Answer:
3,6
Step-by-step explanation:
Plug 2x(y) into 5x -y = 9
5x -2x = 9
Add like terms.
3x = 9
Divide both sides by 3.
x = 3
Now, in order to find y, plug 3(x) into y = 2x
y = 2(3)
y = 6
The solution of system of equation is x=3 and y=6.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y=2x .....................(1)
5x-y=9...............(2)
Now substitute the value of y in equation (2), we get
5x - 2x = 9
3x = 9
Divide both side by 3.
x= 3
and, y= 2x = 6

The scale of a map says that 3 cm represents 8 km.
What distance on the map (in centimeters) represents an actual distance of 20 kilometers?
What is the actual number of kilometers that is represented by 12 centimeters on the map?
PLEASE HELP ME ASAP I WILL MAKE YOU BRAINIEST!!
Answer:
Step-by-step explanation:
Problem 1
Set Up the Proportion
3 cm / 8 km = x / 20 km Cross multiply
3*20 = 8x Combine the left
60 = 8x Divide by 8
60/8 = x
7 4/8 = x
7 1/2 km = x
7.5 km = x
Problem 2
3 cm / 8km = 12 cm / x Cross multiply
3x = 12 * 8 Combine the right
3x = 96 Divide by 3
3x/3 = 96/3
x = 32 km

recipe for two dozen cookies calls for 234cups of sugar. How much sugar is needed to make one dozen cookies? A 38cupsover33, cups B 138cupsove1r, cups C 134cupsover34, cups D 512cups5 and 1 half cup
Answer:
117 cups
Step-by-step explanation:
two dozen cookies calls for 234cups of sugar
2 dozen cookies = 234 cups of sugar
How much sugar is needed to make one dozen cookies?
Let x = cups of sugar needed
1 dozen cookies = x cups of sugar
2 dozen cookies : 234 cups of sugar = 1 dozen cookies : x cups of sugar
2 : 234 = 1 : x
2 / 234 = 1 / x
Cross product
2*x = 234 * 1
2x = 234
x = 234 / 2
= 117 cups

The formula is 2πr. 2 * 3.14 * 7 6.28 *7 = 43.96An amusement park charges a $12 parking fee plus 25 per person. What is the total cost for 32 people?
Answer:
The total amount for 32 people is 15.36
Step-by-step explanation:
we know that for 25 people is $12 so we need to find how much it would be for one person. you would need to divide $12 / 25. from this you would get 0.48, so for one person it's 48 cents. next you're going to subtract 25 from 32, this leaves you with seven people who aren't in a group of 25. you then multiply 7 × this equals to 3.36, add 3.36 to $12 and you'll get your total 15.36.

A square and a rectangle have the same area. The length of the rectangle is twelve more than twice times the side of the square. The width of the rectangle is eight less than the side of the square. Let x be the length of the side of the square. Using the information above, what is the value of x?
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
Given
Shapes: Square and Rectangle
Square:
[tex]Length = x[/tex]
Rectangle:
[tex]Length = 12 + 2x[/tex]
[tex]Width = x- 8[/tex]
Required
Find x
First, we calculate the area of the square.
[tex]Area = x * x[/tex]
[tex]Area = x^2[/tex]
Next, we calculate the area of the rectangle
[tex]Area = (12 + 2x) * (x - 8)[/tex]
[tex]Area = 12x -96 + 2x^2 - 16x[/tex]
[tex]Area = 2x^2 - 16x + 12x -96[/tex]
[tex]Area = 2x^2 -4x -96[/tex]
Since both areas are equal, we have:
[tex]x^2 = 2x^2 -4x -96[/tex]
Equate to 0
[tex]2x^2 -x^2 -4x -96= 0[/tex]
[tex]x^2 -4x -96= 0[/tex]
Expand:
[tex]x^2 - 12x + 8x -96 = 0[/tex]
[tex]x(x - 12) + 8(x - 12) = 0[/tex]
[tex](x + 8)(x - 12) = 0[/tex]
[tex]x + 8 = 0[/tex] or [tex]x - 12 = 0[/tex]
[tex]x = -8[/tex] or [tex]x = 12[/tex]
But x can't be negative.
Hence:
[tex]x = 12[/tex]

Graph a line that contains the point (3,-6) and has a slope of
2
khan academy i need it!!
Answer:
[tex]\boxed {\boxed {\sf y= 2x-12}}[/tex]
Step-by-step explanation:
We are given a slope and a point, so we can use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point.
The slope is 2 and the point is (3,-6).
[tex]m= 2\\x_1=3 \\y_1=-6[/tex]
Substitute the values into the formula.
[tex]y--6=2(x-3)[/tex]
[tex]y+6=2(x-3)[/tex]
Distribute the 2 on the right side of the equation.
[tex]y+6=(2*x)+(2*-3)[/tex]
[tex]y+6=2x-6[/tex]
We want to get the line into the form: y=mx+b. We have to isolate y on one side of the equation. 6 is being added to y. The inverse of addition is subtraction; subtract 6 from both sides of the equation.
[tex]y+6-6=2x-6-6[/tex]
[tex]y=2x-6-6[/tex]
[tex]y=2x-12[/tex]
The line is y=2x-12 (slope=2 and y-intercept=-12)

Answer:
The answer on the right bottom
Step-by-step explanation:
3/4 × 1/2 = 3/8
None of them have 3 shaded but the right bottom
Therefore that'd be your answer
Answer:
bottom right
Step-by-step explanation:
In order to know the answer, you have to find the product of [tex]\frac{3}{4}[/tex] x [tex]\frac{1}{2}[/tex].
Multiply both numerators and denominators in order to get the answer.
[tex]\frac{3}{4}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{8}[/tex] (this is the lowest term already)
If you check among the choices, it is only the bottom right choice that shows correct shading of the fraction. The diagram divides the right side into 4 equal parts. If you divide the left side into 4 equal parts like this, you'll surely get 8 equal parts of the total diagram. This represents the denominator, 8. The shaded portion represents the numerator, 3.
