A bakery sells chocolate, cinnamon, maple, honey, and jelly donuts. It currently has
48 total donuts in stock. If Xiwen picks one donut from the bakery at random, she
has a 1/4 chance of picking a chocolate donut. How many chocolate donuts does
the bakery have in stock?
Answers
Since the bakery has only 48 donuts in stock and Xiwen has a 1/4 chance of picking a chocolate donut, there are a dozen (12) chocolate donuts in stock.
1/4 = 0.25
0.25 x 48 = 12
What is the solution to the system of linear equations? Show your work using either substitution or elimination.
Problem:
3x-2y=7
y=x+2
please tell me how you got the answer.
Answers
Answer:
3x - 2y = 7
Where y = x + 2
3x - 2(x + 2) = 7
3x - 2x - 4 = 7
x = 11
Step-by-step explanation:
If you are solving for X and y = x+2 then you write the equation out like this.
3x - 2(x +2) = 7 …. You substitute the x + 2 for y and then solve for x.
2x - 2 times x + 2 times - 2 = 7. That becomes 3x - 2x - 4 = 7. You then subtract 2x from 3x to give you X. Then you add 4 on one side to zero it out and add 4 to the other side. 7 + 4 = 11. This gives you the answer X = 11.

Assume y=5x and dx/dt = 2 find dy/dt
Answers
Answer: 10
Step-by-step explanation: since dx/dt = 2, you have to create an equation. dx/dt = dy/dt * dx/dy is your equation. now we substitute. 2 = dy/dt *dx/dy. find the derivative of 5x in terms of y (dx/dy), which is 1/5. so now your equation is 2 = dy/dt * 1/5. solve for dy/dt and your answer is 10.

In a certain arithmetic sequence, consecutive terms have a positive common difference. The first 4 terms of the sequence have a sum of 80. Which of the following values CANNOT be thefirst term of the arithmetic sequence?
a - 10
b - 12
c - 16
d - 18
e - 20
Answers
Answer:
E:20
Step-by-step explanation:
I had the same question and it correct answer was E.
The first term of the arithmetic sequence will be 20. Then the correct option is E.
What is an arithmetic sequence?Arithmetic succession or arithmetic sequential is a numerical series in which the difference between subsequent terms is uniform.
In a specific number juggling grouping, successive terms have a positive normal distinction. The initial 4 terms of the grouping have an amount of 80.
Let the four terms be a - 3d, a - d, a + d, and a + 3d. Then the sum of the four-term is given as,
a - 3d + a - d + a + d + a + 3d = 80
Simplify the equation, then we have
a - 3d + a - d + a + d + a + 3d = 80
4a = 80
a = 80 / 4
a = 20
The first term of the arithmetic sequence will be 20. Then the correct option is E.
More about the arithmetic sequence link is given below.

Answer:
-5 / 11 or -0.455
Step-by-step explanation:
this is a very simple question that does not need much complexity about it
we have
4( 6x + 5 ) = 2x + 10
first of all, we open the bracket;
24x + 20 = 2x + 10
now, we have to collect like terms;
24x - 2x = 10 - 20
22x = -10
divide through by 22 to give us!
22x / 22 = -10 / 22
x = -5 / 11
therefore,
x = - 5 / 11
hope that helps
thank you
