Answer:
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
Step-by-step explanation:
Solution:
The cost of book from publisher = 40%
Sales tax = 7.5%
Price of books to the student = p(x) = 1.075x + 0.40x
Where, x is cost of book.
P (60) =?
We know that,
P(x) = 1.075 + 0.40
= 1.475%
=148
Given, Cost of book, x = 60
P (60) = 148 – 60
= 88
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.

Answer:
x=33
Step-by-step explanation:
The angles would need to add to 180 to be supplementary
4x+ x+15 = 180
Combine like terms
5x+15 = 180
Subtract 15 from each side
5x+15-15 =180-15
5x = 165
Divide by 5
5x/5 =165/5
x=33

What is true about the sign of the difference when a positive integer is subtracted from a negative integar
Answer:
negative
Step-by-step explanation:
Suppose we have positive integer x and negative integer -y.
Subtracting x from -y gives:
-y - x
Clearly, if -y is negative and we're subtracting even more (x) from it, the answer will still be negative.
So, the sign is negative.

2x - 5y = 5 and y = x + 2
Answer:7
Step-by-step explanation:
Answer:
x = -5 & y = -3
Step-by-step explanation:
2x - 5y = 5 --------------------------(I)
y = x + 2 -----------------------(II)
Using substitution method
Substitute y = x + 2 in equation (I)
2x - 5(x + 2) = 5
2x - 5*x + (-5)*2 = 5
2x - 5x - 10 = 5
Combine like terms
-3x - 10 = 5 {Add 10 to both sides}
-3x = 5 +10
-3x = 15 {Divide both sides by (-3)}
x = 15/(-3)
x = -5
Substitute the x = (-5) in equation (II)
y = -5 + 2
y = -3
Anthony has a part-time job. He decides to save $10 for every $50 that he spends. Final question: If Anthony saved $60, how much money did he earn?
Answer:
300$
Step-by-step explanation:
If he save 10 for every 50, you just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300

Answer:
The answer is 14 hours
Step-by-step explanation:
The question states that h means hours and w is the total amount of money received.

Please solve this question.
Ram started his journey at 6:00 AM with an average speed at 20km/hr.
Hari started his journey two hours later (at 8:00 AM) with an average speed of 30km/hr.
We have to find time at which they meet each other[tex].[/tex]
★ Let they meet each other after t hours wrt 6:00 AM.
At that time, distance covered by ram must be equal to the distance covered by hari.
We know that,
distance = speed × time➤ Distance covered by Ram :
⭆ d₁ = v₁ × t
⭆ d₁ = 20 × t
➤ Distance covered by Hari :
Since hari started his journey after 2 hours so will take time = (t - 2) hours
⭆ d₂ = v₂ × (t - 2)
⭆ d₂ = 30 × (t - 2)
⭆ d₂ = 30t - 60
Now,
➠ d₁ = d₂
➠ 20t = 30t - 60
➠ 30t - 20t = 60
➠ 10t = 60
➠ t = 6 hrs
∴ They will meet at (6 + t) = 12PM
Hope It Helps!Answer: 12:00 pm (Noon)
Step-by-step explanation:
Let t represent the time (in hours) from 6:00 am
Use distance (d) = rate (r) × time (t)
Ram: time = t, r = 20 → d = 20t
Hari: time = t - 2, r = 30 → d = 30(t - 2)
Use Substitution method to solve the system of equations:
20t = 30(t - 2)
20t = 30t - 60
-10t = -60
t = 6
They travel the same distance when Ram rides his bike for 6 hours
and Hari rides his bike for 4 hours.
Ram: 6:00 am + 6 hours = 12:00 pm (Noon)
Hari: 8:00 am + 4 hours = 12:00 pm (Noon) [tex]\checkmark[/tex]

graph the line with the equation y = -5/2x + 2
Answer:
Step-by-step explanation:
Answer:
If you want to get the result like I did, Desmos is a great website that help you graph any kind of equation.
Step-by-step explanation:
I placed y=-5/2x +2 into desmos and it spat out this graph. If you want to do it algabreacly, I suggest making an x and y t-chart and start plugging in x numbers in terms of y. Lets say you plug in 1 as x, you would to 5/2(1) +2 giving you 2 5/2 or 4 1/2 as your y coordinate if x is 1. This makes your point (1, 4 1/2). I'd say do about 3 coordinates at least and then draw a line straight through those point giving you your graphed equation.
