Answer:

\frac{40}{19}\frac{cases}{hour} or 2\frac{2}{19}\frac{cases}{hour}

Step-by-step explanation:

we know that

Jerry hears 5 cases every 2\frac{3}{8} hours

so

To find how many cases does he hear per hour, divide 5 cases by 2\frac{3}{8} hours

convert mixed number to an improper fraction first

2\frac{3}{8}=\frac{2*8+3}{8}=\frac{19}{8}

\frac{5}{(19/8)} =\frac{40}{19}\frac{cases}{hour}

convert to mixed number

\frac{40}{19}\frac{cases}{hour}=\frac{38}{19}+\frac{2}{19}=2\frac{2}{19}\frac{cases}{hour}

$1.12 for 8.2 ounces? Unit Rate
Reil [10]
That is around 13 or 14 cents. The specific answer is 13.65853659 cents, but you can either round up to 14 or round down to 13 (rounding up to 14 is the correct way to do it.)

First you divide 1.12 by 8.2 to get the unit rate because It takes $1.12 to buy 8.2 ounces. 1.12/8.2=13.65853659

The width of a rectangle is the length minus 2 units. The area of the rectangle is 35 units. What is the width, in units, of the
Andrews [41]

Answer: width = 5 units

Step-by-step explanation:

Let L represent the length of the rectangle.

The width of a rectangle is the length minus 2 units. It means that the width of the rectangle is (L - 2) units.

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of the rectangle is 35 units. It means that

L(L - 2) = 35

L² - 2L = 35

L² - 2L - 35 = 0

L² + 5L - 7L - 35 = 0

L(L + 5) - 7(L + 5) = 0

L - 7 = 0 or L + 5 = 0

L = 7 or L = - 5

Since the length cannot be negative, then

L = 7 units

Width = 7 - 2 = 5 units

Which are solutions of x2 + 5x = 2? Check all that<br> apply.
strojnjashka [21]

Answer:

x=-5/2+-√33/2

Step-by-step explanation:

x^2+5x=2

you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square.

Your answer is then

x=-5/2+-√33/2
