Answer:
the two numbers are 19 and 6
Step-by-step explanation:
so we know that there are two numbers that added together give us 25
x+x=25
one of the numbers is twice the amount of the second plus 7
(2x+7)+x=25
simplify 2x+7+x
3x+7=25
subtract 7 from both sides
3x=18
divide 3 by both sides
x=6
and there is your answer.
Answer:
You can't solve this because it's alreadying in simpalest form.
Step-by-step explanation:
Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.
Step 2: Multiply both top and bottom by that number.
Step 3. Then write down just the top number, putting the decimal point in the correct spot (one space from the right hand side for every zero in the bottom number)
C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
