Helen and Rebecca baked some muffins in the ratio 2:5. After Helen baked another 12 muffins, the ratio become 1:2. How many muffins did Helen bake altogether?​

Answers

Answer:  60 muffins

=========================================================

Explanation:

x = some positive whole number

2x = amount Helen baked initially

5x = amount Rebecca baked initially

Notice that the ratio 2x:5x reduces to 2:5 after dividing both parts by x.

So (2x)/(5x) = 2/5

Helen then bakes another 12 muffins, bumping the 2x up to 2x+12. The ratio is now 1:2, which means,

(amount Helen bakes)/(amount Rebecca bakes) = 1/2

(2x+12)/(5x) = 1/2

2(2x+12) = 5x*1 .... cross multiply

4x+24 = 5x

24 = 5x-4x

24 = x

x = 24

From here, we then can say,

Helen = 2x+12 = 2*24+12 = 48+12 = 60Rebecca = 5x = 5*24 = 120

Helen baked 60 muffins and Rebecca baked 120 muffins. We see that 60:120 reduces to 1:2 after dividing both parts by the GCF 60.

Furthermore, note how

2x = 2*24 = 485x = 5*24 = 12048:120 reduces to 2:5 after dividing both parts by 24

This helps confirm we have the correct answer.

How many solutions does the nonlinear system of equations graphed

Y=-1/64(x-16)^2+4 Y=-1/2x-4

Answers

Answer:

  2

Step-by-step explanation:

The graphs have two (2) points of intersection. Each point of intersection is a solution to the system of equations. The coordinates of that point satisfy both equations simultaneously.

There are 2 solutions to the graphed system of equations.

a system of equations is given below in terms of the scalar parameters a and b.

ax + 2y+ 4z = b

2x +y+3z= a+1

5x-2y+ (a+1)z= 3

(1) Show that if a = -5 or a=2, the system does not have a unique solution.​

Answers

A system of equations only has a unique solution if all the equations are linearly independent (this means that we have two or more equations representing the same curve).

Here we have the system:

a*x + 2*y + 4*z = b

2*x + y + 3*z = a + 1

5*x - 2*y + (a + 1)*z = 3

Now we want to show that if a = -5 or a = 2, then the system does not have a unique solution.

To see this, we can just replace a by these values and see that the equations are not linearly independent.

for a = 2 we get:

2*x + 2*y + 4*z = b

2*x + y + 3*z = 2 + 1

5*x - 2*y + (2 + 1)*z = 3

Simplifying this:

2*x + 2*y + 4*z = b

2*x + y + 3*z = 3

5*x - 2*y + 3*z = 3

From the second and third equation we can write:

2*x + y + 3*z = 3 = 5*x - 2*y + 3*z

2*x + y + 3*z = 5*x - 2*y + 3*z

2*x + y = 5*x - 2*y

3*y = 3*x

y = x

now that we know this, we can rewrite the equations as:

4*(x + z) = b

3*(x + z) = 3

Now we can take the quotient of the two equations to get:

(4*(x + z))/3*(x + z) = (4/3) = b/3

b = 4

Then the equations become:

4*(x + z) = 4

3*(x + z) = 3

Here we can divide te above one by 4 and the below one by 3 to get:

(x + z) = 1

(x + z) = 1

So both equations represent the same line, thus, the system does not have a unique solution.

Now for a = -5:

-5*x + 2*y + 4*z = b

2*x + y + 3*z = -5 + 1

5*x - 2*y + (-5 + 1)*z = 3

Simplify it:

-5*x + 2*y + 4*z = b

2*x + y + 3*z = -4

5*x - 2*y  - 4*z = 3

Now we can rewrite the first equation as:

-5*x +2*y - b = -4*z

and the third one as:

-4*z = 3 - 5*x + 2*y

Then we can write:

-5*x +2*y - b = -4*z = 3 - 5*x + 2*y

-5*x +2*y - b = 3 - 5*x + 2*y

Now we can remove the -5*x in both sides to get:

+2*y - b = 3 + 2*y

Now we can remove the 2*y in both sides to get:

-b = 3

b = -3

Replacing this in our system we get:

-5*x + 2*y + 4*z = -3

2*x + y + 3*z = -4

5*x - 2*y  -4*z = 3

Now we can multiply the first equation by -1:

-1*(-5*x + 2*y + 4*z)= -1*(-3)

5*x - 2*y - 4*z = 3

This is the same as the third equation, so here we can see that the first and third equations represent the same line, thus, the system of equations does not have a unique solution.

This is the same as showing the following system of equations doesn't have a solution:

The quickest way to check if there is a solution is to check whether the coefficient matrix is invertible. If its determinant is 0, then it is not invertible.

And the quickest way to show that the determinant is 0 is by observing that the third row is a linear combination of the first two rows:

(-2, 9, 6) - (-3, 2, 1) = (-2 + 3, 9 - 2, 6 - 1) = (1, 7, 5)

If 4/15 of the candies in a bag of Skittles are red and 3/10 are yellow, what fraction of the bag are red or yellow

Answers

Add the two fractions together but first rewrite the fractions with a common denominator.

4/15 = 8/30

3/10 = 9/30

8/30 + 9/30 = 17/30

Answer: 17/30

The fraction is 17/30.

What is fraction?

fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

For example.

The following figure shows a pizza that is divided into 8 equal parts. Now, if we want to express one selected part of the pizza, we can express it as 1/8 which shows that out of 8 equal parts, we are referring to 1 part.

Given:

4/15 of the candies in a bag of Skittles are red

3/10 are yellow

So, make the denominator of both fraction same by LCM

4/15 = 8/30

3/10 = 9/30

Now,

8/30 + 9/30 = 17/30

Hence, the fraction is 17/30.
