Simplify the following fraction:
90/20
Answer:
9/2 simplified
and 4 1/2 as a mixed number
Answer:
Fraction: 9/2
Mixed: 4 1/2
Step-by-step explanation:
We do this by first finding the greatest common factor of 90 and 20, which is 10.
Then, we divide both 90 and 20 by the greatest common factor to get the following simplified fraction:
9/2
Therefore, this equation is true:
90/20 = 9/2
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
9/2 = 4 1/2
The population in Smalltown in 2010 was 45,230 people and is growing exponentially at a rate of 2%. What will the population be in 2030?
A) 67,209
B) 67,475
C) 81,928
D) 82,414
Answer:
Let P(t) = population t years after 2010
= 45230e0.02t
Population in 2030 = P(20)
= 45230e0.4≈ 6747

In a movie theater, the first row contains 3 seats, the second row contains 6 seats, the third row contains 9 seats, and the fourth row contains 12 seats.
A.) Write explicit rule for sequence
B.) Write recursive rule for sequence.
Answer:It's an arithmetic sequence with a common difference, d, = 4
A1 = 8
A2 = 8+4 = 12
A3 = 12+4 = 16 = 8+4(3-1) = 8+4(2) = 8+8
AN = A1 + d(N-1)
AN = 8 +4(N-1) = the Nth term in the sequence

Which quantities appear to be in a proportional relationship?
Answer:
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Find the solution of the system of equations.
2.x + 4y = -14
– 2y = 9
Answer:
x = 4, y = -9/2 (-4.5)
Step-by-step explanation:
Using the second equation, we can divide both sides by -2 and get
y = 9/-2
y = -9/2
Then, we plug this y value into the first equation and get:
x + 4(-9/2) = -14
Simplify:
x - 18 = -14
x = 4
HELP PLS MARKING BRAINLEIST TO CORRECT ANSWER
Answer:
6/3=2
Step-by-step explanation:
its very easy pls give brainliest
Answer:
2
Step-by-step explanation:
Slope=Rise/Run
What does that mean? It means that the slope is equal to the change in y over the change in x.
It can be defined as m=(y1-y2)/(x1-x2)
Let's pick two random coordinates.
Say...
(30,10) and (40,30).
x1=30
x2=40
y1=10
y2=30
So when we plug those in, we get
m= (10-30)/(30-40)
which simplifies to (-20)/(-10)
which simplifies to 2.

28/63 > 27/63
Rahul took more by 1/63
consider the linear function f(x)=4x-5 Find the values of x for which f(x)=3,f(x)=5,f(x)=-3
Answer:
f(2) = 3
f(5/2) = 5
f(½) = -3
Step-by-step explanation:
Given the linear function f(x) = 4x - 5:
f(x) = 33 = 4x - 5
3 + 5 = 4x - 5 + 5
8 = 4x
8/4 = 4x/4
2 = x
Therefore, when f(x) = 3, x = 2.
f(x) = 55 = 4x - 5
5 + 5 = 4x - 5 + 5
10 = 4x
10/4 = 4x/4
5/2 = x
Therefore, when f(x) = 5, x = 5/2.
f(x) = -3-3 = 4x - 5
-3 + 5 = 4x - 5 + 5
2 = 4x
2/4 = 4x/4
½ = x
Therefore, when f(x) = -3, x = ½.

20. Write the following equation in slop intercept form. -4x-3y=-18.
21. Write the following equation in slope intercept form. -2x+3y=21
please show your work and thank you.
Step-by-step explanation:
slope intercept form y=mx+b
you just need to move the letters and numbers around to match this.
-4x-3y=-18
add 4x to both sides of the equal sign
-3y =4x-18
divide by negative 3 on both sides
y = -4/3x + 6
21. -2x+3y=21
add 2x to both sides
3y = 2x + 21
divide by 3 on both sides
y = 2/3x +7

draw an ordered stem and leaf diagram to show infomation 245
Answer:
if asked to find stem leaf 245 scale key then 2 | 45 is what we could show to one side of the diagram.
We then use organise all numbers in numerical order lowest to highest in a horizontal list to copy.
Then draw a vertical line for your stem hopefully it is on lined paper.
single digits 1-9 go right side.
tenths get split keeping digits rights side
hundred units get split keeping tenth and single digits right side
and so forth so that nly the first number of larger numbers is on the left, just first digit. Being the first digit of numbers higher than 9.
Larger numbers that have 3 digits are more than double digits I've called 100th units
Numbers lower than 9 will be on rights side on the first line.
1-9 = 0 | 1 2 3 4 5 6 7 8 9
10-19 1 | 0 1 2 3 4 5 6 7 8 9
20-29 2| 0 1 2 3 4 5 6 7 8 9
100-110 = 1 | 00 01 02 03 etc.. becomes our first 100th line
We use thsi by counting how many numbers we have before drawing and by writing the scale key ie) 1|1 if 11 is shown etc. sometimes just called key.

Solve For x for the remaining problems. You MUST show your work.
Answer:
x = 6
Step-by-step explanation:
All angles of a triangle equal 180
180 - 70 - 60 = 50
8x+2 = 50
x = 6
Answer:
x = 6
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
70 + 60 + 8x + 2 = 180 , collect like terms
132 + 8x = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6

Answer:
On a coordinate plane, a vertical line goes through x = 3.
Step-by-step explanation:
I haven't looked at the other choices, but clearly this is a function
Answer:
will find at bottom
Step-by-step explanation:
A relation is a function of x if each value of x in the domain corresponds to exactly one value of y in the range. In other words, there should be no repeated values of x with different values of y.
Let's analyze each of the given tables to determine which one represents a function of x:
1. Table 1: In this table, we have x values of -1, 2, 2, and 3. Notice that x = 2 appears twice with different y values. This violates the definition of a function, so Table 1 is not a function of x.
2. Table 2: This table has x values of -8, -8, 1, and 1. Similar to the previous table, x = -8 and x = 1 appear twice with different y values. Therefore, Table 2 is not a function of x.
3. Table 3: In this table, all the x values are the same, which is -5. However, the corresponding y values are different (-9, 7, -9, and 2). Since each x value has a unique y value, Table 3 represents a function of x.
4. Table 4: This table consists of x values of -3, -2, 4, and 7. Each x value corresponds to a unique y value (-1, 5, 0, and -1). Therefore, Table 4 also represents a function of x.
To summarize, the relations that are functions of x are Table 3 and Table 4.

Will give brainiest for someone who gives me an explanation if I can
Answer:
x ≤ -12
Step-by-step explanation:
to solve for 'x', since it is getting multiplied by 1/4, you must multiply it by the inverse which is 4
whatever gets multiplied to one side of the inequality must also get multiplied to the other side
you will get:
x ≤ -12
Write the equation of the graph below in slope intercept form.
Write the answer in slope intercept form and please step by step.
(2,1) and (1,3)=
Step-by-step explanation:
so (2,1) (1,3)
x1,y1 x2,y2
so then it would be
the slope is -1
so the equation is after using your x1 and y1 would be
y-1=-1(x-2)
and after you solve that by using the comunitive property, then it will look like
y-1=-1x+2
then you subtract 1 from the y side and make it
the answer is y=-1x+3

hello i need the answer what is the product of 15/16
Answer:
The product is 240.
Step-by-step explanation:
The product is always when you multiply numbers together.
Answer:
Using 15 times table, we have 15 times 8 = 15 × 8 = 120. Hence, 15 times 8 is 120. b) First, we will write 15 times 7 minus 5 mathematically.
Table of 15 up to 20.
15 × 11 = 165 15 × 16 = 240
15 × 14 = 210 15 × 19 = 285
15 × 15 = 225 15 × 20 = 300
