Answer:
13 , 35
Step-by-step explanation:
Let's call one of the number x and the other y
x + y = 47
x - y = 21 and x = 21 + y if we use this expression in the first equation instead of x we can find the value of y
x + y = 47 ➡ y + y + 21 = 47 add like terms
2y +21 = 47
2y = 47 - 21
2y = 26
y = 13 the value of first number is 13
x + y = 47 we know y is 13 so we can replace it
x + 13 = 47
x = 35
Answer: 80 items
Step-by-step explanation:
The equation x=0.7x + 24 can be rewritten as 1x = 0.7x + 24 because the is a number on in front of any variable.
1x = 0.7x + 24 subtract 0.7 from both sides
-0.7 -0.7
0.3x = 24
x = 80
Answer:
After population (A) = 62,902 (Approx)
Step-by-step explanation:
Given:
Current population (P) = 19613
Number of years (n) = 2020 - 2000 = 20 year
Rate of growth (r) = 6% = 0.06
Find:
After population (A)
Computation:
The negative of it would be the positive so the answer is 1/4
