Answer:

Solved for y: $y = 4/3 + 5/6x$

Solved for x: $x = 6/5y - 8/5$

Step-by-step explanation:

Solving for y

Step 1: Subtract 5x from both sides

$5x - 6y - 5x = -8 - 5x$

$-6y = -8 - 5x$

Step 2: Divide both sides by -6

$-6y / -6 = (-8 - 5x) / -6$

$y = 4/3 + 5/6x$

Solving for x

Step 3: Add 6y to both sides

$5x - 6y + 6y = -8 + 6y$

$5x = 6y - 8$

Step 4: Divide both sides by 5

$5x / 5 = (6y - 8) / 5$

$x = 6/5y - 8/5$

Answer:

1- A. 3(10÷2) +2·7

2- A. 0.4

3- B. -2.8

4- C. n·6 - 12 = 60

Step-by-step explanation:

Heres the work in case teachers ask:

1. The given expression evaluates to ...

30÷2 + 2·7 = 15 + 14 = 29

A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true

B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29

C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29

D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29

2. You can divide the equation by 10 to find the appropriate value of x.

4/10 = 10x/10 = x . . . . . 4/10 matches choice A

3. The expression simplifies to ...

7.5 -10.3 = -2.8 . . . . . . matches choice B

4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...

n×6 - 12 = 60 . . . . . . . . matches selection C

Hopefully this helped, if not HMU and I will try my best to get you a better answer!

Have a great day! :)

And if u need help with anything, HMU and I got you! -No points needed :)

the length of a rectangle is 3 feet more than twice the width. if the width is increased by four feet the perimeter of the new r

densk [106]

Answer:

The area of the original rectangle = 189 sq ft.

Step-by-step explanation:

Let, the width of the rectangle = m feet

So, the length of the rectangle = (2 m + 3) ft

Now, new width w' = (m + 4)

Perimeter of new rectangle (P') = 68 ft

Perimeter of a rectangle = 2 (LENGTH + WIDTH)

⇒68 ft = 2( L + W')

or, 68 ft = 2 [( 2m + 3) + (m + 4)]

or, 2 (3m + 7) = 68

or, 3m + 7 = 68/2 = 34

⇒ 3m = 34 - 7 = 27

⇒ m = 27/3 = 9

or, m = 9 ft

Hence, the original width of the rectangle = 9 ft

Original Length of the rectangle = 2m + 3 = 2(9) + 3 = 21 ft

Now, Area of the Rectangle = LENGTH X WIDTH

= 21 ft x 9 ft = 189 sq ft

Hence,the area of the original rectangle = 189 sq ft.

9/50=x/300
you would have to cross multiply. 2,700=50x
then you want x by itself so you divide each side by 50.
