B jada writes this equation for the sum of the ages (x)+(x+3) +3(x+3)-1=87 explain the meaning of the variable and each term of the equation.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex](x)+(x+3) +3(x+3)-1=87[/tex]

simplifying the equation

[tex]x+x+3+3x+9-1=87[/tex]

adding similar elements

[tex](x+x+3x)+(3+9-1-87)=0[/tex]

[tex]5x-76=0[/tex]

Thus, the equation is a linear equation in one variable 'x'.

A term is a single mathematical expression, so the simplified expression has two terms which are:

5x-76

The term 5x has the variable 'x' of power 1.

The term -76 does not involve any variable, Hence, -76 is a constant term.

Graph the line with slope
1/2 and y-intercept -9

Answers

Answer:

Step-by-step explanation:

slope is the x axis and y intercept is the y axis

so 1/2 will go on the x axis and -9 will go on the y axis

1/2 uses the rise over run method

Answer:

Answer is in the screenshot. The equation for the line is y=1/2 x - 9

Step-by-step explanation:

To graph a line when you know the slope and y intercept, you make a point on the y intercept. Your y intercept iIs -9 so you would make a point on (0,-9).

After you have the point on (0,-9) you use the slope to create the rest of your line. Slope is just Rise  

                            Run

Your slope is 1/2. That means your next point on the line is up 1 unit and right 2 units. The next point on the line is (2,-8).

Nicholas has 22 nickels, dimes, and quarters. There are 3
less dimes than quarters and 2 more dimes than nickels.
How much money does he have?

Answers

Nickels: 22

Dimes: 24

Quarters: 27

2 more dimes than nickels, we already know that there are 22 nickles so...

Dimes= 24

3 less dimes that quarters ^(we already know how many dimes).

All we have to do is add 3 to the amount of dimes!

Quarters 27

____________________________________________________________

Now to find the amount of money you have to find out what each coin equals and multiply the number of coins by the cost of each coin, and then by 100 because there are 100 cents in 1 dollar.

22 nickels*5/100= $1.10

24 dimes*10/100= $2.40

27 quarters*25/100= $6.75

1.10+2.40+6.75= $10.25

The amount of money he has in $10.25

N more then then the difference of 7 and 2

If the sides to a triangle are 20, 40, and 80 cem, is it Right triangle?

Answers

Answer: no

because using Pytago theorem, we have:

20² + 40² ≠ 80²

80² + 20² ≠ 40²

80² + 40 ² ≠ 20²

Step-by-step explanation:

Answer:

No, it does not follow the Pythagorean Theorem.

Step-by-step explanation:

A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.

the square root of 2000 equals about 44.7213595.

Thus, a triangle with sides 20, 40, and 80 is not a right triangle.

In a scale drawing of a house, 2 inches : 5 feet. The actual kitchen of the house will be 17 feet long. How long will the drawing of the kitchen be?

A. 5.2

B. 6.8

C. 7.5

D. 8

Answers

Answer:

B, 6.8

Step-by-step explanation:

Let's first find how many feet it is per 1 inch. We can do this by dividing 5 by 2

5/2= 2.5

Now it is 1 inch : 2.5 feet

17/2.5 = 6.8

1 x 6.8 = 6.8

6.8 inches : 17 feet

You could also solve this by doing

17/5 =3.4

3.4 x 2 = 6.8

6.8 inches : 17 feet
