General Formulas and Concepts:

Pre-Alg

Equality Properties

Geometry

Congruent AnglesAll angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Define

m∠D = 58°

m∠E = m∠F = x

Step 2: Set up equation

58 + x + x = 180

Step 3: Solve for x

Combine like terms:                    58 + 2x = 180Subtract 58 on both sides:          2x = 122Divide 2 on both sides:               x = 61°

Step 4: Find angle measures

Define:          m∠E = x°Substitute:    m∠E = 61°Define:          m∠F = x°Substitute:    m∠F = 61°

What is the value of x?

Answers

Answer:

x = 8

Step-by-step explanation:

recall that all internal angles of a triangle sum up to 180 deg

we are given that ∠F is a right angle = 90 deg

Simply sum all all the angles and equate the sum to 180 deg

90 + (3x+29) + (5x-3) = 180

90 + 3x+29 + 5x-3 = 180

90 + 3x+29 + 5x-3 = 180

116 + 8x = 180  (subtract 116 from both sides)

8x = 180 - 116

8x = 64  (divide both sides by 8)

x = 64/8

x = 8

I believe it is 8 since the three angles must add up to 180°

Jimmy purchased 15 tickets to a concert and spent $140. He purchased some children's tickets and some adult tickets. The children's tickets cost $7 each and the adult tickets cost $12 each. Write a system that represents this situation. How many of each did Jimmy purchase?​

Answers

Answer:

Jimmy purchased 8 of the children's ticket and 7 of the adult's ticket.

Step-by-step explanation:

Let c = children tickets

Let a = adult tickets

Given the following data;

Number of tickets = 15

Total amount spent = $140

Cost of each children ticket = $7

Cost of each adult ticket = $12

*Translating the word problem into an algebraic equation (system)*

For the total number of tickets;

[tex] c + a = 15 [/tex] .........equation 1

For the total amount spent;

[tex] 7c + 12a = 140[/tex] ..........equation 2

*Solving the linear equation by using the substitution method*

Making c the subject in equation 1:

[tex] c = 15 - a[/tex] .......equation 3

Substituting "c" into equation 2;

[tex] 7(15 - a) + 12a = 140 [/tex]

Simplifying the equation, we have;

[tex] 105 - 7a +12a = 140[/tex]

[tex] 105 + 5a = 140[/tex]

Rearranging the equation, we have;

[tex] 5a = 140 - 105[/tex]

[tex] 5a = 35[/tex]

[tex] a = \frac {35}{5} [/tex]

a = 5 (For the $12 adult ticket).

To find the number of children tickets;

Substituting "a" into equation 3;

[tex] c = 15 - 7[/tex]

c = 8 (For the $7 children ticket).

Leon drove from his house in Cincinnati to his sister’s house in Cleveland, a distance of 252 miles. It took him 4.5 hours. For the first half-hour, he had heavy traffic, and the rest of the time his speed was five miles per hour less than twice his speed in heavy traffic. What was his speed in heavy traffic?

Answers

Answer:

Speed in heavy traffic is 32 miles per hour

Step-by-step explanation:

Total distance = 252miles

Total time = 4.5hours = 4 hours + 30minutes

Let the speed in heavy traffic = x

distance = time * speed

First half hour    

D1 = 0.5*x

The speed after the traffic = 2x - 5

D2= 4* (2x - 5)  

Total distance = D1 + D2

    [tex]\frac{x}{2}[/tex]  + 8x - 20 = 252

        [tex]\frac{17x}{2}[/tex]   = 272

      x = [tex]\frac{272}{17}*2[/tex]

      x = 32 miles per hour

Ashley found 2 boxes of sugar in the kitchen. The green box is 1.26 kg and the red box is 1.026 kg. Which box contains more sugar?

Answers

Answer:

Answer:

Green box contains more sugar.

Step-by-step explanation:

Consider the provided information.

Ashley found 2 boxes of sugar in the kitchen.

The green box says 1.26 kg and the red box says 1.026 kg.

we need to find which box contains more sugar.

To find this we will first check the digit at ones place.

Both the digit has 1 at the ones place. So now check the digit at tenths place.

1.26 has 2 at tenths place while 1.026 has 0 at tenths place.

As we know 2 is greater than 0, thus the number 1.26 is greater than 1.026.

Hence, green box contains more sugar.

The green box has more sugar because if you convert it to pounds the red box has 2.26 pounds of sugar while the green box has 2.777825 pounds.
