The lines p and q intersect at point O. What is the value of x? Enter your answer in the box. x = Lines p and q intersect at point O. Acute vertical angles measure two x plus thirteen degrees, and three x minus three degrees.

Answers

Answer:

x = 16

Step-by-step explanation

Find the diagram attached. You can see from the diagram that both angles are vertically opposite angles and vertically opposite angles are equal.

Hence 2x+13 = 3x-3

Collect like terms

2x-3x = -3-13

-x = -16

Multiply both sides by -1

-1(-x) = -1(-16)

x = 16

Hence the value of x is 16

Answer:

x=16 hope this helps!

Step-by-step explanation:

The expression that represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a² + 25).

What is the distance between two points of a line?

The distance between two points of a line is given as:

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

We have,

The distance formula can be used to find the distance between two points on a coordinate grid.

The distance between the points (a, 0) and (0, 5) is given by:

√((a - 0)² + (0 - 5)²)

Simplifying the expression gives:

√(a² + 25)

Thus,

The expression that represents the distance between the points (a, 0) and (0, 5) on a coordinate grid is √(a² + 25).

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?

Answers

Answer:

1 hour 42 minutes approx

Step-by-step explanation:

Given data

Mayas work rate= 1/4 room per hour

Reginald work rate= 1/3 room per hour

Let the total time taken for both of them be T

Hence their combined work rate

1/4+1/3= 1/T

3+4/12=1/T

7/12=1/T

T= 12/7

T= 1.7 hours

Hence it will take them 1 hour 42 minutes approx

Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?

Answers

Answer:

Cereal A is cheaper by $0.15

Step-by-step explanation:

Cost of a 10-ounce box of Cereal A = $2.70

So,

Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]

Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]

Also,

Cost of a 13-ounce box of Cereal B = $3.64

So,

Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]

Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]

Here,

Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]

Therefore,

Cereal A is cheaper by $0.15
