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

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.

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

Mr. Duncan earns 75$ a day plus 35$ for each car he sells. if c is his total earnings and x is the number of cars he sold, what is the equation
Answers
Answer: c= 35x + 75
Step-by-step explanation:
If he earns $75 then that will be the constant amount which means it will never change, plus $35 for x cars, will give us the expression 35x + 75 and that has to equal c which is his total earnings.
Answer:
c = 35x + 75Step-by-step explanation:

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

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).

On a family road trip, Mr. Edwards travels 130 miles in two hours. At this rate, how many miles will he travel in 30 minutes? (watch the time on this one!) Group of answer choices
Answers
Answer:
32.5 miles in 30 minutes.
Step-by-step explanation:
There are a total of 4 - 30 minute segments in a period of two hours. Therefore, in this question, we can simply divide the total distance that Mr Edwards travelled during those two hours by the 4 segments, and that would give us the distance travelled in a single segment of 30-minutes.
130 / 4 = 32.5 miles
Finally, we can see that Mr Edwards travelled 32.5 miles in 30 minutes.
