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

Answers

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

angle D=(7b+1) angle E=(2b+1) and angle F=(b+8) what is the measure of angle E

Answers

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

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 .

How do I solve this with substitution, can you please put the work and steps. (x,y)
y=x+2
3x+3y=6

Answers

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)
