For the first one a = 2.5. For the second one m = 4. For the third one m = -4
Answer:
12
Step-by-step explanation:
the number is 96
hence,
25% of 96=
25/100*96/1
=24
50% of 24=
50/100*24/1=
12
it also possible that you're to sum them,but since you were not asked for the sum of the number the answer is 12.
Let's work this problem out!
First: 5(x) - 26 - x + 50 = ?
Second: 4(x) - 76 = ?
Third: 4 = ?
↑
(Solve Step 3)
Fourth: x - 19 = 0
↑
(Add the number 19 to each of your sides for Step 4)
Finally we get to your answer
19 + 0 = 19 ; 19 - 19 = 0
So, therefore the value of "x" is 19
Is this 13 and 34 ? or 1,3,3,4?
Life expectancy of dollar bill = d
life expectancy of coin = c
d = 1/20 c
substitute value in for c (30)
d = 1/20 * 30
d = 30/20
d = 1.5
life expectancy of a dollar bill = 1.5 years
