Answer:
7. m and n = √8
8. a and b = √2
9 x and y = √1/8
10. x and y =5/√2
11. x and y = 3/√2
12. x and y = 9/√2
Step-by-step explanation:
Lets first numbers is x, second is (x+2), third is x+4
sum is x+(x+2)+(x+4)=87
3x+6=87
3x=81
x=27
Answer: smallest number is 27
Answer:
Brand A is the better buy with unit rate $4/cup.
Step-by-step explanation:
Given:
Brand A 33 fluid ounce bottle = $16.50
Brand B 1 cup = $4.80
We need to find the unit cost and find which is the better buy.
Solution:
For Brand A;
33 fluid ounce = $16.50
1 fluid ounce = Cost for 1 fluid ounce
By using Unitary method we get;
Cost for 1 fluid ounce = 
Now we know that;
1 cup = 8 fluid ounce.
1 fluid ounce = $0.5
8 fluid ounce = Cost for 8 fluid ounce of olive oil.
Again By using Unitary method we get;
Cost for 8 fluid ounce of olive oil = 
Hence Brand A 1 cup of olive oil cost $4.
For Brand B;
Given:
1 cup of olive oil =$4.80
Hence Brand B 1 cup of olive oil cost $4.8.
By Comparing both brands we can see that per unit cost of Brand A is less than Brand B.
Hence Brand A is the better buy.
Answer:

Step-by-step explanation:
After the 5% raise, her weekly pay was ...
$550 × 1.05 = $577.50
If she works 35 hours for that pay, her hourly rate is
$577.50/35 = $16.50
Then, working 30 hours, her weekly pay will be ...
30 × $16.50 = $495.00
