Answer:

8 Bags

Step-by-step explanation:

If two bags cost $5, and you can spend $20, the amount of money multiplies by 4, so the number of bags would also.

2 x 4 = 8

Answer:

2x=1

Step-by-step explanation:

Use x for "a number"

x times 2 = 1

2x=1

which solves for 0.5 or 1/2

2x = 1

Step-by-step explanation:

hello! here is your answer

Answer:

1) ∠2 ≅ ∠7

⇒ they are corresponding angles

2) ∠5 ≅ ∠9

⇒ they are alternate interior angles

3) ∠4 ≅ ∠7

⇒ they are vertically opposite angles

4) if ∠3 ≅ ∠8, then p║q

⇒ they are corresponding angles

5) ∠3 ≅ ∠9

⇒ they are vertically opposite angles

6) m∠2 + m∠3 = 180

⇒ they are co-interior angles

7) ∠4 is vertical to ∠7

8) ∠2 and∠3 are same side interior angles

9) ∠5 corresponds to ∠8

10) one alternate exterior pair is ∠1 and ∠8

hope it helps you!!

Answer:

Step-by-step explanation:

Use the slope formula:

[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]

where m = slope

(-5, 0) -> means x1 = -5. y1 = 0

(7, 8) -> means x2 = 7 , y2 = 8

Substitute these values into the slope formula above and you get:

[tex]m = \frac{y2 -y1}{x2 - x1} = \frac{8-0}{7- (-5)} = \frac{8}{7+5} = \frac{8}{12} = \frac{2}{3}[/tex]

The slope of the line that passes through the points (-5,0) and (7,8) is 2/3

The formula for calculating the slope of a line is expressed as:

[tex]m = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{8-0}{7-(-5)} \\m=\frac{8}{7+5}\\m=\frac{8}12} \\m= \frac{2}{3}\\[/tex]

Hence the slope of the line that passes through the points (-5,0) and (7,8) is 2/3

Answer:

x=−3 and y=−1

Step-by-step explanation:

Substitute y=4x+11y=4x+11 into 2x-5y=-12x−5y=−1

-18x-55=-1−18x−55=−1

Solve for x in -18x-55=-1−18x−55=−1.

x=-3

Substitute x=-3x=−3 into y=4x+11y=4x+11.

y=-1

Answer:

28

Step-by-step explanation:

2x-5(4x+11)=-1

2x-20x+55=-1

-22x+55=-1

-22x+55-55=-1-55

-22x/-22=-56/-22

x=28

The x coordinates, 6 and 6, add to 6+6 = 12. Then we cut this in half getting 12/2 = 6.

The x coordinate of the midpoint is 6.

The y coordinates, 7 and -5, add to 7+(-5) = 2. Which cuts in half to get 2/2 = 1.

The y coordinate of the midpoint is 1.

Put together, the midpoint is located at (6,1)

Step-by-step explanation:

Answer:

y = 2x + 3

Step-by-step explanation:

Parallel lines must have the same slope, in the given equation, the slope is 2, so the slope for the parallel line must also be 2, so that eliminates answer choices B and D.

Now to choose between answer choices A or C, you can just plot the given point (-3, -3) into each equation and see which one fits. Answer A seems to be the correct answer.

Answer:

k = 3

Step-by-step explanation:

8k - (6k - 4) = 10

8k - 6k + 4 = 10

2k + 4 = 10

2k = 10 - 4

2k = 6

k = 3

Answer:

k=3

Step-by-step explanation:

8k-(6k-4)=10

Multiply everything inside of the parentheses by the negative.

8k -6k -4=10

Combine like terms

2k - 4 = 10

Subtract 4 from both sides

2k = 6

Divide by 2 on both sides
