Let 1st number be = x
Thus second number = x - 4
Now
(x) + (x - 4) = 72
2x - 4 = 72
2x = 76
x = 38
1st number is 38 thus 2nd number is (38 - 4) = 34

5.4+n
Answer:
R = 30
Step-by-step explanation:
Given y is directly proportional to R² then the equation relating them is
y = kR² ← k is the constant of proportion
To find k use the condition when R = 4, y = 24, then
24 = k × 4² = 16k ( divide both sides by 16 )
1.5 = k
y = 1.5R² ← equation of proportion
When y = 1350 , then
1350 = 1.5R² ( divide both sides by 1.5 )
900 = R² ( take the square root of both sides )
= R , that is
R = 30
Answer: The equation is <em>s</em> = 350 + 60<em>s</em>, and given this equation, we can determine that the total savings after eleven weeks is $1,010.
