(x (15))/100 = 8
x(15) = 800
x = 800/15 = 53,3333 ( just take 53 )
Answer:
12
Step-by-step explanation:
Given that
Current count of pushups = 8
Number of increase in pushups each day = 2
The desired pushup goal on daily basis = 30
Days require = x= ?
as we can conclude the number of pushups would increase by following sequence
8, 10, 12, 14, 16, ......30
Now as we can be the number of pushups by a constant number each day it means this sequence is arithmetic.
First term of our sequence is X1 and the final term is Xn, and the difference between two consecutive terms (Common Difference) is 2.
So
X1 = 8
Xn = 30
d = 2
Using the formula of nth term for arithmetic sequence
Xn = X1 + (n-1)d
Substituting the values
30 = 8 + (n-1)2
30-8 = (n-1)2
22 = 2n -2
22+2 = 2n
2n = 24
n = 24/2
n = 12
So, it means on the 12th day he will have to do 30 pushups if he starts from 8 and increase 2 pushups each day.

Answer:
larger number = 16
smaller number = 12
Step-by-step explanation:
let the larger number = x
let the smaller number = y
Difference between the two numbers is 4:
x - y = 4
The larger number is 8 less than twice the smaller number
x = 2y - 8
Rewrite x - y = 4 to make x the subject:
x = 4 + y
Substitute x = 4 + y into x = 2y - 8 and solve for y:
4 + y = 2y - 8
4 + 8 = 2y - y
12 = y
Now substitute the found value for y into x - y = 4 and solve for x:
x - 12 = 4
x = 4 + 12 = 16
