Answer:
x = 8
Step-by-step explanation:
Step 1 : Simplify the equation
3(x-5) + 7x = 65
3x - 15 + 7x = 65
Step 2 : Make x the subject
3x + 7x = 65 + 15
10x = 80
x = 80/10
x = 8

Using whole numbers, fractions and decimals, the following equations have the sum of 10.
1. 6 + 3 + 1 = 10
2. 2.25 + 4.25 + 3.50 = 10
3. 7/2 + 5/2 + 8/2 = 10
4. 25/5 + 15/5 + 10/5 = 10
5. 6 + 2. 25 + 1.75 =10
6. 3.26 + 4. 52 + 2.22 = 10
7. 5+ 3 + 2 = 10
8. 3/4 + 4/2 =10
Answer:
x=0
Step-by-step explanation:
-8x + 2(4x + 2) = 4
Use distributive property to get rid of the parentheses
-8x + 8x + 4 = 4
Add the like terms.
x + 4 = 4
Subtract both sides by four.
x = 0
Answer: The accident proportion differ between the two age groups is 0.11.
Step-by-step explanation:
Since we have given that
Number of clients under 18 years of age = 500
Number of clients had had an accident = 180
Proportion of client had an accident = 
Number of clients aged 18 and older = 600
Number of clients had had an accident = 150
Proportion of client had an accident = 
So, According to question, we get that
Difference between the two age groups proportions would be :

Hence, the accident proportion differ between the two age groups is 0.11.
