equation, and solved it.

a + c = 84 → 50 + c = 84

                  <u>-50         -50</u>

                            c = 34

Answer: Adult tickets (a) = 50 and Child tickets (c) = 34

To check the answer plug the two number into the equation ( Make sure to add 50 for a and 34 for c).

the length of a rectangle is 2 inches longer than twice its width. If the area of the rectangle is 24 square inches, what are th
gregori [183]

Answer:

The length is 8 inches and the width is 3 inches

Step-by-step explanation:

Let w represent the width.

The length can be represented by 2w + 2

Use the area formula, A = lw, and plug in the area and the expressions for the length and width:

A = lw

24 = (2w + 2)(w)

Simplify and solve for w:

24 = 2w² + 2w

2w² + 2w - 24

Divide everything by 2:

w² + w - 12

Factor:

(w + 4)(w - 3)

Set equal to 0 and solve for each factor:

w + 4 = 0

w = -4

w - 3 = 0

w = 3

Since the width cannot be negative, the width has to be 3.

Next, find the length by plugging in 3 as w:

2w + 2

2(3) + 2

= 8

So, the length is 8 inches and the width is 3 inches
