Answer:

Jonathan gets more time playing video games.

Step-by-step explanation:

Consider the provided information.

His friend Lucas's parents told their son that he could play 30 minutes for every hour of homework or reading time he completes.

For each hour Lucas can play 30 minutes.

This can be written as:

1 Hour study = 30 minutes of play

Jonathan's parents told him that for every 5 hours of homework or reading he completes,he would be able to play 3 hours of video games.

This can be written as:

5 Hour study = 3 hours of play

Convert hours into minutes

5 Hour study = 3×60 minutes of play

5 Hour study = 180 minutes of play

Divide both side by 5.

1 Hour study = 180/5 minutes of play

1 Hour study = 36 minutes of play

Lucas can play 30 minutes for every hour of homework while Jonathan can play 36 minutes for every hour of homework.

Hence, Jonathan gets more time playing video games.

Which system of equations is incondsistent? a. 2x+8y=6 5x+20y=2
galina1969 [7]

Answer: Yes

Step-by-step explanation:

2x+8y=6

-8y -8y

2x = -2y

Divide by two so x will be by itself, so the answer will be -1y.

5x+20y=2

-20y -20y

5x = -18y

Divide by 5 so x will be by itself, so the answer will be -3y.

Ray has found that his new car gets 31 miles per gallon on the highwayand 26 miles per gallon in the city. He recently drove 285
Mkey [24]

Answer:

Highway = 155\ miles

City = 130\ miles

Step-by-step explanation:

Given

Highway = 31mi/gallon

City = 26mi/gallon

Total\ Miles = 285

Total\ Gallons = 10

Required

Determine the number of miles driven on the highway and on the city

Represent the gallons used on highway with h and on city with c.

So, we have:

c + h = 10 ---- gallons used

and

31h + 26c = 285 --- distance travelled

In the first equation, make c the subject

c = 10 - h

Substitute 10 - h for c in the second equation

31h + 26c = 285

31h + 26(10 - h) = 285

Open bracket

31h + 260 - 26h = 285

Collect like terms

31h - 26h = 285 - 260

5h = 25

Make h the subject

h = \frac{25}{5}

h = 5

Substitute 5 for h in c = 10 - h

c = 10 - 5

c = 5

If on the highway, he travels 31 miles per gallon, then his distance on the highway is:

Highway = 31 * 5

Highway = 155\ miles

If in the highway, he travels 26 miles per gallon, then his distance on the highway is:

City = 26 * 5

City = 130\ miles

Consider the first 2 terms of the sequence -6, 18,...
____ [38]

Answer:

arithmetic sequence: 24, 42, 66, 90, 114; y = 24x - 30

geometric sequence: -54, 162, -486, 1458, -4374; y = -6(-3)^(x - 1)

Step-by-step explanation:

Arithmetic sequence:

-6, 18, ...

18 - (-6) = 24

18 + 24 = 42

42 + 24 = 66

66 + 24 = 90

90 + 24 = 114

y = -6 + 24(x - 1)

y = -6 + 24x - 24

y = 24x - 30

Geometric sequence:

-6, 18, ...

18/(-6) = -3

18 * (-3) = -54

-54 * (-3) = 162

162 * (-3) = -486

-486 * (-3) = 1458

1458 * (-3) = -4374

y = -6(-3)^(x - 1)
