URGENT,PLEASE HELP!!!!!if -2 is the solution of the equation 2x+1-3c=2c+3x-7, find the value of c.​

Answer:

n=1

Step-by-step explanation:

(5 + 4n) + 11 = -5 (3 - 7n)

5+4n+11=−5(3−7n)

simplify

4n+16=−5(3−7n)

expand

4n+16=−15+35n

regroup

4n+16=35n−15

subtract

16=35n−15−4n

simplify

16=31n−15

add

16+15=31n

simplify

31=31n

n=1

Hope this helps :)

(pls mark brainliest)

Answer:

n=22

Step-by-step explanation:

8 (5 + 4n) + 11 = -5 (3 - 7n)

distribute

=> 40+32n+11=-15+45n

add like terms

=> 51+32n=-15+35n

subtract 35n on both sides and subtract 51 on both sides

32n-35n=-15-51

add like terms

-3n=-66

divide both sides by -3

n=22

Answer:

First one 5n-40 what does n so n=  8

The last one I see is d+15=30 so the d=15

Answer:

12:3/4, 3:3/16, 6:3/8

Step-by-step explanation:

12:3/4

by dividing that by 4, 3:3/16

by multiplying that by 2, 6:3/8

Answer:

2/3rds

Step-by-step explanation:

for 1 cup of flour you multiply 3/4th by 4 then devide by 3 giving you one cup of flour, now to keep it balanced you do the same to the milk, thus multiplying 1/2 by 4 then dividing it by three, which is 2, you then divide 2 by 3 giving you yours answer, 2/3rds

Answer:

A recipe calls for 1/2 cup of milk for every 3/4 cups of flour. How much milk is required for every cup of flour. *

Step-by-step explanation:

So for every  1/2 a cup is  3/4 cups of flour so if  you  need to know how much cups of flour  is  used for 1 total cup of  milk you have to  add you  multiply  it is optional if you add  put  the  two  fractions next to each other  you need to  add to the  side witch  the numbers are  3 so  3+3 is  6  so you got the answer just put  the number  4 under the  6 and  it will be 6/4  or you could say 1  2/4 or 1  1/2 .

Answer:

161 + 162 + 163 = 486

Step-by-step explanation:

(X) + (X + 1) + (X + 2) = 486

X + X + 1 + X + 2 = 486

3X + 3 = 486

3X + 3 - 3 = 486 - 3

3X = 483

3X/3 = 483/3

X = 161

Answer:

11

Step-by-step explanation:

The required distance left to the walk will be 11 km.

The percentage is defined as a ratio expressed as a fraction of 100.

Let the total distance of the walk would be x km

As per the given information, the required solution would be as:

⇒ 45% of x = 9

45%  is expressed as 45/100 in fractional form

⇒ (45/100)x = 9

45/100  is expressed as 0.45 in decimal form

⇒ 0.45x = 9

⇒ x = 9/0.45

⇒ x = 20

So the total distance of the walk is 20 km

Since he has already walked 9 km.

So, he has left to the distance of the walk = 20 - 9 = 11 km

Therefore, the required distance left to the walk will be 11 km.

Step-by-step explanation:

angleD=(7b+1)angle E=(2b+1)and angle F=(b+8)

Answer:

<E = 35

Step-by-step explanation:

7b + 1 + 2b + 1 + b + 8 = 180

combine like terms

7 + 2 + 1 = 10

10b

1 + 1 + 8 = 10

10b + 10 = 180

substract 10 from 180

= 170

10b = 170

170 divided by 10

= 17

now plug in for b for angle E

2 (17) + 1

= 35

Hence the number of places is 7

The scientific notation is  

=6.743*10^7

here is your answer...

hope it's help ful

Step-by-step explanation:

Using the formula:

C = 2πr

d = 2r

Solving for C

C = πd = π·22 = 69.11504mm.

So,

C = 69.11504mm

Answer:

(0,2)

x=0

y=2

Step-by-step explanation:

We know that y=x+2

This means that we can subsitute this for y into the second equation

3x+3(x+2)=6

This is easy to solve

3x+3x+6=6

6x=0

x=0

We can then use this value for x in the second equation

y=0+2

y=2

I doubled checked this answer on desmos and my math is correct

Answer:

Answer:

(0,2)

x=0

y=2

Step-by-step explanation:

We know that y=x+2

This means that we can subsitute this for y into the second equation

3x+3(x+2)=6

This is easy to solve

Step 1:

3x + 3x + 6 = 6

Step 2:

6x=0

6      6

x=0

Then you should substitute y =x + 2 with the given solution from the first equation, x = 0

y=0 + 2

y=2

Your answer should be, x =0 and y = 2 or (0,2)
