Answer:

m=10

Step-by-step explanation:

9(m+5)−3(m−2)=8m+31

Step 1: Simplify both sides of the equation.

9(m+5)−3(m−2)=8m+31

9m+45+−3m+6=8m+31

(9m+−3m)+(45+6)=8m+31(Combine Like Terms)

6m+51=8m+31

Step 2: Subtract 8m from both sides.

6m+51−8m=8m+31−8m

−2m+51=31

Step 3: Subtract 51 from both sides.

−2m+51−51=31−51

−2m=−20

Step 4: Divide both sides by -2.

m=10

Hope this helps girly!!

No she didn't write the decimal correctly. This is because 50 as a decimal is 0.50 and not 0.05

The last one Please answer asap im still crying
Anna007 [38]

Answer:

He has 12 ten dollar bills

Step-by-step explanation:

Let t = number of 10 dollar bills

f = number of fifty dollar bills

t+f = 25  since he has 25 bills

solving for f

f = 25 -t

Then we know he has 770 dollars

10t+50f = 770

Using f = 25-t in the above equation

10t + 50 ( 25-t) = 770

Distribute

10t+ 1250 - 50t = 770

Combine like terms

-40t+1250 = 770

subtract 1250 from each side

-40t - 1250-1250 = 770-1250

-40t = -480

divide each side by -40

-40t/-40 = -480/-40

t =12

He has 12 ten dollar bills

in a AP the first term is 8,nth term is 33 and sum to first n terms is 123.Find n and common difference​
mixer [17]

Answer:

Step-by-step explanation:

First I want to set up some variables.

S = sum

n = final term

ax = xth term, so a1 is the first term and an is the last one

d = common difference.

There are two formulas to find the sum, if you don't get how they were gotten I'd be happy to explain.

S = (n/2)(a1+an) = (n/2)(2a1+(n-1)d)

So, to find n we use the first one.

S = (n/2)(a1+an)

123 = (n/2)(8+33)

123 = (n/2)41

3 = n/2

6 = n

Now we can find d with the other one

S = (n/2)(2a1+(n-1)d)

123 = (6/2)(2*8+(6-1)d)

123 = 3(16+5d)

41 = 16+5d

25 = 5d

5 = d

so there are six terms and the common  difference is 5.
