if x Multiplied by 7 = 21, what is x
Step-by-step explanation:
Given that x is multiplied by 7 = 21 Then
7 * x = 21
or x = 21/ 7
Therefore x = 3.
Answer:
Solution,

Kiran paid $54.00 for 3 tickets to go to a corn maze. At the same rate, what is the cost of 5 tickets to the maze? *
Answer:90
Step-by-step explanation:
Answer: $90
Step-by-step explanation:
You can set up a proportion.
$54 = 3 tickets
x = 5 tickets
To find x, multiply 54 and 5.
54 × 5 = 270
Then divide 270 by 3.
270 ÷ 3 = $90
Since we figured out x = $90, this means that it costs $90 for 5 tickets.
hope this helps!!
What is the answer? 2c-5 C=4
Answer:
2(4)-5=3
we know that C is going to be multiplied by 2 and the value of C=4
so 2*4 = 2(4)
2(4)-5
2*4=8
8-5=3
So, the answer is 3

explain how it is possible that all proportional relationships are linear functions but not all linear functions are proportional relationships.
Proportional and linear functions are almost identical in form. The only difference is the addition of the “b” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).

What is the slope of a line that is perpendicular to the

Answer:
The slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.
Step-by-step explanation:
From the line equation, let us take two points
(0, 2)(4, 1)Finding the slope between two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:2\right),\:\left(x_2,\:y_2\right)=\left(4,\:1\right)[/tex]
[tex]m=\frac{1-2}{4-0}[/tex]
[tex]m=-\frac{1}{4}[/tex]
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be:
[tex]-\frac{1}{-\frac{1}{4}}=4[/tex]
Thus, the slope of a line that is perpendicular to the line
shown in the graph is = 4
Hence, option 'd' is true.

A certain relationship is defined as having only one corresponding y-value for each x-value. Which of the following best describes this relationship?
A.
variable
B.
expression
C.
function
D.
equation
Answer:
We conclude that a function is defined as having only one corresponding y-value for each x-value.
Hence, option (C) is true.
Step-by-step explanation:
We know that A function is a certain relationship is defined as having only one corresponding y-value for each x-value.
Considering the function
f(x) = x+1Here,
x is the input and f(x) or y is the output. 'x' is often called an independent value and y is called the 'dependent' value.Considering the table
x y
1 2
2 3
3 4
4 5
The values in the table satisfy the function y = x+1.
It is clear from the table that the function has only one corresponding y-value for each x-value. In other words, there is no repetition of 'x' value.
Therefore, we conclude that a function is defined as having only one corresponding y-value for each x-value.
Hence, option (C) is true.
David is buying 3 books in a trilogy set for $24.81. He will save $6.69 by buying the trilogy set instead of buying individual books. If each book costs the same amount, how much does each of the 3 books cost when purchased individually?
Answer:
Cost of each individual book = $10.5
Step-by-step explanation:
Given:
Cost of 3 book set = $24.81
Amount save = $6.69
Find:
Cost of each individual book
Computation:
Assume:
Cost of each individual book = a
Total cost = 3a
So,
Total cost = $24.81 + $6.69
Total cost = $31.5
So,
3a = $31.5
a = $10.5
Cost of each individual book = $10.5
Angle J and angle K are complementary angles. The measure of angle J is 18 less than the measure of angle K. Fine the measure of both angles.
Please and thank you.
Answer:
Step-by-step explanation:
If J and K are complementary, then J + K = 90. If J is 18 less than K, then:
J = K - 18. Now we have a system. We'll sub in K - 18 for J to the first equation:
K - 18 + K = 90 and
2K - 18 = 90 and
2K = 108 so
K = 54
Now that we know K, we'll sub in to find J:
J + 54 = 90 so
J = 36

Answer:
#1: A
#2: 2
I apologize if its wrong
Answer: A, 5
Explanation:
Simply create an slope-intercept equation using the given information. The initial fee is $5, which is the y-intercept and $2.75 every stop, which is our slope. The equation is y = 2.75x+5. Since this is an inequality and she's looking for the most amount of stops she can take before maximizing her budget, it needs to be a less than or equal to sign. Change the equation to be 5+2.75S≤21. Subtract 5 from both sides to get 2.75S≤16. Divide 2.75 to both sides to get S≤5.82. This would be estimated to around 5 stops, which would be the largest amount of stops.

A medium pizza at Benny's Pizza costs $13.60 plus $2.50 for each topping. At Ricco's
Pizza, a medium pizza costs $14.60 plus $2 for each topping. For how many toppings
will the pizzas cost the same price?
O 2 toppings
O They will always cost the same.
О 1 topping
O They will never cost the same.
Answer:
They will never cost the same.
Step-by-step explanation:
Answer:
2.5x +13.6 = 2x +14.6 (set them equal to each other and subtract 2x from both sides)
0.5x +13.6 = 14.6 (subtract 13.6 from both sides)
0.5x = 1 (divide both sides by 0.5)
x= 2
at two toppings they will cost the same
