What is the value of (6a-2)

Answers

Answer 1

Answer: It totally depends on the value of 'a', and if 'a' changes, then (6a-2) immediately changes too. Whatever 'a' is at the moment, (6a-2) is 2 less than 6 times 'a'.

i made a clay snake 9 5/8 inches long, but a section 1 7/8 inches long broke off. how longis the snake now?

Answers

The answer is 7 3/4.
Turn into improper fraction
= 77/8 − 15/8

= ((77 × 8) − (15 × 8)) / (8 × 8)

= (616 - 120) / 64

= 496/64

= 31/4

First, I would convert it an improper fraction.9 5/8 = 77/81 7/8 = 15/877 - 15 = 62. The denominator stays the same.62/8. Divide to make it a mixed number.62/8 = 7 6/8Simplified to = 7 3/4

The quantities x and y are proportional. If x is 3 and y is 9, find the constant of proportionality (r) in the equation y = rx. A) 1 B) 2 C) 3 D) 4

Answers

Answer:

Step-by-step explanation:

given that x and y are proportional then the equation relating them is

y = rx ← r is the constant of proportionality

to find r, substitute x = 3 and y = 9 into the equation

9 = 3r ( divide both sides by 3 )

3 = r

the constant of proportionality is r = 3

On Friday, Kelsey went to a local carnival. She bought a pretzel for $5 and played three games. On Saturday, Kelsey went back to the carnival and bought an ear of corn for $3 and played five games. If all the games cost the same amount to play, and Kelsey spent the same amount of money each day, how much does each game cost to play?A $1.00
B $1.25
C $1.50
D $2.00

Answers

set the question up as an equation, where x is equal to the cost of a game
FRIDAY: 5+3x
SATURDAY: 3+5x

∴ 5+3x=3+5x
2=2x
x=1
Therefore the cost of 1 game is $1

The best answer is A since each game cost the same amount and she spent the same amount both days, u can just add the number of games for the first day which is 3 with $5 and get $8.and for the second day just add $3 with $5 and u get $8 again.

Answers

Part 1: Keisha ran to swim practice but needed to stop by her friend Natasha’s house on the way. She stayed at Natasha’s house for 15 minutes, and together they ran the rest of the way to practice, where they stayed for 1 hour.

If we graph this there will be 3 segments because the slope of each segment is Keisha's speed during that interval:

⇒ The middle segment will have no slope,which makes the slope undefined.

⇒ The 1st and 3rd segments will have positive slopes, If a line has a positive slope, variable y always increases when x increases.

Choice A). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 5, decreases to 0.25 comma 2, stays horizontal to 0.6 comma 2, then increases to 0.75 comma 9. The line is horizontal to 1.75 comma 9.

The given graph started that the time is 0, when Keisha begins
running. she is already 5 blocks from home. So this data is incorrect. The graph also states that the line decreases,when she runs toward her home.

Terrible choice.

Choice B). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 0.3 comma 2, increases to 0.5 comma 5, then increases to 0.75 comma 9. The line decreases to 1.75 comma 0, where it touches the axis.

Terrible choice.

Choice C). This is the correct answer. It includes all the information that appears on the given graph, and it matches the given story.

Choice D). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 5, is horizontal to 0.3 comma 5, increases to 0.5 comma 6, is horizontal to 0.8 comma 6, then increases to 1.75 comma 9

Terrible choice.

Part 2 : Sasha withdrew spending money. Meaning : To remove (money) from an account.

The correct answer is the last one.

Q1:
Answer:
A coordinate plane graph is shown. The x-axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 0.25 comma 5, stays horizontal until 0.5 comma 5, then increases to 0.75 comma 9. The line is horizontal until 1.75 comma 9.

Explanation:
First segment: distance and time increases (Keisha ran to Natasha's house)
Second segment: time increases, distance is constans (Keisha stayed at Natasha’s house)
Third segment: distance and time increases (Keisha and Natasha ran to swim practice)
Fourth segment: distance is constans, time increases (Keisha and Natasha stayed on practice).

Q2.
Answer:
Sasha did not withdraw or deposit any money. (During 5 days of the account balance has not changed).
