Brianna's thinking is incorrect.
Expessions A, and C. are equivalent.
For C, you add 5x and x together (because they have the same variable) to get 6x - 4.
For A, you subtract 9x and 3x (because they have the same variable) to get 6x- 4.
If the two lengths are 7 and 3, then I believe the length of the hypotenuse would be approximately 7.62.
Answer:
i think the perimeter is 31 m
Step-by-step explanation:
A^2 + B^2 = C^2
(10)^2 + (26)^2 = C^2
100 + 676 = 776
Square root of 776cm = 28.86cm rounded
Answer:
x = 60 cents.
Step-by-step explanation:
The man wants to make up 100 one-pound jars of nuts, it means he will need 100 pounds of nuts. He plans to use 40 pounds of one type of nuts, so he needs 60 pounds of the other type of nuts to get 100 pounds.
Now, with this we can write a linear equation:
(40*0.75)+(60*x) = 100*0.66 (1)
Where:
- 0.75 is the unit price of the 40 pounds of one type of nuts.
- x is the unit price of the 60 pounds of the other type of nuts.
- 0.66 is the unit price of 100 one-pound jars.
Let's solve the equation (1) for x:

Therefore, x = 60 cents.
I hope it helps you!
