Answer:
5.7a - 18.2b
Step-by-step explanation:
<u>Step 1: Write the equation</u>
(12.2a + 9.7b) – (18.1b – 0.2a) – (6.7a + 6.8b)
<u>Step 2: Open all brackets</u>
12.2a + 9.7b - 18.1b + 0.2a - 6.7a - 6.8b
<u>Step 3: Arrange all 'a' together and all 'b' together</u>
12.2a + 0.2a - 6.7a + 9.7b - 18.1b - 6.8b
<u>Step 4: Simplify</u>
5.7a - 18.2b

Step-by-step explanation:
How many do you go up over how many you go over.
Answer:
a) 1/2
b) 9/40
Step-by-step explanation:
Given
Total number of families living in Willbrook Farms Development = 20
Number of families preparing their own federal income taxes for last year = 10
Number of families for which taxes were prepared by a local professional = 7
Number of families for which taxes were prepared by H&R Block = 3
a) Probability of selecting a family that prepared their own taxes = 10/20 = 1/2
b) The probability of selecting two families, both of which prepared their own taxes
10/20 * 9/20 = 9/40
The value of x when y is 14.4 is 5.
It is given that
y ∝ 1/x
y = k/x....(1)
Where k is a constant of proportionality
<h3>What is the constant of proportionality?</h3>
The constant of proportionality is the ratio that relates two given values.
When y =6, x=12
Means, 6 = k/12
k = 72
Putting the value of k in equation (1)
y = 72/ x
14.4 = 72/ x
x = 5
Therefore, The value of x when y is 14.4 is 5.
