Answer:

The simplest form is 6m+91.

Step-by-step explanation:

Consider the given information.

-10(-3m-10)-3(-8m+3)

First, remove the parenthesis by multiplying -10 and -3 inside the parenthesis.

30m+100-24m-9

Now, rearrange the like terms.

30m-24m+100-9

Combine the like terms.

6m+91

Hence, the simplest form is 6m+91.

Peter, henry and john shared $345 between them. Peter received $45, henry received $75 and john received the rest.
melomori [17]

Answer:

Step-by-step explanation:

Let J = John's share ($)

     P = Peter's share ($)

     H = Henry's share ($)

 

1) H = P + 80

 

2) J/P = 6/3 = 2

 

3) P/H = 3/5  

 

Substitute equation 1) into equation 3)

 

P/(P + 80) = 3/5            (multiply both sides by (P + 80)

 

P = (3/5)*(P + 80)         (multiply both sides by 5)

 

5*P = 3*P + 240

 

2*P = 240

 

P = 240/2 = $120

 

Substitute P value into equation 2)

 

J/P = 2  or

 

J = 2*P = 2*$120 = $240

 

John received $240

If a and b are positive integers and 22a(22b)=16, what is the value of a+b?
Kryger [21]
Given that:
<span>22a(22b)=16
484ab=16
thus
ab=16/484
ab=4/121
thus given that 
ab=4/121
then
a=4 and b=1/121
hence
4+1/121
=4 1/121</span>

What is the next number and why ? 1,3,11,35,99,_
Vladimir79 [104]

Answer: 241

Step-by-step explanation:

This is a simple problem when using Pascal's triangle. First you look at 1 - 3, what is the difference in these 2 numbers? Its 2, then you look at 3 and 11, the difference is 8, then 11 and 35, the difference is 24. If you keep doing this you get; 2 8 24 64 142. Next you find out how these numbers are different. In the end you keep doing this until you get to the triangles point or the differences converge.

                                          1      3      11      35     99      <u>241</u>

                                             2      8     24       64    142

                                                6      16      40      78

                                                     10     24      38

                                                          14       14

In the end we get 14 but there is no difference in the numbers so we cant go any farther. Hope this helps!
