11 Alicia buys a car that costs $26610, and she makes a $3140 down payment on it. How much
does she still owe on the car? Give units.

Answers

Answer:

$23,470

Step-by-step explanation:

A down payment is how much you pay upfront for a car. So, how much she still owes will be the difference between the total cost and the down payment. Therefore, subtract $3,140 from $26,610; 26610-3140=23470. Then, since you are talking about money the units are dollars, $.

Find the slope of the line passing through the points (-5, 3) and (7, 9)

For any two points (a,b) and (c,d) ,

Step-by-step explanation:

Determine whether the following statement is true or false.
A proper use of units can help us to determine the meaning of the slope of a linear function.

Answers

The correct answer would be true

Here we want to see if the statement:

"A proper use of units can help us to determine the meaning of the slope of a linear function" is true or false.

We will see that it is true.

First, a general linear equation can be written as:

y = a*x + b

Where a is the slope, x is the independent variable, y is the dependent variable, and b is the y-intercept.

The proper use of units is:

y and b must have the same units.

x can have any type of units

The slope must have the quotient between the units of y and the units of x.

Where the proper use of units means that we have the same units on both sides of the expression.

Now, assume that we know the units of y and x.

For example:

y is miles  (then b is also in miles)

x is in hours

Then, with the proper use of units, we can see that the units of the slope are:

miles/hour, or miles per hour.

With this (only knowing the units of x and y) we can see that the slope will be a speed.

So yes, the proper use of units is really important, as this has a lot of information (particularly, the meaning of the slope in a linear equation)

Thus, the statement is true.

the unit rate of 1/7 is itself (1/7), and for 1/21 is 1/21.

this is because these rates/ratios are unit fractions. so if the numerater is 1, theres nothing you can do to simplify it.

Margie had 4 2/5 pans of lasagna. After a party she has 1 1/2 pans left. How much lasagna was eaten at the party

Answers

Answer:

2 9/10 pans

Step-by-step explanation:

4 2/5-1 1/2=2 9/10 pans

2 and 9/10 pans of lasagna were eaten at the party.

To find out how much lasagna was eaten at the party, you need to calculate the difference between the initial amount of lasagna Margie had and the amount she has left after the party.

Initial amount of lasagna = 4 2/5 pans

Amount left after the party = 1 1/2 pans

First, we need to convert both fractions to a common denominator. The common denominator of 5 and 2 is 10.

Initial amount of lasagna = 4 x 10/10 + 2/5 x 10/10

= 40/10 + 4/10

= 44/10 pans

Amount left after the party = 1 x 10/10 + 1/2 x 10/10

= 10/10 + 5/10

= 15/10 pans

Now, subtract the amount left after the party from the initial amount to find out how much lasagna was eaten:

Amount eaten = Initial amount - Amount left

Amount eaten = 44/10 - 15/10 = 29/10 pans

You can simplify the fraction further:

Amount eaten = 2 + 9/10 pans

So, 2 and 9/10 pans of lasagna were eaten at the party.

X/2-7=9

Show your work in details if you can, I have a hard time understanding this.

Answers

I’m not very good at math but here’s my reasoning:
x/2-7=9
I moved the 7 to the other side of the equation
So now
X/2 = 9 + 7
X/2 = 16
Since x is equal 16 if you divide x by 2 (because x/2=16), that means if you want to find x you need to multiply x by 2
X = 16 x 2
X = 32
I hope it’s right !! <3

Answer:

Step-by-step explanation:

x/2  - 7 = 9                  Add 7 to both sides

      +7     7

x/2 = 16                        Multiply both sides by 2

2*x/2 = 16*2        

x = 32

You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.

Take a much simpler question

x - 8 = 10        What do you do here? You can't multiply or divide. So add

  +8    8

x    =    18

Now try what you have

2x - 5 = 11                      Add before multiplication or division

    5      5

2x = 16                          Divide by 2

2x/2 = 16/2

x = 8

45 and 5 are the dimensions of the block of land.​

Step-by-step explanation:

2(x + y) = 100, x + y = 100/2, y = (50 - x)

xy = 225

x (50 — x) = 225

0 = x^2 — 50x + 225

0 = (x — 45) (x -5)

Answer:

3x – y = -6

Step-by-step explanation:

To solve on the problem above, you can do it by substitution and elimination of the two equations.

3x + 2y = 3

➡️ 3x + 2.3 = 3

➡️ 3x + 6 = 3

➡️ 3x = -3

➡️ x = -1

➡️ 3x – y = 3(-1) – 3
