We need to think, 28 / 42 = x / 54.
We need to do a proportion for this problem!
First, line up both fractions, then put a equal sign between both fractions.
28 / 42 = x / 54.
We multiply in a diagonal and then we divide by the one without a diagonal.
28 and 54 are a diagonal.
We multiply both numbers!
54 x 28 = 1,512.
Then, we divide by 42.
1,512 / 42 = 36.
Therefore, x = 36.

To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.
1. 29.68 / 4 = 7.42
So $7.42 is the unit price.
2. 625 / 6 = 104 (rounded to the nearest whole number)
So Jess can type 104 words per minute.
Answer:
x = -0.8 and 10.8
Step-by-step explanation:
Given the equation x2 – 10x – 8= 0
Using the general formula
x = -b±√b²-4ac/2a
x = -(-10)±√(-10)²-4(1)(-8)/2(1)
x = 10±√100+32/2
x =10±√132/2
x = 10±11.489/2
x = 10-11.489/2 and 10+11.489/2
x = -1.489/2 and 21.489/2
x = -0.8 and 10.8
