Answer : r = 7
Using transposition method taking 10 to LHS will be -10
= r = 17-10
r = 7
Verification :
17 = r + 10
17 = 7+10
17 = 17
HENCE, LHS=RHS

Hi there! Hopefully this helps!

----------------------------------------------------------------------------------------------

<h2>Answer: r = 7.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>

$17 = r + 10$

Swap sides so that all variable terms are on the left hand side.

$r + 10 = 17$

Subtract 10 from both sides.

$r = 17 - 10$

<h2>Subtract 10 from 17 to get, you guessed it, 7!</h2>

Answer for number 12

aalyn [17]

Answer:

12 a. 4605 feet 12 b. 1,459,063 square feet

Step-by-step explanation:

For the perimeter, we simply add the lengths of each of the 5 sides together (or multiply 5 times one side length).

P = 5(921)

P = 4605 feet

For the area, we will use composition...add the area of the triangle to the area of the trapezoid.

For the area of the triangle, the formula is

$A=\frac{1}{2}bh$ .

Filling in our values gives us

$A=\frac{1}{2}(1490)(541)$ and

A = 403,045 square feet.

Now for the trapezoid. The formula for a trapezoid is

$A=\frac{1}{2}(b_{1}+b_{2})(h)$

where the b's represent the bases and the h represents the height. Filling in our values gives us

$A=\frac{1}{2}(921+1490)(876)$

Work inside the parenthesis first:

$A=\frac{1}{2}(2411)(876)$ and

A = 1,056,018

Now we add those together to get that area of the Pentagon is 1,459,063 square feet

What are the answers to the questions below?

Tcecarenko [31]

Answer:

You have to follow PEMDAS or parenthesis, exponents, multiplication, division, addition, and subtraction. It's an order to solve equations. I listed the steps and the answers for you below :) I have throughly checked them so they should be correct! yw :D

Step-by-step explanation:

1. 5x + 4x - 6x = 24

9x - 6x = 24

3x = 24

24/3 = 8

x = 8

2. 8y + 5 - 4y + 1 = 46

8y - 4y = 4y

5 + 1 = 6

4y + 6 = 46

4y = 46 - 6

4y = 40

40/4 = 10

y = 10

3. 33 = 5 ( x + 8 ) + 3

33 = 5x + 40 + 3 (because we distributed)

33 = 5x + 43

5x + 43 = 33 (just rewriting it to make it easier)

5x = 33 - 43

5x = -10

-10/5 = -2

so x = - 2

4. 2m + 3 ( m - 8 ) = 1

2m + 3m - 24 = 1

we got 3m - 24 because we distributed the 3

5m - 24 = 1

5m = 25

25/5 = 5

m = 5

5. p + p - 2p + 4p = - 48

2p - 2p + 4p = - 48

4p = - 48

- 48 / 4 = - 12

p = - 12

6. 2 ( y + 5 ) + 3y = 25

2y + 10 + 3y = 25

5y + 10 = 25

5y = 25 - 10

5y = 15

15/5 = 3

y = 3

7. 1/4 h + 3/4 h + 1/2 h + 2 = 5

1/4 h + 3/4 h + 1/2 = 3/2 h

3/2 h + 2 = 5

3/2 h = 5 - 2

3/2 h = 3

h = 2

8. 60 = 4 ( k + 3 ) + 2 ( k - 3 )

60 = 4k + 12 + 2k - 6

4k + 12 + 2k - 6 = 60

6k + 6 = 60

6k = 60 - 6

6k = 54

k = 9

9. - 2 ( d + 1.4 ) - 1.8 = 20.6

-2d + - 2.8 - 1.8 = 20.6

-2d - 2.8 = 22.4

-2d = 25.2

d = - 12.6

10. 8 - 2 ( w + 4 ) = 10

8 + - 2 w + - 8 = 10

-2w + 9 + - 8 = 10

-2w = 10

10 / -2 = -5

w = -5
