Answer:

8 x - 1

Step-by-step explanation:

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

(HOW DO YOU SOLVE EQIVALENT EXPRESSIONS)

Answer:

8x-1

Step-by-step explanation:

3x+5x=8x

8x-1

You add up the numbers that have the same variables, then add the extra numbers to numbers you solved.

Answer:

4 (3 y + 2 x)^2

Step-by-step explanation:

Factor the following:

36 y^2 + 48 x y + 16 x^2

Hint: | Factor out the greatest common divisor of the coefficients of 36 y^2 + 48 x y + 16 x^2.

Factor 4 out of 36 y^2 + 48 x y + 16 x^2:

4 (9 y^2 + 12 x y + 4 x^2)

Hint: | Factor by grouping.

The coefficient of x^2 is 4 and the coefficient of y^2 is 9. The product of 4 and 9 is 36. The factors of 36 which sum to 12 are 6 and 6. So 9 y^2 + 12 x y + 4 x^2 = 4 x^2 + 6 x y + 6 x y + 9 y^2 = 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 2 x (3 y + 2 x) + 3 y (3 y + 2 x)

Hint: | Factor common terms from 2 x (3 y + 2 x) + 3 y (3 y + 2 x).

Factor 3 y + 2 x from 2 x (3 y + 2 x) + 3 y (3 y + 2 x):

4 (3 y + 2 x) (3 y + 2 x)

Hint: | Combine products of like terms.

(3 y + 2 x) (3 y + 2 x) = (3 y + 2 x)^2:

Answer: 4 (3 y + 2 x)^2

The word "times" means you have to multiply.

2 1/5 times 1 3/4 is 3 17/20.

The phrase "how many more" means you have to subtract.

3 17/20 minus 2 1/5 is 1 13/20.

Answer:

200 I think I'm not entirely sure

Answer:

200

Step-by-step explanation:

if one inch=40 miles, and we want to find 5 inches, we can solve 5*40, which equals 200

i need the equation from the first question

Step-by-step explanation:

$21

Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x

If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21

Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21

Answer:

235or 236

Step-by-step explanation:

A cone has a radius of 5 cm

a height of 9 cm

Volume of cone =1/3πr^2h

=1/3×3.14×5×5×9

= 3.14×25×3

=3.14×75

=235.5

=235or 236 is the answer

Answer:

Week 1: 14

Week 2: 18

Week 3: 2

Week 4: 9

Week 5: 23

Week 6: 6

Step-by-step explanation:

The question is asking for the percentage of absences each week given the percentage of attendance. We can calculate [tex]100\%-Attendance[/tex] (attendance is in percentage form) to find the percentage of people that were absent during each get-together:

Week 1: [tex]100\%-86\%=14\%\\[/tex]

Week 2: [tex]100\%-82\%=18\%[/tex]

Week 3: [tex]100\%-98\%=2\%[/tex]

Week 4: [tex]100\%-91\% = 9\%[/tex]

Week 5: [tex]100\%-77\% = 23\%[/tex]

Week 6: [tex]100\%-94\% = 6\%[/tex]

2(3) + (3) = 9

3(3) - 2(3) = 3

Answer:

x= -2 y= -1

Step-by-step explanation:

stack the 2 equations on top of each other and add them together

the 2x and -2x cancel out and you are left with -9y=9

this gives you y= -1

you plug the y value into one of the equations:

2x - (-1) = -3

2x+1 = -3

2x= -4

x= -2

Answer:

The length of the rectangle is 17 yards and the width of the rectangle is 14 yards.

Explanation:

To find the perimeter of the rectangle, you had to add twice the length of the rectangle to twice the width of the rectangle since the shape of a rectangle is made up of two legs (each representing the rectangle's length) and two legs (each representing the rectangle's width.

The perimeter can be mathematically seen as p = 2l+2w, where p is the amount corresponding to the perimeter of the rectangle, l is the amount representing the length of the rectangle, and w is the quantity reflecting the width of the rectangle. This equation can be modified using the equation l = w+3, since it is given that the length is 3 yards longer than the width.

Therefore, the p = 2l+2w equation can be modified to solve for w using the given conditions and the equation defining l.

p = 2l+2w  

p = 2(w+3)+2w               [Substituting l = w+3]

p = 2w+6+2w

p = 4w+6

p-6 = 4w+6-6

p-6 = 4w

(p-6)/4 = 4w/4

w = (p-6)/4

w = (62-6)/4                  

w = 56/4

w = 14

Now the length of the rectangle can be determined using the equation l = w+3.

l = 14+3 = 17

We need to determine the equation of both lines first.

Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.

Line 1:

[tex]y = -2x + 3\\\\2x + y = 3[/tex]

Line 2:

[tex]y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2[/tex]

Final answer:

[tex]2x + y = 3\\\frac{1}{3}x + y = -2[/tex]
