Answer:

<em>8 14/45</em>

Step-by-step explanation:

First, place 8/9 anywhere there is a y:

6+8(8/9-3/5)

Next, do what is in the parenthesis. Make both fractions have the same denominator.

6+8(40/45-27/45)

And now subtract:

6+8(13/45)

Now, multiply 8 and 13/45:

6+ 104/45

Convert the fraction to a mixed fraction:

2 14/45

Finally, add 6:

8 14/45

Answer:

∠ 5 = 151°

Step-by-step explanation:

A linear pair are supplementary, that is sum to 180°

∠ 5 = 5 ∠ 6 + 6 , thus

∠ 5 + ∠ 6 = 180, that is

5 ∠ 6 + 6 + ∠ 6 = 180

6∠ 6 + 6 = 180 ( subtract 6 from both sides )

6 ∠ 6 = 174 ( divide both sides by 6 )

∠ 6 = 29°

Thus

∠ 5 = 180° - 29° = 151°

Equation that represents the depth Jalen can dive is,

S = 26M + 20

Here, S = Depth

M = Number of lessons

After 8 lessons he can dive,

S = 26×8 + 20

  = 228 feet

Therefore, Option (4) will be the answer.

The length of a rectangle is 4yd longer than its width.
Monica [59]

Answer:

Length= 19 yd

Width= 15 yd

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of all its sides.

Mathematically, it can be represented as below:

\boxed{\text{Perimeter of rectangle}=2\text{(length}+\text{width)}}

Define variables used:

Let the length and width of the rectangle be L and W yards respectively.

Form an equation:

Given that the length of the rectangle is 4 yards longer that the width,

L= W +4 -----(1)

Next, form another equation using information on the perimeter.

68= 2(L +W) -----(2)

Substitute equation (1) into (2):

68= 2(W +4 +W)

68= 2(2W +4)

Divide both sides by 2:

34= 2W +4

Subtract both sides by 4:

2W= 34 -4

2W= 30

Divide both sides by 2:

W= 30 ÷2

<u>W= 15</u>

Substitute W= 15 into (1):

L= 15 +4

<u>L= 19</u>

Therefore, the length and width of the rectangle is 19 and 15 yards respectively.
