Answer: OPTION B

Step-by-step explanation:

Multiply both denominators to find the Least Common Denominator:

$LCD=(3y-4)(y^2)$

Now, divide each original denominator by the LCD and multiply the result by each numerator. Then:

$=\frac{(6y^2+2y)(y^2)-(9y-7)(3y-4)}{(3y-4)(y^2)}$

Applying Distributive property, you get:

$=\frac{6y^4+2y^3-(27y^2-36y-21y+28)}{3y^3-4y^2}\\\\=\frac{6y^4+2y^3-27y^2+36y+21y-28}{3y^3-4y^2}$

Add the like terms in the numerator:

$=\frac{6y^4+2y^3-27y^2+57y-28}{3y^3-4y^2}$

Tonisha has a lemonade stand. She has $31 in expenses and wants to make $69 per day. If X represents the amount of revenue from

aksik [14]

Answer:

x - 31 $\geq$ 69

Tonisha has to make at least $100 in revenue

Step-by-step explanation:

Set up the inequality:

x - 31 represents her profit

Since she wants to make at least $69 a day, use $\geq$ 69

So, the inequality is x - 31 $\geq$ 69

Then, solve for x to find how much she has to sell:

x - 31 $\geq$ 69

x $\geq$ 100

So, Tonisha has to make at least $100 in revenue

80/17 = 4.7.

Since the number of clothing must be whole number, the number of clothing that she can buy would be 4

You draw one card at random from a standard deck of 52 playing cards. Find the probability that (a) the card is an even-numbered

DerKrebs [107]

Answer:

$P(even )=\frac{20}{52} =\frac{5}{13}$

$P(heart or diamond)=\frac{13}{52} +\frac{13}{52} =\frac{1}{2}$

$P(nine or face card)=\frac{4}{52} +\frac{12}{52} =\frac{4}{13}$

Step-by-step explanation:

You draw one card at random from a standard deck of 52 playing cards

Total cards = 52

5 even numbers in each suit. 4 times 5 = 20 even number cards

$P(even )=\frac{20}{52} =\frac{5}{13}$

(b) the card is a heart or a diamond

there are 13 heart and 13 diamonds

$P(heart or diamond)=\frac{13}{52} +\frac{13}{52} =\frac{1}{2}$

There are 4 nine and 12 face cards

$P(nine or face card)=\frac{4}{52} +\frac{12}{52} =\frac{4}{13}$
