Sarah counted the number of tiles at each step and made a table. She explained that the
number of tiles in each figure was always 3 times the step number minus 2.
Create an equation that fits Sarah's way of seeing the relationship.
PLS HELP DUE IN 10 min!!
Answers
Answer:
n(number of tiles) x 3 - 2
Step-by-step explanation:
times mean multiplication and minus mean subtraction, I hope this helps.
An equation is formed of two equal expressions. An equation that fits Sarah's way of seeing the relationship is y = 3x - 2.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
As stated by Sarah that "the number of tiles in each figure was always 3 times the step number minus 2", this can be written in the form of an equation as shown below.
Number of tiles = [3 × (Number of steps)] - 2
Assume that the number of tiles is represented by y, while the number of steps can be written as x. Therefore, we can write the equation as,
y = 3x - 2
Now, let's check the equation,
When the number of steps is 3, the number of tiles is 7.
y = 3(3) - 2
y = 9 - 2
y = 7
Since the number of tiles is the same, therefore, the equation is correct.
Hence, an equation that fits Sarah's way of seeing the relationship is y = 3x - 2.

The value of a car depreciates every year. Suppose you buy a new car for $17,000, and each year its value is only 90% of what it was the previous year. Write an equation that represents the value of the car, y, after x years.
A.
y=0.90 · 17,000xy equals 0.90 times 17,000 superscript x baseline
B.
y=17,000 · 0.90xy equals 17,000 times 0.90 superscript x baseline
C.
y=17,000 · 0.10xy equals 17,000 times 0.10 superscript x baseline
Answers
B.
y=17,000 · 0.90xy equals 17,000 times 0.90 superscript x baseline
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Since the car’s initial value was $17,000, a = 17,000. Since the car retains 90% of its value each year, b = 0.90.

Step-by-step explanation:
r = 3 ft (that's the radius)
and pi = 3
A = pi r^2
or
3 * r^2
plug in r = 3
so 3 * 3^2 = 3 * 9 = 27 ft^2
(note: 3^2 = 3 * 3. Squaring means we multiply the number by itself)
A=pi•r^2
A=3.14•3^2
A=3.14•9
A=28.26

The value of x is -29.2(x-8) + 4x = 6(x - 2) - 4
Answers
Answer:
They are equal.
Step-by-step explanation:
2(x-8)+4x=6(x-2)-4
Distribute: 2(2•x-2•8)+4x=6(6•x-6•2)-4
2x-16+4x=6x-12-4
Combine Like-Terms: (2x+4x)-16=(-12-4)6x
6x-16=6x-16
Since both sides are equivalent, all numbers are solutions.
The equation 2(x - 8) + 4x = 6(x - 2) - 4 is -16 = -16 which means that
the equation has infinitely many solutions.
We have,
Let's solve the given equation step by step:
2(x - 8) + 4x = 6(x - 2) - 4
Distribute on both sides of the equation:
2x - 16 + 4x = 6x - 12 - 4
Combine like terms on both sides:
6x - 16 = 6x - 16
Subtract 6x from both sides to isolate the constants:
-16 = -16
The equation -16 = -16 is true, which means the given equation is an identity.
This implies that the original equation is true for all values of x; there is no specific value of x that satisfies it.
Therefore,
The equation has infinitely many solutions.

The principle amount will be equal to $100. The correct option is B.
What is simple interest?The straightforward crediting of cash flows related to an investment or deposit is referred to as "simple" interest. Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.
Given that Imani earned $24 in interest after four years on an account that paid 6% simple interest annually.
The principle amount will be calculated by using the simple interest formula.
SI = ( P x R x T ) / 100
24 = ( P x 0.06 x 4 )
P = 24 / ( 0.06 x 4 )
P = $100
Therefore, the principle amount will be equal to $100. The correct option is B.

1 7/8 = (8*1+7)/8 = 15/8
4 1/2 = (2*4+1)/2 = 9/2
15/8 y = 9/2

Add all the data and divide by 2 to get your median
The median of the data set 8, 8, 14, 15, 15, 15.4, 17, 23, 38.5 will be 15.
What is a median?The median of the data is the middle value of the data which is also known as the central tendency of the data and is known as the median.
The data set is given below.
17, 8, 23, 14, 15, 38.5, 8, 15.4
Arrange the data in ascending order, then we have
8, 8, 14, 15, 15, 15.4, 17, 23, 38.5
The number of the term will be 9, then the median will be
Median = (n + 1) / 2
Median = (9 + 1) / 2
Median = 10 / 2
Median = 5th term
5th term that is 15.
The median of the data set 8, 8, 14, 15, 15, 15.4, 17, 23, 38.5 will be 15.
