Answer:
You must be in 8th grade?
Step-by-step explanation:
For the first one I don't know.
The second one I'm also not sure about.
The third one, the answer is 225 because you will divided 150 by 2 and get the answer of 75 and then multiply 75 by 3 to get the answer of 225.
For the fourth one, you will multiply 5 x 2.5 = 12.5 then you will multiply 12.5 x 20 = 250yd^2.
For the last one you will multiply 2.25 x 22 = 49.5 miles.
Rule 1: Multiply by 2 then add 1 starting from 1. Rule 2: Divide by 2 then add 4 starting from 40.
first I start with 1 and multiply 2 =2 and add 1 =3
so on
start with 40 divided by 2 =20+4=24
The sum total of the sequence would be 45, using the two steps given.
What is Algebra?This refers to the use of mathematics to solve equations and letters represent numbers.
Although your sequence is incomplete because it only gave two steps, I would work with only those steps.
Hence, if the first number is 1,
Multiply by 2, 1 x 2= 2
DIvide by 2, 2/2= 1
Add 4, starting from 40.
1+44= 45.

∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.
What are parallel lines?Parallel lines represent coplanar endless straight lines in geometry that never intersect. Within a single three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Euclid's parallel postulate deals with parallel lines. Euclidean geometry is indeed a particular example of this sort of geometry, and parallelism is essentially a feature of affine geometries.
∠1 and ∠4 are corresponding angles has the same shape and size
∠1 and ∠3 are diagonal from each other

366/12
30.5
Median is the middle of the data points.
Line data points up in order from least to greatest.
29,30,30,30,30,31,31,31,31,31,31,31
12/2=6
Since there is an even amount data points the median is the mean of the two middle data points:
Middle data points: 31,31

A bad contains 15 balls of which X is red. Write an expression for the probability that a ball drawn from the bad is red. When 5 more red balls are added to the bag, the probability becomes 3/4. Find the value of X.
Answer:
10
Step-by-step explanation:
The current probability of picking a red ball is [tex]\frac{x}{15}[/tex]. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:
[tex]\frac{x+5}{15+5} = \frac{3}{4}[/tex]
When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).
60 = 4x + 20
40 = 4x
x = 10 red balls

Answer:
The values that are in the correct spots are: 82, 62, 163 and 300
Step-by-step explanation:
There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.
82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.
62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.
156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.

Answer:
y = -5x - 3
Step-by-step explanation:
To answer this the slope must be clculated first
slope equation:
[tex]\frac{y2-y1}{x2-x1}[/tex]
these variables symbolize ordered pairs, and the best part is that you can use any two ordered pairs for this example we can use (-5, 10) and (-3,0)
we'll call the first ordered pair 1 so x1 = -5 and y1 = 10.
the next odered pair is 2 so x2 = -3 and y2 = 0.
With this information layed out we can solve:
[tex]\frac{0-10}{-3-(-5)}[/tex]
0 - 10 = -10
-3 - (-5) = 2 --- remember negatives cancel each other out to make a positive
[tex]\frac{-10}{2}[/tex] = -5
the slope of the line is -5. Now the next thing to note is that one of the ordered pair (-3,0) is a y intercept. It's time to introduce the equatione of a line:
y = mx+b
There are other equations that can be used for a line but with the info given this equation best suits the data.
m = slope
y and x = are the ordered pair you can input into the equation to slove
b = the y intercept
So the equation would be:
y = -5x - 3

Michiko claims that to solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, instead of multiplying the second equation by –2 and then adding the equations, she could multiply the second equation by 2 and then subtract the second equation from the first equation. Which statement is correct?
A: Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations.
B: Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations.
C: Michiko is wrong because her method will give the opposite of the correct value for x for any system of linear equations.
D: Michiko is wrong because her method will give the opposite of the correct value for y for any system of linear equations.
Answer: B) Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations

Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, Michiko suggests multiplying the second equation by 2 and then subtracting the second equation from the first equation.
Multiplying the second equation by 2 gives:
42x + 8y = -26
Now, subtracting the second equation from the first equation gives:
15x + 8y - (42x + 8y) = 1 - (-26)
Simplifying this equation gives:
-27x = 27
Divide both sides by 27
x=-1
we can substitute x = -1 into either of the original equations.
Using the first equation, we get:
15(-1) + 8y = 1
Simplifying this equation gives:
8y = 16
Dividing both sides by 8 gives:
y = 2
Hence, Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

B. y = 2x + 1
C. y = 1/2x - 5
D. y = 1/3x to the power of 2
E. y = -x
Answer:
B, C, and E
The reason B, C, and E are the answer's is because the equation of a linear equation is y= mx+b. B, C, and E are written this way. We can eliminate A and D because They are quadratic equations, because the X is squared.

fill in teh blanks 9516 / 4
Answer:
2,379 & look below for remaining numbers
Step-by-step explanation:
The divisor 4 goes to the left of the whole box, because you are dividing all the numbers by 4.
So for the last box, 4 x 9 = 36
For the top of the 3rd box, it's 4 x ? = 280, so you do 280 divided by 4 = 70
For the 2nd box, 4 x 300 = 1200
For the 1st box, I did the problem of 9516 divided by 4 in long division form. 4 goes into 9 only 2 times & the 2 is in the thousands place. So on top of the 1st box goes 2,000 & in the box goes 4 x 2,000 = 8,000.
Add 8,000 + 1,200 + 70 + 36 = 9,516
9,516 divided by 4 = 2,379
2,000 + 300 + 70 + 9 = 2,379

An average adult giraffe is 18 feet tall. A newborn giraffe is about 6 feet tall/ Kayla is building a model of a mother giraffe and her newborn. She wants the model to be no more than 17 inches high.
Answer:
Mother = 17 inches and then Newborn = 5 (2/3) or 5.66666666667 inches
Step-by-step explanation:
I was sort of guessing based on your question what you were looking for. How I solved this is we know that since the average adult giraffe is 18 feet tall and the average newborn giraffe is 6 feet tall, then the adult giraffe is about 3 times as tall as the average newborn giraffe so the ratio is 3:1 adult: newborn. So with the mother at 17 inches, then since the newborn giraffe is, on average, 3 times smaller than the mother, it is therefore 17/3 = 5.666667 or 5 and 2/3s.
