Answer:
x+(x+4)=52
Step-by-step explanation:
Let's name the smaller number x.
The greater number would then be (x+4).
<em>The sum of two numbers means we are adding them together.</em>
<u>The equation we could then set up would be:</u>
x+(x+4)=52
<em>Now we can solve the equation to find the two numbers if needed.</em>
<u>Here is how:</u>
x+x+4=52
Combine like terms.
2x+4=52
Subtract 4 from both sides.
2x=48
Divide both sides by 2
x=24
The smaller number is 24.
24+4=28
The larger number is 28.
Answer:
3 Years
Step-by-step explanation:
7000*22% = 1540
4620/1540 = 3
1540 = the yearly interest
so it will take 3 years of $1540 of interest to get $4620.
Normally you would also have to take into account the interest plus the base varible but since it specifically says 7000 it makes it a simple problem.
hope this helped
The order does not matter (A,B,C same as B,C,A) so it's a combination 28 choose 5.
