Answer:

1 2/3

Step-by-step explanation:

8/9 + 7/9

Since the denominators are the same, we can add terms

15/9

This is an improper fraction so we can simplify

9/9 + 6/9

1 + 2/3

1 2/3

Answer:

4.) Choice B

5.) Choice A

Step-by-step explanation:

Question 4:

First you have to solve for y to get slope intercept form.

$2x-5y=6\\5y=-2x+6\\y=-\frac{2}{5}x+\frac{6}{5}$

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.

Question 5:

For this one I we will use this formula $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

I will choose the easy pairs to plug it in $(-12,-2) (20,6)$

$\frac{6--2}{20--12}\\\\\\\frac{8}{32}=\frac{1}{4}$

The slope is a fraction again but you can convert it and that'll be Choice A.

wo neighboring homeowners, , 2, simultaneously choose how many hours to spend maintaining a beautiful lawn. The average benefit

Fantom [35]

To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.

<h3>What is the average?</h3>

Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:

69 seconds.
58 seconds.
45 seconds.
120 seconds.
76 seconds.

The average time of my group of friends would be:

69 + 58 + 45 + 120 + 76 = 368

358 ÷ 73.6 seconds

The average of my group of friends would be 73.6 seconds.

According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.

Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

Part of arianna’s earnings are based on a 5% commission rate. At the end of the day arianna earned 14.98 in commission. How much

Katarina [22]

Arianna sold for $ 299.6

Solution:

Given that, Part of Arianna’s earnings are based on a 5% commission rate

At the end of the day arianna earned 14.98 in commission

Therefore,

Commission earned = $ 14.98

Commission rate = 5 %

Let "x" be the amount that Arianna sell that day

Therefore, according to question,

5 % of amount earned = 14.98

5 % of "x" = 14.98

Solve the above equation for "x"

$5 \% \times x = 14.98\\\\\frac{5}{100} \times x = 14.98\\\\5x = 14.98 \times 100\\\\5x = 1498\\\\Divide\ both\ sides\ of\ equation\ by\ 5\\\\x = 299.6$

Thus arianna sold for $ 299.6

Given the equation (x-a)^2(x-2)=x^3+bx^2+12x-72 find a and b

ivann1987 [24]

Isolate the variable by dividing each side by factors that don't contain the variable.

a=- \frac{ x^{2}- \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2} ,- \frac{ x^{2}+ \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2}

Solve for b by simplifying both sides of the equation then isolating the variable.

b= \frac{12}{x}+ \frac{72}{ x^{2} }-2+2a- \frac{4a}{x}+ \frac{ a^{2} }{x}- \frac{2a^{z} }{ x^{2} }

Hopefully i helped ^.^ Mark brainly if possible. Lol once again i saw the same question so why not answer it again!
