Answer: You will need 3.5lbs of the cheaper candy
and 5 lbs of the expensive candy.
Step-by-step explanation:
Let x represent the number of pounds of the cheaper candy that you would need.
Let y represent the number of pounds of the expensive candy that you would need.
You would like to have 8.5 lbs of a candy mixture. It means that
x + y = 8.5
You have one type of candy that sells for $1.70/lb and another type of candy that sells for $3.40/lb. The candy mixture would sell for $2.70/lb. It means that the total cost of the mixture would be 8.5 × 2.7 = $22.95. The expression would be
1.7x + 3.4y = 22.95- - - - - - - - - - - 1
Substituting x = 8.5 - y into equation 1, it becomes
1.7(8.5 - y) + 3.4y = 22.95
14.45 - 1.7y + 3.4y = 22.95
- 1.7y + 3.4y = 22.95 - 14.45
1.7y = 8.5
y = 8.5/1.7
y = 5
x = 8.5 - y = 8.5 - 5
x = 3.5

12.3
Step-by-step explanation:
271-119= 152
get square root of 152
12.3x12.3=152
Answer:
Step-by-step explanation:
The order of a succession is a way that the terms (the first, the second, the third, etc.) can be distinguished according to a certain formation law or order criterion.
Example:
a¹/a²/a³/a⁴ And successively
In the order of a sequence you can assign any letter.
Step-by-step explanation: To find the next two terms in the pattern shown here, notice that we multiply by 2 to get from 4 to 8. Next we multiply 8 by 2 to get 16 and then we multiply by 2 to get from 16 to 32.
Continuing with the same pattern, we would next multiply 32 by 2 and would end with a product of 64. Finally we would multiply 64 by 2 and we would end up with a product of 128.
With this pattern, we can say that we will multiply 2 by each number that is in our pattern in order to get our next number in the pattern.
