Answer:
if she has to buy from a mixture of both the cheeses then equation will become;
N x C + M x S = 30
Explanation:
Let C represents the value of cheddar cheese per pound
Let S represents the value of swiss cheese per pound.
Equation when she only buys cheddar cheese will be;
N x C = 30,
Here N is the number of pounds of cheddar cheese
Equation when she only buys swiss cheese will be;
M x S = 30,
Here M is the number of pounds of swiss cheese
Now if she has to buy from a mixture of both the cheeses then equation will become;
N x C + M x S = 30

A bike path starts on one side of the parking lot, goes around a small pond, and comes out on the other end of the parking lot. Following the path, a biker rides 100.0 meters directly east, then turns south and rides 200.0 meters. From there, she turns and rides 150.0 meters at an angle of 30.0° south of west. Turning one last time, she rides 250.0 meters at an angle of 60.0° north of west. What is her final displacement (distance and direction) from her starting point?
A cyclist rides 5.0km due east, then 10.0km20° west of north. From this point she rides 8.0km .

Step-by-step explanation:
make a the subject a + 2b = 3c
Answer:
a = -2b + 3c
Step-by-step explanation:
Step 1: Subtract 2b from both sides.
[tex]a + 2b - 2b = 3c - 2b[/tex] [tex]a = -2b + 3c[/tex]Therefore, the answer is a = -2b + 3c.

question is in image, and answer choices are here:
5, 4, 8, 10
Answer: x is equal to 4
Step-by-step explanation:
A triangle's angles sums up to 180°. So we already know that the three angles in this triangle add up to 180°. The equation would be as following.
(18x - 12) + 15x + (10x + 20) = 180
We first add like terms together.
43x + 8 = 180
We then substract 8 on both sides.
43x = 172
We finally divide 43 on both sides.
x = 4
The sum of negative eight and a number divided by four is two
Answer:
x = 16 or [tex]\frac{-8 + x}{4} = 2[/tex]
Step-by-step explanation:
let's start from the beginning and move along!
the sum (+) of negative eight (-8) and a number (x) ----> (-8 + x)divided by four (/4) is two = 2[tex]\frac{-8 + x}{4}[/tex] = 2
to solve this...
1) multiply both sides by four to get rid of the fraction
[tex](4)\frac{-8 + x}{4} = 2(4)[/tex] ------> -8 + x = 8
2) add 8 to both sides to isolate x ----> x = 16

Which of the following is NOT an equivalent expression to Area of sector =
Answer:
Step-by-step explanation:
From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.
What is the area of a circular sector?The area of the circular sector is the space occupied by it. The area of the circular sector is the half of the product of the angle of the sector and the radius of the circle. It can be given as,
[tex]A_s=\dfrac{r^2\theta}{2}[/tex]
Here, (r) is the radius of the circle and θ is the angle of the sector. Multiply with π/180 to convert it into the degrees.
[tex]A_s=\dfrac{r^2\theta}{2}\left(\dfrac{\pi}{180}\right)\\A_s={\pi r^2}\left(\dfrac{\theta}{360}\right)[/tex]
Thus, the option D is correct. Now, πr² is the area of circle . Thus,
[tex]\rm \text{Area of sector}=\dfrac{(Area\; of \;Circle)(Arc\; Measure)}{360^o}\\\rm \dfrac{(Area\; of \;Sector)}{(Arc\; Measure)}=\dfrac{\text{Area of sector}}{360^o}[/tex]
From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

Find the measures of two supplementary angles if their measures are given in the given ratio
11:25
Solution :
Let the measure of the supplementary angles be 11x and 25x
According to the question :
[tex] \tt \: 11x + 25x = 180 {}^{ \circ} \\ \\ \\ \tt \dashrightarrow \: 36x = 180 {}^{ \circ} \\ \\ \\ \tt \dashrightarrow x = \frac{180{}^{ \circ} }{36} \\ \\ \\ \: \: \: \: \: \: \: \dashrightarrow \: { \underline{ \boxed{ \mathfrak{ \pmb{ \purple{x = 5}}}}}} \: \: \pink{\bigstar} \\ \\ [/tex]
So the required angles are :
11x = 11 × 5 = 5525x = 25 × 5 = 125a variable x has a normal distribution with mean 54 and standard deviation 5. approximately what percentage of the observations will fall between 44 and 64?
For a normal distribution with mean 54 and standard deviation 5 95.4% of them fall between 44 and 64
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean.\sigma=standard\ deviation, x=raw\ score\\\\Given\ that\ mean(\mu)=54,standard \ deviation (\sigma)=5\\\\For\ x=44:\\\\z=\frac{44-54}{5}=-2\\\\For\ x=64:\\\\z=\frac{64-54}{5}=2[/tex]
Therefore., from the normal distribution table:
P(44<x<64) = P(-2< z < 2) = P(z < 2) - P(z < -2) = 0.9772 - 0.0228 = 0.9544
Hence, About 95.4% of them fall between 44 and 64.

1) Factorise 3x^2 + 5x + 2
2) Hence, solve x^2 + 5x + 2
Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)

A cricket pitch measures 1 chain by 10 feet. What is the area of a cricket pitch in square feet?
Answer:
660 square feet
Step-by-step explanation:
1 chain = 66 feet
Length ( l ) = 66 feet
Breadth ( b ) = 10 feet
To find :
The area of a cricket pitch in square feet = ?
The area of a cricket pitch in square feet will be in the shape of rectangle.
Formula : -
Area of a rectangle = lb
Area of a rectangle
= 66 x 10
= 660 square feet
Therefore,
660 square feet is the area of a cricket pitch.

solve the following equations
63= 12x -21
Answer:
X=7
take the -21 to the other side of the equation, when you do this it goes from a negative to a positive so we now have 63+21=12x
if we add 63 and 12 we get 84 decide by 12 because we have 12x and we get 7
