An equation that models the balance y after x months​ y = 1070 - 172.5x.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Zachary purchased a computer for $1070. The first step is to calculate the purchase he paid after 2 months.

= 1070 - 725

= $345

Then the purchase after 1 month is

= $345/2

= $172.5 per month

The equation can be written as:-

y = mx + c

y = 1070 - 172.5x.

Given,

$14.59+ $5.83 + $0.89

Whole no. is 0,1,2..

If we add these number we get 21.31 is 21

When rounding numbers, there are several basic guidelines that must be observed.

We must first determine our rounding digit. This is the digit that will be affected in the end.

Following that, we must examine the digit to the right of this location, which will determine the fate of the rounding digit.

We do not modify the rounding digit if the digit to the right is less than 5. All digits to the right of the rounding digit, however, are altered to 0.

If the digit to the right is 5 or greater, the rounding digit is increased by one, and all digits to the right of the rounding digit are converted to 0.

Answer: 5x+6y=13

               6x-12y=14

Answer:

AM= 2x+4

MB= 5x-8

AB= ?

So to get AB, you would need to find the total measurements of AM and MB.

AM=MB

2x+4=5x-8

2x=5x-12

-3x=-12

x=4

So now to find the measurement of AB, you need to plug it into AM and MB.

2(4)+4+5(4)-8= 24!!!

So the measure of AB would be 24.

In linear equation ,the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.

What is linear equation?

Using the concept of proportional relationship, the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.

Using the concept of proportional relationship :

For Evian :

1.5 miles = 15 minutes

1 mile = x

1.5x = 15

x = 15 / 1.5

x = 10 minutes

For Toby :

2/3 miles = 6 minutes

1 mile = x

2/3x = 6

x = 6 ÷ 2/3

x = 9 minutes

For J :

0.75 miles = 9 minutes

1 mile = x

0.75x = 9

x = 9 / 0.75

x = 12 minutes

Therefore, the time taken by Evian, Toby and J are 10, 9 and 12 minutes respectively.

2 determine the area of the rectangle at the bottom of the rectangular prism

3 determine the total surface area (TSA) of the rectangular prism.

Step-by-step explanation:

Given that

To find

So, according to the question

Let's assume,

height = h = 15cm

length = l = 2cm

width = w = 5cm

So, from question,

    Area of rectangle in front = 15 cm x 5 cm

That's mean

   Rectangle in front have h = 15cm and l = 5cm.

We know the width from question w = 2cm.

So,

   Area of the rectangle to the left = h x w

                        = 15 x 2

                        = 30 cm²

Also,

 There is no height to the rectangle at the bottom.

So, l and w make up the bottom rectangle.

Now,

the area of rectangle at the bottom  = l x w

                        = 5 x 2

                        = 10 cm²

Now,

  The total surface area (TSA) of the rectangular prism = 2(lw + wh + lh)

                        = 2 ( 75 + 10 + 30)

                        = 2 x (115)

                        = 230cm²

Answer:

2years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year.

I = P × R × T/100

Solving our equation:

$350 = $3500 × 4 × T /100

Let's solve your equation step-by-step.

350=(3500)(4)t/100

Step 1: Multiply both sides by 100.

350=(3500)(4)t/100

(350)*(100)=((3500)(4)t/100)*(100)

35000=(3500)(4)t

Step 2: Simplify both sides of the equation.

35000=14000t

Step 3: Flip the equation.

14000t=35000

Step 4: Divide both sides by 14000.

14000t/14000=35000/14000

t=5/2

t = 2.5 years

2.5 years = 2years 6 months

Answer:

Try no solution

Step-by-step explanation:

Solving for the solution the answer is 4

Solving for x the answer is no solution

The solutions of the linear equations are below:

(1/3)*x + 7 = 3 + (2/3)*x  is true if x = 12

5r−8=9r−12   is true if r = 1

(5/9)t− 27 = (1/9)t + 21   is true if t = 108

−(1/2)(−5y+4) = 2 + 1/2y  is true if y = 2.

a) The first linear equation we have is:

(1/3)*x + 7 = 3 + (2/3)*x

To solve this, move all the like terms together (I will move the ones with x to the left side and the ones without x to the right side).

(1/3)*x - (2/3)*x = 3 - 7

Now we just simplify:

-1/3*x = -4

Now we isolate x:

x = -3*-4 = 12

x = 12

That is the solution of the linear equation, so remember, you just need to isolate the variable.

Let's do the same for the other ones:

2) 5r−8=9r−12

5r - 9r = -12 + 8

-4r = -4

r = -4/-4 = 1

r = 1

3)  (5/9)t− 27 = (1/9)t + 21

(5/9)*t - (1/9)*t = 21 + 27

(4/9)*t = 48

t = (9/4)*48 = 108

4) −(1/2)(−5y+4) = 2 + 1/2y

Here we start by expanding the product in the left side, we will get:

(5/2)*y - 2 = 2 + (1/2)*y

(5/2)*y - (1/2)*y = 2 + 2

(4/2)*y = 4

2*y = 4

y = 4/2 = 2

y = 2

And so on, that is the general method to solve linear equations, just isolate the variable in one side of the equation and simplify the other side.

The probability that it has a mass of more than 120 g is 13/40.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.

Given,

frequency = 5   9   13   7   6

sum of frequency = 40

P(120<m<=180) = 13/40

P(180<m<=240) = 7/40

P(240<m<=300) = 6/40

Probability that it has a mass of more than 120 g = [P(120<m<=180) + P(180<m<=240) + P(240<m<=300) ]

The number of  mozzarella sticks that will be in the larger sample will be 5.

Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s). The sign used to express ratios is :.

The first step is to determine the ratio of mozzarella sticks to pretzel bites in the smaller sample. This can be done by dividing the quantity of  mozzarella sticks by the number of pretzel bites.

Number of mozzarella sticks / number of pretzel bites = 2 : 8  or 1 : 4.

Answer:

Neither is correct

Step-by-step explanation:

Look at each side of the smaller figure and compare it to the larger figure. That will give you the scale: (Larger figure length)/(Smaller figure length)

Let's take the base
Smaller figure is 6 units
Larger figure is 9 units

Scale = 9/6 = 1.5

Take the vertical height
Smaller figure = 4

Larger figure = 8
So here the scale is 2

Scaling is inconsistent for different sides of the figure

So neither of them is right. For a figure to be scaled, all its sides must be scaled by the same number

Answer:

No solution

Step-by-step explanation:

First I plugged the value of y into the equation 10x-2y=, which gave me
10x- 2(5x - 3) = 7. Then you can distribute the -2 into the parenthesis giving you 10x - 2(5x)(-2 x -3) = 7. This leaves us with 10x- 10x + 6 = 7, because two negatives multiplied together form a positive. Now you subtract six from both sides to keep it equal, and you're left with 10x-10x= 1. This gives you 0= 1, which is not possible, so there is no solution.

We can check our work by putting 10x -2y= 7 into y=mx+b format, by subtracting 10x from both sides, leaving you with -2y = -10x+ 7. then you can divide out the -2, giving you y= 5x+ 7/5. Notice how the slopes in both our equations are 5x. This means that they are a group of parallel lines, bc they both stay at the same rate, despite having different y-intercepts or starting points.
