Answer:
[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]
Step-by-step explanation:
Represent white paint with w and black with b
Given
When w = 3; b = 1
Required
Determine the two equations
To get a gray paint, the w and b are needed in the following proportion:
[tex]3 * w = 1 * b[/tex] -----(1)
Solve for b
[tex]3 * w = b[/tex]
Reorder
[tex]b = 3 * w[/tex]
[tex]b = 3w[/tex] ---- This is an equation
To get another equation,
Recall that
[tex]3 * w = 1 * b[/tex]
Solve for w
[tex]3*w = b[/tex]
[tex]3w = b[/tex]
Make w the subject
[tex]w = \frac{1}{3}b[/tex]
Hence, the equations that show the relationship between w and b are:
[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]
what is the slope of the line passing through the points (-3,4) and (2, -1)
Answer:
slople = -1
Step-by-step explanation:
(x₁ , y₁) = (-3, 4) & (x₂ , y₂) = (2 , -1)
[tex]slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\frac{-1-4}{2-[-3]}\\\\\\=\frac{-1-4}{2+3}\\\\\\=\frac{-5}{5}\\\\= -1[/tex]

find the ordered pair for the solution -7x+3y=2
Answer:
(1, 3 )
Step-by-step explanation:
To find a solution choose a value for x, substitute into the equation and solve for y.
let x = 1 , then
- 7(1) + 3y = 2 , that is
- 7 + 3y = 2 ( add 7 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
One possible solution is therefore (1, 3 )

Liya has one 30-ounce jar of pink paint.The ratio of white paint in the jar is 3:7, Liya doesn't like the shade pink so she moves the paint into a 128-ounce container and adds more white and red paint to fill the container.If the new ratio of white paint to red is 3;5 how many more ounces of white paint does she add to make the new shade of pink paint?
Answer: 8
Step-by-step explanation:
8x0
The required amount of ounces of white paint added is 35.15 ounces.
Given that,
Liya has one 30-ounce jar of pink paint. The ratio of white paint in the jar is 3:7, Liya doesn't like the shade pink so she moves the paint into a 128-ounce container and adds more white and red paint to fill the container. If the new ratio of white paint to red is 3:5.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Ounces of white paint in a 30-ounce jar,
= 30 × 3 / 7 = 12.85,
Ounces of white paint in 128-ounce of the jar,
= 128 × 3 / 8 = 48
The number of ounces of white paint added = 48 - 12.85 = 35.15
Thus, the required amount of ounces of white paint added is 35.15 ounces.

Answer:
83
Step-by-step explanation:
Answer:
x = 59
y = 83
Step-by-step explanation:
First, you need to solve for y in order to solve for x. Using the Triangle Sum Theorem, you will find that y is 83 degrees.
Now, using the Vertical Angles Theorem, you can figure out the third angle of the triangle in which x is, 83.
Using the Triangle Sum Theorem again, you will find that x is 59.

Sophia bought 9 red peppers for $5.40.
PLEASE HELP
Find the unit rate. Then use the unit rate to write an equation relating the cost in dollars c to the number of red peppers p.
Answer:
$0.60/each
Step-by-step explanation:
$5.40/9=0.60 Total price *($5.60) divided by 9 (PEPPERS) = $0.60
c= 0.6p
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Cost of 9 red peppers = $5.40
Cost of 1 red pepper = 5.40 /9
= 0.6

Food bill before tax $45 sales tax 6.8% tip 24%
Answer:
The total bill is $58.86
Step-by-step explanation:
Percentages
Before tax, the food bill is $45. Sales tax is 6.8% and the tip is 24%.
Tax is 6.8*$45/100 = $3.06
Tip is 24*$45/100 = $10.80
Total additional charges are:
$3.06+ $10.80= $13.86
Thus, the total bill for the food is:
$45 + $13.86 = $58.86
The total bill is $58.86

Let the measure of the other interior angle = M
The exterior angle is equal to the sum of the interior angles in a given triangle.
An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.
This means,
M + 20 = 80
Solve for M.
M + 20 = 80
Subtract 20 on both sides.
M = 80 - 20
M = 60
Thus,
The measure of the other remote interior angle is 60°.

Q 1: You are making chocolate chip cookies. The recipe calls for 1/8 teaspoon salt to 1/4 teaspoon baking soda. How much baking soda is needed for 1 teaspoon of salt?
Q 2:Use the information contained within the question one. How much salt is needed for 1 teaspoon of baking soda?
Answer:
x = teaspoon of soda needed = 2 teaspoons of baking soda for 1 teaspoon of salt
y = teaspoons of baking soda needed = 1/2 teaspoons of salt needed for 1 teaspoon of baking soda
Step-by-step explanation:
Teaspoon of salt : Teaspoon of soda
1/8 : 1/4
How much baking soda is needed for 1 teaspoon of salt?
Let
x = teaspoon of soda needed
Teaspoon of salt : Teaspoon of soda
1 : x
Equate both proportion
Teaspoon of salt : Teaspoon of soda
1/8 : 1/4 = 1 : x
1/8 ÷ 1/4 = 1/x
1/8 × 4/1 = 1/x
4/8 = 1/x
Cross product
4*x = 8*1
4x = 8
x = 8/4
= 2
x = 2 teaspoons of
x = teaspoon of soda needed = 2 teaspoons for 1 teaspoon of salt
2. How much salt is needed for 1 teaspoon of baking soda?
Let y = teaspoons of baking soda needed
Teaspoon of salt : Teaspoon of soda = y : 1
Equate the proportion
1/8 : 1/4 = y : 1
1/8 ÷ 1/4 = y / 1
1/8 × 4/1 = y / 1
4/8 = y / 1
Cross product
4 * 1 = 8 * y
4 = 8y
y = 4/8
= 1/2
y = 1/2 teaspoons of baking soda
y = teaspoons of baking soda needed = 1/2 teaspoons needed for 1 teaspoon of baking soda
