Answer:
64 - (-16/3) = 208/3
Step-by-step explanation:
I think the problem may be written incorrectly. For this to be correct, it must be 64- (-16/3) = 208/3.
To get 203/3 you have to find a common denominator because in order to subtract (or add) fractions, they must have the same denominator.
However, 64 does not have the same denominator as -16/3!!
We can write 64 as 64/1, and to give it the same denominator as -16/3, we need to multiply the denominator by 3
BUT we have to do the same thing to the numerator!!! We can't only change the denominator. If one changes, the other has to change too.
So lets multiply the numerator and denominator by 3. 64 x 3 = 192
1 x 3 = 3
Now we have 192/3
Subtracting a negative number is the same as adding. So instead we can write 192/3 + 16/3
Add 192 and 16 to get 208, so now you have 208/3
what is the answer or solution-15-3p=6
Answer:
P = - 7
Step-by-step explanation:
To solve we must put all the literals (letters) on one side of the operation and all the free numbers on the other. To do this we are going to do the same operations on both sides of the equal sign
- 15 - 3p = 6
So, we are going to add 15 on both sides
- 15 - 3p + 15 = 6 + 15
- 3p = 21
We are goint to divide everything by -3
-3p/-3 = 21/-3
It result:
p = -7We check as follows:
We are going to replace the unknown (p) by the value we gave it already (-7)
-15 - 3(-7) = 6
-3 × -7 = +21
-15 + 21 = 6
6 = 6
we have the correct result

Step-by-step explanation:
Using f(x) =x^2/3-2, determine if each statement below is true or false. Show the work that justifies your answer. The statements are A. F(6)=f(-6) B. F(6)=2 • f(3)
Answer:
[tex]f(6) = f(-6)[/tex] --- True
[tex]f(6)=2 * f(3)[/tex] --- False
Step-by-step explanation:
Given
[tex]f(x) = \frac{x^2}{3} - 2[/tex]
Solving (a): f(6) = f(-6)
First, we solve for f(6) by substituting 6 for x in [tex]f(x) = \frac{x^2}{3} - 2[/tex]
[tex]f(6) = \frac{6^2}{3} - 2[/tex]
[tex]f(6) = \frac{36}{3} - 2[/tex]
[tex]f(6) = 12 - 2[/tex]
[tex]f(6) = 10[/tex]
Next, we solve for f(-6) by substituting -6 for x in [tex]f(x) = \frac{x^2}{3} - 2[/tex]
[tex]f(-6) = \frac{-6^2}{3} - 2[/tex]
[tex]f(-6) = \frac{36}{3} - 2[/tex]
[tex]f(-6) = 12 - 2[/tex]
[tex]f(-6) = 10[/tex]
We have that:
[tex]f(6) = f(-6) = 10[/tex]
Hence, the statement is true
Solving (b): [tex]f(6)=2 * f(3)[/tex]
We have that:
[tex]f(6) = 10[/tex]
Next, we solve for f(3) by substituting 3 for x in [tex]f(x) = \frac{x^2}{3} - 2[/tex]
[tex]f(3) = \frac{3^2}{3} - 2[/tex]
[tex]f(3) = \frac{9}{3} - 2[/tex]
[tex]f(3) = 3 - 2[/tex]
[tex]f(3) = 1[/tex]
[tex]2 * f(3) = 2 * 1[/tex]
[tex]2 * f(3) = 2[/tex]
So:
[tex]f(6)=2 * f(3)[/tex]
[tex]10 \neq 2[/tex]
Hence, the statement is false

Step-by-step explanation:
Answer:
The X intercept is 2, the Y intercept is -4
Step-by-step explanation:
Look at the graph, the Y-intercept is the point where the red line intersects the Y-axis. The X intercept is where the red line intersects the X axis.
Y-axis is vertical (top to bottom)
X-axis is horizontal (side to side/left to right/right to left)

Can someone explain this and help
Answer:
x = 43
Step-by-step explanation:
since the line is parallel, there are a few relationships that goes on in between the parallel lines with the angles formed by the third line (the third line is known as a transversal)
the two angles shown are same side interior angles because they are on the same side of the transversal and on the inside of the parallel lines
same side interior angles always add up to 180 since, if you put them together, they would form a straight angle
so we can set the equation to x + 27 + x + 67 = 180
add like terms: 2x + 94 = 180
subtract 94 from 180: 2x = 86
divide both sides by 2: x = 43

The 17th term of an Arithmetic sequence is 51. If the commons difference is 7, what is the first term ?
Answer:
The first term is:
[tex]a_1=-61[/tex]Step-by-step explanation:
The arithmetic sequence is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
where
[tex]a_1[/tex] is the first term
[tex]d[/tex] is the common difference
as
the 17th term of an arithmetic sequence is 51.
i.e. [tex]a_{17}=51[/tex]
so
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_{17}=a_1+\left(17-1\right)d[/tex]
[tex]51=a_1+\left(17-1\right)7[/tex] ∵ [tex]n = 17[/tex], [tex]a_{17}=51[/tex] , [tex]d=7[/tex]
[tex]a_1+112=51[/tex] ∵ [tex]\left(17-1\right)\cdot \:\:7=112[/tex]
[tex]a_1=-61[/tex]
Therefore, the first term is:

The Key Club is having a fundraising dinner for charity. The venue that holds a maximum of 500 people will
cost $1000 and it costs $20 per person for the food. The two charity representatives get to attend for free.
Write an inequality and then determine how many people must come to keep costs at most $25 per person.
Answer:
[tex]\dfrac{\$1000+\$20x}{x} \leq \$25[/tex]
Minimum 200 people other than the 2 charity representatives.
Step-by-step explanation:
Given that:
The venue can hold a maximum of 500 people.
Cost of venue = $1000
Per person cost for food = $20
Two charity representatives get to attend the dinner for free.
To find:
The inequality and to determine how many people must come to keep costs at most $25.
Solution:
Let the number of people attending the dinner = [tex]x[/tex]
Cost of food for [tex]x[/tex] people = [tex]\$20x[/tex]
Total cost = $1000 + [tex]\$20x[/tex]
Cost per person = Total cost divided by Number of people attending the dinner.
As per question statement:
[tex]\dfrac{\$1000+\$20x}{x} \leq \$25\\\Rightarrow 1000+20x\leq25x\\\Rightarrow 1000 \leq 5x\\\Rightarrow x\geq 200[/tex]
Therefore, the answer is:
Minimum 200 people other than the 2 charity representatives should attend the dinner.
