Answer:

5) x = -1

6) x = 2

Step-by-step explanation:

5) 5 + 2x + 6 = x + 10

   2x + 11 = x + 10

   2x + 1 = x

   1 = -x

   -1 = x

6) (9x + 7) + (-3x + 20) = 39

    6x + 27 = 39

    6x = 12

     x = 2

Answer:

For question 5, x= -1

Step-by-step explanation:

Segment Addition Postulate = ab+bc=ac

For Question 5,

(a)     +    (b)  = (c)  

5+2x  +   6    = x+10

5+2x+6=x+10

<u>To solve that, </u>

5+2x+6=x+10

<u>Add 5+6 </u>

11+2x=x+10

<u>Subtract 11 from both sides</u>

2x= x-1

x-1=2x

Please help me with numbers 1 &amp; 2. Please show work, thank you.

1.) Jarvis lives 3 miles away from Cassidy and Theo lives 6 miles away.
(if Jarvis lives 3 miles away from Cassidy and Theo is twice as far from Jarvis, Theo would be twice as many miles away from Cassidy than Jarvis; 3 times 2 is 6; 3+6+=9)
2.) Jorge's watering can can hold 8 cups of water.
(Older brother's can hold 16 cups; 8+8+16= 32; there are 32 cups in 2 gallons)

Please come answer ASAP!!!<br> 5 - n divided by 3 = 4 what is the value of n?
Varvara68 [4.7K]

Hey there!

The equation we have been given is 5 - n/3 = -4.

Let's start by subtracting 5 from each side.

-n/3 = -9

Multiply each side by 3.

-n = -27

Multiply each side by -1.

n = 27

Check our answer.

5 - 27/3 = -4

5 - 9 = -4

-4 = -4

The value of n is 27.

Hope this helps!
