Answer:

y=2x-4

Step-by-step explanation:

so we just have to rearrange this to

2y=4x-8

we can do this by adding 4x to both sides

then we divide by 2

y=2x-4

Kerry is comparing the fuel efficiency of two cars, Car A and Car B. Car A lists gas mileage as 32.4 miles per gallon for highwa

andrezito [222]

Okay. To find the miles per gallon of B, we have to divide 100 by 2.6. 100/2.6 is 38.4615385 or about 38.5 miles per gallon when rounded to the nearest tenth. Car B goes approx. 38.5 miles per gallon.

Solve for m pls? I'd seriously appreciate it!

Vilka [71]

Answer:

$m=-1$

Step-by-step explanation:

Start by multiplying both sides by 2, this will get rid of the fraction on the left side and will result in the equation $12m+6=2m-4$

Then, subtract 2m from both sides, which leaves the equation as $10m+6=-4$

Then, subtract 6 from both sides, this results with the equation $10m=-10$

Finally, divide both sides by 10, this will result in m=-1

Bamboo Plant A is 1.2 meters tall and growing at a rate of 0.45 meter per day. Bamboo Plant B is 0.85 meter tall and growing 0.5

pashok25 [27]

Answer:

7 days

Step-by-step explanation:

Bamboo plant A = 1.2 + 0.45d

Bamboo plant B = 0.85 + 0.5d

Where,

d = number of days

Equate the two growth

Bamboo plant A = Bamboo plant B

1.2 + 0.45d = 0.85 + 0.5d

Collect like terms

1.2 - 0.85 = 0.5d - 0.45d

0.35 = 0.05d

Divide both sides by 0.05

d = 0.35 / 0.05

d = 7 days

Plant B be taller than Plant A after 7 days

Awnser and show your work <3

marishachu [46]

Answer:

Team A: 25 players

Team B: 24 players

Step-by-step explanation:

Team A:

to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:

$\frac{5}{x} = \frac{1}{5}$

then we cross multiply to get

x*1 = 5*5

x=25 players

Team B

similarly to Team A

$\frac{3}{x} = \frac{1}{8}$

cross multiply to get

x*1=3*8

x= 24 players
