Answer:
W = (P-2L)/2
Step-by-step explanation:
Isolate W
P = 2L + 2W
subtract 2L from each side
P - 2L = 2W
divide each side by 2
(P-2L)/2 = W
For this case, the first thing we must do is define a variable.
We have then:
n: number of days.
We now write the explicit formula that represents the problem.
We have then:
an = 4n + 15
Where,
15: crunches the first day
4: increase the number 4 each day
Answer:
An explicit formula for the number of crunches Abbie will do on day n is:
an = 4n + 15
Answer:
Step-by-step explanation:
you could think that 22% is close to 25% , so one forth of it, 1/4
78 percent is close to 80
1/4 of 80 is 20
actually 78*22/100=17.16
Answer:
4/5 times 40 = 32
1/6 times 48= 8
5/8 times 64= 40
