Answer: divide by 9x on both sides

Step-by-step explanation: first + 23 to 49, that cancels out the (-23)

you now have 72

next you divide by 9x on both sides, this cancels out the 9 and you get x by itself, and then 72/9

you divide 72 by 9 and you get x=8

Step-by-step explanation:

The first step is to find out what times 9 - 23 = 49 the first step would be to add 49 + 23 and that would get 72 so then you find that x would = 8 so the second step should be to put the problem together so 72 - 23 = 49. so basically x would equal 8.

A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Anoth
shutvik [7]

Answer:

$12

Step-by-step explanation:

assuming that the cost of delivery is constant irrespective of the number ordered

Let the cost of sandwich be x

First office

$33=4x+c where c is the cost of delivery

Second office

$61=8x+c

These two are simultaneous equation. Subtracting the equation of first office from the second office we obtain

4x=28

Therefore, x=28/4=7

The cost of delivery is 33-(4*7)=33-28=5

Therefore, one sandwich plus delivery costs 7+5=$12

Alexis put $2000 in savings account. After 4 years, she had $2543 in the account. What rate of interest did she earn?
Marizza181 [45]

Answer:

A

Step-by-step explanation:

Hihi. So, this is a nice application of interest rates as well as properties of exponentials/logarithms. As you know, the basic equation for interest rates is A= Pe^(rt) where A is your final amount, P is your initial, r is your rate of interest, and t is the time the money was accumulating interest. After cleaning up, you get in a situation due to you having e still lying around. Luckily, if you take the natural log of e, all you have left behind is the previous exponent. Thus, you can take the natural log of both sides, divide by 4, and then simplify to see that your final interest rate is ~6%
