Answer:
x = -4
Step-by-step explanation:
2(x-8)=x+5x
Combine like terms
2(x-8) = 6x
Divide by 2
2(x-8)/2 = 6x/2
x-8 = 3x
Subtract x from each side
x-8-x = 3x-x
-8 = 2x
Divide by 2
-8/2 = 2x/2
-4 =x

You’d like to see how many baseball and soccer games you can attend this spring. Travel time for basketball games is 2 hours and soccer games is 1 hour. You would like to spend no more than 15 hours traveling to the games. In total, you would like to attend at least 8 games.
We have to attend 7 basketball games and 1 soccer game.
Given, we had two types of game namely basketball and soccer.
Travel time for basketball games is 2 hours and soccer games is 1 hour.
Let no. of basketball games be x and no of soccer games be y.
According to the question we would like to attend at least 8 games, so we have the inequality [tex]x+y\geq 8[/tex]
And we would spend no more than 15 hours traveling to the game, so [tex]2x+1y\leq 15[/tex].
[tex]x+y=8\\[/tex]
[tex]2x+1y=15\\[/tex]
On solving we get [tex]x=7[/tex] and [tex]y= 1[/tex].
Hence we have to attend 7 basketball games and 1 soccer game.

A.6 s
B.7 s
C.19 s

Step-by-step explanation:
not A or d
B or C
All I did was divide 95 and 5 and I got 19!
hope this helps!:)
Answer:
B.) 7 seconds
Step-by-step explanation:
We are given that the ant can crawl 95 centimeters in 5 seconds, which means that it can crawl 19 centimeters in 1 second (95 centimeters/5 seconds). Now you need to divide 19 from 133 (133 centimeters/19 centimeters per second), and you get 7 seconds.
A student has passed 60 percent of the 20 quizzes he has written so far successfully. If the student writes 50 quizzes during the year, and passes 80 percent of the remaining quizzes successfully, what would his average percentile be?
Answer:
A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:
successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12
The remaining quizzes = 50 - 20 = 30 quizzes
80 percent of the remaining quizzes successfully mean:
The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24
Total successfully quizzes = 12 + 24 = 36
Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %
Pls rate Brainliest!
Answer:73%
Step-by-step explanation:A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:
successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12
The remaining quizzes = 50 - 20 = 30 quizzes
80 percent of the remaining quizzes successfully mean:
The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24
Total successfully quizzes = 12 + 24 = 36
Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %

The answer is 55. You need to use the rules above to find the actual measure for angle b
Step-by-step explanation:
A circle is 360 degrees
209 is part of the circle so find the difference between 360 and 209
360 - 209 = 151
If the two angles are equivalent to 151, then we find the difference between 151 and 96 to get the measurement for angle b
151 - 96 = 55
I read now that it says use the rules above, but I'm not seeing any rules in the picture so hopefully my steps are the rules you're referring to

A drone costs $200, and you receive a 15% discount due a coupon. What is
the total amount to be paid?
Answer:
the total would be 170 dollars
Step-by-step explanation:
200x0.15
Answer:
$170
Step-by-step explanation:
15% of 200 is 30, so subtracting 30 from 200 gets you 170.
If you're having trouble with finding 15% of 200, just flip it around, and find 200% of 15. 15% of 200 and 200% of 15 are both 30. This works no matter what numbers you have. For example, 8% of 100 and 100% of 8 are equivalent, 70% of 200 and 200 and 200% of 70 are equivalent as well.

40/100 = 140/x Cross multiply
40x = 100* 140 Combine the right
40x = 14000 Divide by 40
x = 14000/40
x = 350
She took 350 shots in total.
In a city the distance between the libary and the police station is 3 miles less than than the distance between the police station and fire station the distance between the libary and police station is 5 miles how far apart are the police station and the fire station
Answer:
8 miles
Step-by-step explanation:
Given
Represent the police station with P, Library with L; Fire station with F
The first statement can be represented as:
[tex]L - P = P - F - 3[/tex]
The second can be represented as:
[tex]L - P = 5[/tex]
Required
Determine the distance between the police station and the fire station (P - F)
[tex]L - P = P - F - 3[/tex] --- (1)
[tex]L - P = 5[/tex] --- (2)
Substitute 5 for L - P in (1)
[tex]5 = P - F - 3[/tex]
Add 3 to both sides
[tex]3 +5 = P - F - 3 + 3[/tex]
[tex]3 +5 = P - F[/tex]
[tex]8= P - F[/tex]
[tex]P - F = 8[/tex]

Leigh is renting a moving van The function C (d) = 0.12d + 25 is used to relate the cost, C, in dollars of the rental after Leigh
uses the van for d miles. What is the interpretation of the slope for this function? (1 point)
The initial cost of the moving van is $0.12
The additional cost is $25 for each additional mile the van is driven
The initial cost of the moving van is $25.
The additional cost is $0.12 for each additional mile the van is driven
Answer:
The additional cost is $0.12 for each additional mile the van is driven ⇒ D
Step-by-step explanation:
The form of the linear function is
f(x) = m x + b, where
m is the rate
b is the initial value
In our question
The function C(d) = 0.12 d + 25 represents the cost C in dollars of the rental van uses for d miles
→ Compare it with the form of the linear function above
∴ m = 0.12
∴ b = 25
∵ The cost C depends on the number of miles d
∴ $0.12 is the cost per mile ⇒ additional cost for each additional mile
∴ $25 is the initial cost ⇒ initial cost of the moving the van
The interpretation of the slope for this function is:
The additional cost is $0.12 for each additional mile the van is driven
Answer:
+0.12
Step-by-step explanation:
The additional cost is 0.12 cents for each additional mile the van is being driven.
