Jordan is painting his kitchen. To get the color he wants, he mixes 2 parts red paint and 6 parts yellow paint.
If he needs 18 parts of yellow paint, how much red paint will he need?
The solution is 6 parts of red paints
The number of red paints for the color to paint the kitchen is given by the equation A = 6 parts of red paints
What is an 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.
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 data ,
Let the number of parts of red paint be represented as A
Now , the equation will be
The number of red paint parts for 6 parts of yellow = 2 parts of red paint
The number of parts of yellow paint = 3 x 6 parts
The number of parts of yellow paint = 18 parts of yellow paint
So ,
The number of parts of red paint for 18 parts of yellow paint A = 3 x number of red paint parts for 6 parts of yellow
Substituting the values in the equation , we get
The number of parts of red paint for 18 parts of yellow paint A = 3 x 2
The number of parts of red paint for 18 parts of yellow paint A = 6 parts
Therefore , the value of A is 6 parts
Hence , the number of parts of red paint is 6 parts

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as w. The angle adjacent to w is marked as z, and the other two angles inside the triangle are marked as x and y.
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
In which step did the student first make a mistake and how can it be corrected? (5 points)
Select one:
a. Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of corresponding angles)
b. Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)
c. Step 1; it should be m∠x + m∠y + m∠z = 90 degrees (corresponding angles)
d. Step 2; it should be m∠w + m∠z = 90 degrees (alternate exterior angle)

For which pair of points can you use this number line to find the distance?
A number line going from negative 2 to positive 8. Points are at 1 and 7.
A-(–4, 1) and (7, –4)
B-(–4, 1) and (–4, 7)
C-(–1, –4) and (–4, 7)
D-(–4, –1) and (–4, –7)
Answer:
b or c wait it is B i am pretty sure
We can use the number line for the pair of points (-4,1) and (-4,7) to find the distance.
What is a number line?Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines.
Given that a number line going from negative 2 to positive 8. Points are at 1 and 7.
Remember that the distance between two points (a,b) and (a,c) can be found by calculating the distance between b and c, the second coordinates.
Also, for a pair of points (x,y) and (z,y), we can determine the distance between those two points by calculating the distance between x and z.
Therefore, we need to find pair of point whose form are; (a,b) and (a,c) or (a,b) and (c,b).
In this case of (-4,1) and (-4, 7), and (-4,-1) and (-4,-7).
For the first pair of points, we have the distance between 1 and 7, and, as for the second pair of points, the distance between -1 and -7.
Thus, the answer is (-4,1) and (-4,7).

Each batch of cookie mix needs 0.4 cups of sugar, and each batch can make 16 cookies. If Ashley is making 4 batches of cookies, how much sugar does she need?
Answer:
you will need 1.6 cups of sugar
Step-by-step explanation:
The solution is 1.6 cups
The number of cups of sugar needed for 4 batches of cookies is 1.6 cups
What is an 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.
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 data ,
Let the equation be represented as A
Now , the value of A is
The number of cups of sugar for each batch of cookies = 0.4 cups
The number of cookies in 1 batch = 16 cookies
Now , the number of cookies in 4 batches = 4 x 16
The number of cookies in 4 batches = 64 cookies
Now , the number of cups of sugar for 4 batches A = 4 x number of cups of sugar for each batch of cookies
Substituting the values in the equation , we get
The number of cups of sugar for 4 batches A = 4 x 0.4
The number of cups of sugar for 4 batches A = 1.6 cups of sugar
Therefore , the value of A is 1.6 cups
Hence , the number of cups of sugar is 1.6 cups

Because for the first problem you would have to simplify 8 divided by 2 into 4 in which 12 - 4 = 8 then you would have to simplify 12 - 4 to 8 which 8 = 8
Because for the second problem you would have to simplify 12 - 8 to 4 which 4 divided by 2 = 2 then you would have to simplify 4 divided by 2 to 2 which 2 = 2
