you went out to eat with 3 friends and your meal cost 72.50 how much was the bill if 6.75 sale taxes was included

Answers

Answer:

$29.67 each

Step-by-step explanation:

6.75% of $72.50 = $4.90

72.50 + 4.90 = $77.40

15% of 77.40 = 11.61

77.40 + 11.61 = 89.01

89.01 divided by 3 = $29.67 each

Wait I’m confused what exactly are we suppose to do like what do u mean
Find the slope.
m=(y2-y1)/(x2-x1)
Plug in the y-coordinates of each of the ordered pairs. That is 4 and -2
Plug in the x-coordinates of each of the ordered pairs. That is -4 and 5
m=(4-(-2))/(-4-5)
m=6/-9
m=-2/3
Now that you know the slope, you want to take one of the ordered pair and plug them into the equation y=mx+b. I’ll take (-4,4). You want to find the b.
4=-2/3(-4)+b
4=8/3+b
4/3=b
So, the slope is -1/3 and the y-intercept is 4/3.
Equation: y=-2/3x+4/3

The costume jewelry and accessories for the show are bought from sales racks at two different stores on different days. Use x to represent the price of each item on the sales rack at the first store and y to represent the price of each item on the sales rack at the second store.

On the first day, the students spent $30 on 4 items from the first store and 7 items from the second store. On the second day, the students spent $22 on 3 items from the first store and 5 items from the second store. On the third day, the students need to buy 10 items from the first store and 17 items from the second store.

What is the amount of money the students will need on the third day? Find your answer by creating and solving a system of linear equations based on the first day and the second day. Explain your reasoning.

Answers

Answer:

74

Step-by-step explanation:

Using linear equations, we are given two equations from the questions:

4x +7y=30 from day one and 3x +5y=22 from day two

Multiply the first equation by 3 and second by 4 giving us

12x +21y=90 and 12x +20y=88. Minus both equations.

12x - 12x +21y - 20y= 90 - 88, Gives you y=2,

You can now use the value of y to find x.

4x + 7y = 30

4x + 7(2)= 30

4x + 14= 30. Minus 14 on both sides giving you

4x=16. Divide both sides by 4.

x=4

Now use both values to find how much money is needed on the third day.

10x + 17y

=10(4) + 17(2)

=40 +34

Find f(-2).

Answers

Answer:

-4

Step-by-step explanation:

The value of the function evaluated at [tex]x = -2[/tex] is -4.

The horizontal axis represents the set of the domain of the function, whereas the vertical axis is for the set of the range of the function. In this exercise, we need to need to find the value on the vertical axis that corresponds with a given value of the horizontal axis ([tex]x = -2[/tex]).

By direct inspection, we conclude that [tex]f(-2) = -4[/tex].

I will give brainliest, Will give Brainliest.....Does this sound good :)ome kids think that drugs are healthy. Vaping is good for you because it doesnt do anything. Weed is good for you because it helps you calm down and forget. These are perfect examples as to why they are not good. Vaping damages your lungs and can give your body cancer. Over time, smoking weed may cause chronic cough and other health issues. Both vaping, weed, cigarettes, alcohol, and many more drugs are not good for you or your body.Drugs are used across the world. Whether they are used properly or abused. Drugs are easy to become addicted to. They can cause substance abuse, which leads to jail time. While drugs also heal people, for example, prescription drugs when used properly are beneficial. They need to be used in restraint because even medically given to you, they are addictive. For example, pain-reducing opioids, though they are helpful they are addictive. All minds are affected; it's not just a teenager thing. Drugs should be monitored by someone, and while it is slightly out-of-pocket, it's a lot better than spending possible years in prison.Vaping may be a little better than weed or cigarettes but it still harms your body in multiple ways. It causes you to crave and if you dont follow that craving it will lead to withdrawal symptoms. Nicotine is an addictive chemical. It is a toxic substance. It raises your blood pressure and spikes your adrenaline, which then increases your heart rate. Increased heart rate can conclude to having a heart attack.An abundance of alcohol can harm the liver. This can lead to hepatitis, which is the buildup of scar tissue that eventually destroys the organ. Alcohol may cause kidney, bladder, and prostate inflammation. Alcohol is also an addictive substance, though alcohol may relieve pain and make you forget things, too much will make you drunk and incoherent.Opioids are a class of drugs used to reduce pain. Prescription opioids can be prescribed by doctors to treat moderate to severe pain, but can also have serious risks and side effects. Common types are oxycodone (OxyContin), hydrocodone (Vicodin), morphine, and methadone. Fentanyl is a synthetic opioid pain reliever.
