Answer:
Bottom left = 8
Top right = 15
Middle right = 25
Step-by-step explanation:
Total = 40
3 + 5 = 8
40 / 8 = 5
1 part = 5
5 x 3 = 15
5² = 25
Convert to a common denominator. Let's use 56. 3/8 = 21/56 and 9/28 = 18/56.
21/56 + 18/56 = 39/56
answer is 39/56

Answer:
622.27
Step-by-step explanation:
- $87.45 + (- $24.76) + (-17.29) = $-129.5
$143.87 + $348.90 = $492.77
492.77 - (-129.5) = 622.27
Answer:6/25
Step-by-step explanation:
Y varies inversely as x²
Y =k/x²
Y= 6, x = 30
Substitute the value of y and x
6 = k/30²
Make k the subject of the formula
k = 6/900
k =1/150
The equation connecting Y and x is
Y = x²/150
When x = 6
Y= 6²/150
Y= 36/150
Y= 6/25
