4x - 1 = side of square 2x + 1 = length of rectanglex + 2 = width of rectangleSince their perimeters are equal, 4(4x - 1) = 2(2x + 1) + 2(x + 2) 16x - 4 = 4x + 2 + 2x + 410x = 10x = 1If we plug 1 in for x,Each side of the square is 4(1) - 1 = 3The perimeter is thus 12 The length of the rectangle = 2(1) + 1 = 3The width of the rectangle is 1 + 2 = 3The perimeter is this 2(3) + 2(3) = 12 So x = 1 is the verified.
hope this helps! (:
Answer:
126
Step-by-step explanation:
The probability is 90/500 = 18%
So, from 700 customers,
700 * 18% = 700 * 18/100 = 126
Therefore, 126 customers will be selected on saturday.
For this problem, let's assign a variable for the total amount of proteins needed daily/ Let that parameter be x. Now, the 48 grams is part of the total. The other portion is the one expressed in percentage. That accounts for 4% of x. Therefore, the equation would be:
x = 48 + 0.04x
Solving for x
x = 50
Thus, you will need 50 grams of protein daily.
