Step-by-step explanation:
let the unknown number be x
90/100 × x =6.1
× = 6.1 × 100/ 90
x = 610/ 90
x = 6.778
Answer:
D
Step-by-step explanation:
Since 1 and c are supposed to be equal, I put 2.35+0.25x=1.75+0.4x and solved that for the x. I got 4. Then, since I want to find the price of the beef, I plugged the 4 in the equation of "b" and got 3.35.
I made many mistakes when solving so I restarted many times which is why it took so long to answer. Whew, I actually found the answer though!
If you want to help, mark me brainliest, I'm only 1 away from getting virtuoso! That would make my day, and hope I made yours.
Bye!
Answer:
L = 2r + 3
Step-by-step explanation:
Given parameters:
Area of rectangle = 14r + 21
Width of the rectangle = 7ft
Unknown:
Length of the rectangle = ?
Solution:
If the length of the rectangle is designated as L;
Area of a rectangle = Length x width
Now insert the parameters:
14r + 21 = L x 7
L = 
L = 2r + 3
Answer:
16/21
