Cole needs at least $815 to cover travel and hotel expenses for an upcoming national singing competition. He is setting up a wee

kly singing gig at a local coffee shop to pay for the costs. If the coffee shop agrees to pay him $125 each week after he made $65 at an open mic night at the shop, how many weeks could Cole perform to raise the amount he needs for the competition?

For this case we have:

Let x be the number of weeks you should work in the store. We have:

125x + 65 \geq 815

That is,125xrepresents the profit obtained according to the number of weeks worked.

65, represents the gain obtained in one night, in the store.

Cole's earnings must be greater than or equal to the cost of the trip and stay of the singing competition, so he can cover it.

Clearing x:

125x\geq 815-65\\ 125x\geq 750

x \geq\frac{750}{125}

x \geq6

Thus, the minimum number of weeks that Cole must work to cover the costs of the competition is 6.

Answer:

The minimum number of weeks is 6.

x \geq6

It would take 6 weeks for Cole to make 750$ and the 65$ he had received from the open mic would make it 815$

This is 70 points I will report anyone who answers wrong just for points! I will be asking TWO questions Please answer correctly

QUESTION 1: In these type of question, the easiest way to get the answer is try to plug in the x and y values from the options given in the equation given, So in the first question all the choice except C are more then 14 if you plug in x and y's, for eg, if you plug in x = 3 and y = 2 , you get (3+3)2 = 14 6 x 2 = 14 12 is not equal to 14, so this eliminates this choice but if you chose C you get, (11+3)1 = 14 14 = 14 so this makes C the solution for first question and for the second question do the same thing, and the answer will be D. Hope this helps




QUESTION 2: 5xy + 9 = 44

5xy = 35

xy = 7

solution pairs are:

C. (1, 7) and (7, 1)

not mentioned: (-1.-7) and (-7, -1)






Hope this helps

Wesleys mother is 57 years old. her age is three years more than twice edwins age. what is wesleys age?
natita [175]

Answer: Edwin is likely a typo for Wesley.

Step by step:

Wmom=57

Wmom=3+2e

57=3+2e

54=2e

27=e

Edwin is 27 years old.

Aside from a typo, one can speculate on Wesley's age. He's likely between 20 and 39 years old based on his mother's age. If you want to delve into societal norms, Wesley is likely to be a name from a white middle to upper class parentage, so it's less likely he was had when his mother was a teen, or even in her early twenties because college, so move that age zone to 20 to 34. Then consider that having children later than 35 is consideration for a "risky" pregnancy and most women are urged to aim for before 33, but most upper middle class white women will be pressured to baby before 30. So, adjust Wesley's age zone to 27 to 34. And then...idk. But in all honesty I think Edwin is meant to be Wesley, because it's a math problem not a sociology one.

Inscribed angles math lib <br> Need help with 9 and 10 thank you!!
telo118 [61]

Answer:

54° and 110°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°

(9)

19x - 26 + 7x - 2 = 180

26x - 28 = 180 ( add 28 to both sides )

26x = 208 ( divide both sides by 26 )

x = 8

Then

∠ EFG = 7x - 2 = 7(8) - 2 = 56 - 2 = 54°

(10)

21x - 33 + 14x + 3 = 180

35x - 30 = 180 ( add 30 to both sides )

35x = 210 ( divide both sides by 35 )

x = 6

Then

∠ YVW = 14x + 3 = 14(6) + 3 = 84 + 3 = 87°

The inscribed angle YVW is half the measure of its intercepted arc YW, so

arc YW = 2 × 87° = 174°, then

arc XW = 174° - 64° = 110°
