440 bevause 154 is 35 percent of 440
The 154 mocha cupcakes represents a proportion of the total cupcakes sold in the bakery. The total number of cupcakes sold in the bakery on that day is 440.
Given that:
[tex]Mocha = 154[/tex]
From the question, we understand that the bakery sells other cupcakes too.
And Mocha only represents 35% of the total.
This means that:
[tex]Mocha = 35\% \times Total[/tex]
So, we have:
[tex]154 = 35\% \times Total[/tex]
Make Total the subject
[tex]Total = 154 \div 35\%[/tex]
[tex]Total = 440[/tex]
Hence, 440 cupcakes were sold on that day.

Matteo has &400 in his saving account. On average he spends $10 per week on buying apps. Luca has $200 in his savings account. He is saving $15 a week in order to buy a new Playstation. When will matteo and luca have the same amount of money?
Answer: By the 8th week.
Step-by-step explanation:
Let the time that matteo and luca have the same amount of money be represented by x.
The information given in the question can be formed into an equation as:
400 - 10x = 200 + 15x
Collect like terms
400 - 200 = 15x + 10x
200 = 25x
x = 200/25
x = 8
Matteo and Luca will have the same amount of money by the 8th week.

y=5−x2y is equal to 5 minus x over 2
x−3y=3x minus 3 y is equal to 3
8y=6x8 y is equal to 6 x
y=6x
Answer: x-3y=3x
8y=6x8
y=6x
Step-by-step explanation:
Meaning of linear equationA linear equation is a equation that goes at a constant pace and won't change overtime, so functions like x squared and functions that multiply x and y together doesn't go at a constant pace, there not linear equations, but functions like y=mx, M representing any constant, that is a linear equation, therefore x-3y=3x8y=6x8
y=6x
Are the answers to your Question,The equations that represent linear functions are x − 3y = 3x and y = 6x , so options D and E are correct.
What is a linear equation?A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line. Functions like y = mx, where m can be any constant, are considered linear equations.
The given equations,
y = −x² + 4y, y = 5 − x²y, 8y = 6x⁸y on solving get a degree more than 1 then the equation is a linear function, only
x − 3y = 3x
3y = -2x and y = 6x have degree one, so they are linear

Write the equation of the circle with a center at (11,6) and a radius of 6.
Answer:
(x-11)^2 + (y-6)^2= 6^2
Step-by-step explanation:
Answer:
(x - 11)² + (y - 6)² = 36
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (11, 6 ) and r = 6, then
(x - 11)² + (y - 6)² = 6² , that is
(x - 11)² + (y - 6)² = 36

complete the equation of the line whose slope is -2 and y intercept is (0,3)
Answer:
y = -2x+3
Step-by-step explanation:
This is assuming you want the answer in slope-intercept (y = mx+b)
You need to know:
y = The line
m = The slope
b = The y-intercept
Step 1, replace the slope (m):
y = -2x+b
Step 2, replace the y-intercept (b):
y = -2x+3
Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3

find the value of n
1/4(2n +6) = 4
Answer:
n=5
Step-by-step explanation:
1/4(2n +6) = 4
Multiply each side by 4
4*1/4(2n +6) = 4*4
(2n +6) = 16
Subtract 6 from each side
2n+6-6 = 16-6
2n = 10
Divide each side by 2
2n/2 = 10/2
n =5
Answer:
n= 5
Step-by-step explanation:
Hello! So to find the value of n, we just multiply 1/4 by the numbers inside the parentheses and then solve for n by dividing. Let's do it!
1/4 (2n + 6) = 4
0.5n + 1.5 = 4
0.5n = 4 - 1.5
0.5n = 2.5
n = 2.5 / 0.5
n = 5

What is a word problem?
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The Simon's salary at present = $35730.40 p.a.
Increased rate = 6% = 0.06
(a) Simon's salary three years ago:
⇒ [tex]\$35730.40(0.06)[/tex]
⇒ [tex]\$2143.824[/tex]
Original salary of Simon,
⇒ [tex]35730.40-2143.824[/tex]
⇒ [tex]\$33586.576[/tex]
(b) Gross monthly salary at the present:
⇒ [tex]\frac{33586.57}{12}[/tex]
⇒ [tex]2798.88[/tex]
(C) Net pay per month:
Deductions each month amount to 22.5% of his gross salary,
⇒ [tex]22.5\%=0.225[/tex]
⇒ [tex]2798.88(0.225)[/tex]
⇒ [tex]\$629.79[/tex]
Thus net pay per month,
⇒ [tex]2798.88-629.79[/tex]
⇒ [tex]\$2169.09[/tex]
Hence we can conclude that
(a) Simon's salary three years ago is $33586.576.
(b) Gross monthly salary at the present is $2798.88.
(C) Net pay per month is $2169.09.

Which angles are complementary to each other? Select all that apply.
The complementary angles are ∠1 and ∠5. The correct option is D.
What are complementary angles?Complementary angles are two angles whose measures add up to 90 degrees. In other words, if angle A and angle B are complementary, then:
A + B = 90 degrees
A = 90 - B
B = 90 - A
For example, if angle A measures 30 degrees, then angle B would measure 60 degrees to make a complementary pair. Complementary angles are often used in geometry and trigonometry to solve problems involving right triangles and other geometric shapes.
The two angles ∠1 and ∠5 have the sum of 90°. These angles are complementary to each other.

which graph shows the solution to the system of equations?y =-2x+1 and y =-3/2
Answer:
(1.25, -1.5)
Step-by-step explanation:
The system of equations:
y = -2x + 1
y = -3/2
So we know that the two lines meet at the point where y = -3/2 = -1.5
∴ -1.5 = - 2x + 1
2x = 1 + 1.5 = 2.5
x = 2.5 ÷ 2 = 1.25
So the solution to this system of equation (or where the two lines meet) is the point (1.25, -1.5)
