Step-by-step explanation:
A group of 8 friends went to lunh and Spent a total of $76 which included the food bill in the tip of $16 they decide to split the bill into evenly among themselves
Answer:
The equation 1/8(x+16)=76/8 represents the situation, where x is the food bill.
The solution x=60 represents the total food bill.
Step-by-step explanation:
As in the question it is mentioned that there is eight group of friends and the total amount incurred is $76 that also involved $16
Now let us assume the food bill be x
So the equation would be
(x + 16) ÷ 8 = 76 ÷ 8
(x + 16) ÷ 8 = 9.5
x + 16 = 9.5 × 8
x = 76 -16
x = 60
So, the bill of food is 60

You and your mom enter a drawing with 3 different prizes. The prizes are
awarded at random.
If a total of 10 people entered the drawing, in how many ways can you win
first prize and your mom win second prize?
a. 8
b. 2
c. 10
d. 1
Answer:
The correct answer is 8.
Step-by-step explanation:
There are 2 ways that you can win first prize and your mom can win the second prize.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 10 people who entered the drawing.
Since the prizes are awarded at random, the probability of you winning the first prize is 1/3, and the probability of your mom winning the second prize is 1/2.
We can use the multiplication principle of counting to find the number of ways that you can win first prize and your mom can win the second prize.
The number of ways that you can win first prize is 1 since there is only one first prize and you are one of the 10 people who entered.
Once the first prize winner is chosen, there are 9 people left, and the number of ways that your mom can win the second prize is 1 out of 9.
The total number of ways that you can win first prize and your mom can win the second prize is:
1 × 1/3 × 1/2 × 9 = 3/2
However, the answer cannot be a fraction or decimal, since we are counting the number of ways in which events can occur.
Therefore, we round up to the nearest integer and get:
3/2 ≈ 2
Therefore,
There are 2 ways that you can win first prize and your mom can win the second prize.

A. 70 degrees
B. 79 degrees
C. 55 degrees
D. 44 degrees
Answer:
D because that is the smallest angle on there baby doll
Step-by-step explanation:
have a nice day sugar bear
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4x + 8x - 9 + 57 = 180, that is
12x + 48 = 180 ( subtract 48 from both sides )
12x = 132 ( divide both sides by 12 )
x = 11
Thus
∠ A = 4x = 4 × 11 = 44° → D

Perform the indicated multiplication: 2 - 3x - 12 = 9 - 3x
Gather all the x terms on one side and all the constants on the other:

An airplane travels at a constant speed of 320 miles per hour. How far, in miles, will the airplane travel in 15 minutes?
Answer:
80 miles.
Step-by-step explanation:
If it is traveling at 320 miles per hour, and its asking how much its traveled in 15 minutes you do this:
Since 15 minutes is 1/4 of an hour, you take 1/4 of how fast they are traveling at mph, which in this case is 320 mph.
320/4=80
The airplane will travel 80 miles in 15 minutes.
What is Distance?The length along a line or line segment between two points on the line or line segment.
we need to use the formula of distance.
distance = speed × time
Since the speed of the airplane is 320 miles per hour, we need to convert 15 minutes to hours:
15 minutes = 15/60 = 0.25 hours
Now we can substitute the values into the formula:
distance = speed × time
distance = 320 × 0.25
distance = 80
Therefore, the airplane will travel 80 miles in 15 minutes.

The value of (3 + x) / (x + 3) = 1
The numerator of the expression (3 - x) / (x - 3) can be written as,
⇒ - 1 (x - 3)
The value of (3 - x) / (x - 3) = - 1
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression are,
⇒ (3 + x) / (x + 3) and (3 - x) / (x - 3)
Now, We can solve as;
The value of (3 + x) / (x + 3) is,
⇒ (3 + x) / (x + 3) = (x + 3) / (x + 3)
= 1
And, The numerator of the expression (3 - x) / (x - 3) can be written as,
⇒ (3 - x) = - 1 (x - 3)
And, The value of (3 - x) / (x - 3) is,
⇒ (3 - x) / (x - 3) = - (x - 3) / (x - 3)
