Answer:
9 cups of yellow paint
Step-by-step explanation:
A mixture of paint calls for 1/3 cups of red paint and 3/4 cups of yellow paint.
From the above question
1/3 cups of red paint = 3/4 cups of yellow paint
1 cup of red paint = x cups of yellow paint
Cross Multiply
1/3 × x = 3/4 × 1
x = 3/4 ÷ 1/3
x = 3/4 × 3/1
x = 9/4
x = 2 1/4 cups of yellow paint
Hence, 1 cups of red paint requires 2 1/4 cups of yellow paint
If there were 4 cups of red paint added to the mixture, how many cups of yellow paint would need to be added to keep a constant rate of proportionality?
1 cups of red paint = 2 1/4 cups of yellow paint
4 cups of red paint = x cups of yellow paint
Cross Multiply
x cups of yellow paint = 4 × 2 1/4 cups of yellow paint
= 4 × 9/4 cups of yellow paint
= 9 cups of yellow paint
Therefore, 4 cups of red paint requires 9 cups of yellow paint

The first 5 terms of some sequences are given. State a rule that each sequence could follow.
2, 4, 6, 8, 10
5, 7, 9, 11, 13
50, 25, 0, -25, -50
1/3, 1, 3, 9, 27
The first , second and third sequence is arithmetic and the fourth sequence is geometric.
A sequence is a series of numbers such that each number follows a very specific rule or explicit function which determines its value. There are numerous types of sequence and series . But for this particular question we will need to know :
Arithmetic sequence : Number in an arithmetic sequence or AP are at equal distance from each other if plotted on a number line. The difference between any two consecutive numbers is the same and it is called the common difference.Geometric sequence : a sequence of numbers is said to be in a GP such that the ratio of each number to the preceding and the succeeding numbers is same.Let us now take each series of numbers and find the type of sequence it is:
sequence 1: 2, 4, 6, 8, 10
Common difference = 10-8 = 6-4 =2
So the sequence is arithmetic.
sequence 2: 5, 7, 9, 11, 13
Common difference = 13-11 = 7-5 =2
So the sequence is arithmetic.
sequence 3: 50, 25, 0, -25, -50
Common difference = 50-25 = - 25 - ( - 50) = 25
So the sequence is arithmetic.
sequence 2: 5, 7, 9, 11, 13
Common difference = 13-11 = 7 - 5 =2
So the sequence is arithmetic.
sequence 2: 1/3, 1, 3, 9, 27
Common ratio = 3 ÷ 1 = 27 ÷ 9 = 3
So the sequence is geometric.

Can some one help me graph y=4x + 5 I keep doing something wrong.
Answer:
y = - 3x + 4
Step-by-step explanation:
Line is passing through the points (1, 1) & (0, 4)
Slope of line = (4-1)/(0-1) = 3/(-1) = - 3
Equation of line
y = mx + b
Here m = - 3, b = 4
y = - 3x + 4
Using point (1, 1)
y - 1= - 3(x - 1)
y = - 3x +3 +1
y = - 3x + 4
A bakery used 25% more butter this month that last month. If the bakery used 240 kilograms of butter last month, how much did it use this month?
Answer:
300kg
Step-by-step explanation:
240(25/100)
240(.25) = 60
25% of 240 = 60, so add that 60 to get an extra 25% for this month
240 + 60 = 300

Which are correct representations of the inequality 6x2 3 + 4(2x - 1)? Select three options.
Answer:
Option A, B, and C.
Step-by-step explanation:
Given, 6x ≥ 3 + 4(2x - 1),
Solve to find the correct representations given in the options.
6x ≥ 3 + 4(2x - 1)
Apply distributive property
6x ≥ 3 + 8x - 4 (option B is correct) ✅
Add like terms
6x ≥ -1 + 8x
Add 1 to both sides
6x + 1 ≥ 8x
Subtract 6x from each side
1 ≥ 8x - 6x
1 ≥ 2x (option A is correct) ✅
Divide both sides by 2
1/2 ≥ 2x/2
½ ≥ x
½ ≥ x means all possible values of x are less than 0.5. representing this inequality on a graph, we would have the directed line starting at 0.5 moving towards our left.
This make option C correct.✅

y= 8-2x tell the answer with explanation
The equation has infinite solutions which lie on the graph of this equation.
We have the following equation -
y = 8 - 2x
We have to solve for the possible values of x and y for which the equation is satisfied.
Define rearrangement of a mathematical equation.The rearrangement of a mathematical equation is process of expressing a variable in a equation in terms of other variables, constants etc.
According to the question, we have the following equation -
y = 8 - 2x
Rearranging the equation -
y = - 2x + 8
Now, plot the equation on graph - (Graph is attached at the end)
All the coordinates on this line satisfy the equation → y = 8 - 2x.
Hence, the equation has infinite solutions which lie on the graph of this equation.

What is the radius and diameter of the following circle?

Report a probl
st
Answer:
radius=9cm
diameter=18cm
Step-by-step explanation:
Answer:
Radius = 9cm
Diameter = 18cm
Step-by-step explanation:
Remember that the diameter of a circle is the distance between two opposite sides (crossing the middle), and the radius is half of that - the distance from the middle to the outside.
the image shows that the diameter is 18cm, so we know that the radius is 18cm/2, which equals 9cm.

Answer:
x=19/2
x=- 13/2
Step-by-step explanation:
multiply both sides by 2 |2x -3|+10=26
move constant (10 to the right and change sign |2x-3|=26-10
subtract the numbers |2x-3|=16
use absolute value (rewrite the absolute value 2x-3=16
equation as two separate equations one (+) and (-) 2x-3= -16
2x-3=16 move constant to the right
2x=16+3 add the numbers
2x=19 divide both sides by 2
x=19/2
same steps with with second one
2x-2= -16
2x= -16 +3 move constant to the right change sign and add
2x= -13 divide both sides by two
x= -13/2

What is the value of x in the equation
5(2x-7)=15x-10?
Answer:
x = -5
Step-by-step explanation:
First distribute the 5 on the right side of the equation.
10x - 35 = 15x - 10
Then subtract 10x on each side
-35 = 5x - 10
Then add 10 on each side
-25 = 5x
Divide 5 on each side to get x
-25 / 5 = -5
