A one-way bus ride costs $1.75. A 30-day bus pass costs $42. When is the 30-day pass a better deal?

motikmotik

Answer:

After 24 days.

Step-by-step explanation:

42 Dollars / 1.75 Dollars per day = 24 Days. This means that at 24 days, the one-way bus ride costs as much as a 30-day pass. After 24 days, the 30-day pass is cheaper.

Find the solution to the system. Write your solution as an ordered pair (x,y)

Studentka2010 [4]

Answer:

Infinitely many

Step-by-step explanation:

If we multiply the equation x-3y=7 by 3, we get 3x-9y=21, which is also the second equation. That means the two lines are on top of each other, meaning infinite many solutions.

Will crown the correct answers brainliest 3x

Solnce55 [7]

Answer :

(1) $\frac{1}{x}+\frac{1}{y}=\frac{y+x}{xy}$

(2) $\frac{1}{5x}+\frac{1}{3y}=\frac{3y+5x}{15xy}$

(3) $\frac{1}{7x}-\frac{1}{2y}=\frac{2y-7x}{14xy}$

(4) $\frac{2}{5x}+\frac{3}{7y}=\frac{6y+15x}{21xy}$

(5) $\frac{7}{11x}-\frac{1}{33y}=\frac{231y-11x}{363xy}$

(6) $\frac{1}{2x}+\frac{3}{x}-\frac{1}{7y}=\frac{7y+42y-2x}{14xy}$

Step-by-step explanation :

(1) The given expression is: $\frac{1}{x}+\frac{1}{y}$

$\frac{1}{x}+\frac{1}{y}=\frac{y+x}{xy}$

(2) The given expression is: $\frac{1}{5x}+\frac{1}{3y}$

$\frac{1}{5x}+\frac{1}{3y}=\frac{3y+5x}{(5x)\times (3y)}=\frac{3y+5x}{15xy}$

(3) The given expression is: $\frac{1}{7x}-\frac{1}{2y}$

$\frac{1}{7x}-\frac{1}{2y}=\frac{2y-7x}{(7x)\times (2y)}=\frac{2y-7x}{14xy}$

(4) The given expression is: $\frac{2}{5x}+\frac{3}{7y}$

$\frac{2}{5x}+\frac{3}{7y}=\frac{(2\times 3y)+(3\times 5x)}{(5x)\times (7y)}=\frac{6y+15x}{21xy}$

(5) The given expression is: $\frac{7}{11x}-\frac{1}{33y}$

$\frac{7}{11x}-\frac{1}{33y}=\frac{(7\times 33y)-(1\times 11x)}{(11x)\times (33y)}=\frac{231y-11x}{363xy}$

(6) The given expression is: $\frac{1}{2x}+\frac{3}{x}-\frac{1}{7y}$

$\frac{1}{2x}+\frac{3}{x}-\frac{1}{7y}=\frac{(x\times 7y)+(3\times 2x\times 7y)-(2x\times x)}{(2x)\times (x)\times (7y)}=\frac{7xy+42xy-2x^2}{14x^2y}=\frac{7y+42y-2x}{14xy}$

Please help asap, I'm so confused lol.

Sladkaya [172]

Answer: $450

Step-by-step explanation:

We can form an equation representing the problem. The question is essentially asking 60% of what is equal to $270. If we define that what as a variable 'x', we get the following:

$\frac{60}{100} *x=270$

$\frac{60x}{100} =270$

Multiply both sides by 100:

$\frac{60x}{100} *100=270*100$

$60x=27,000$

Divide both sides by 60 to solve for the value of 'x':

$x=\frac{27,000}{60} =450$

Answer is 450 bucks

We can check this answer by taking 60% of $450. In principal, this should return the discount of $270.

$\frac{60}{100} *450=270$

Yup, it checks out

Determine whether the ordered pair is a solution of the linear equation y = 11r - 4 (0 -4)

KiRa [710]

Hi there!

»»————-　★　————-««

I believe your answer is:

Yes, it is a solution.

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

I am assuming that 'r' is supposed to be 'x'.

⸻⸻⸻⸻

$y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}$

⸻⸻⸻⸻

The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.

⸻⸻⸻⸻

$y = mx+b$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
