Answer:

The answer is 215=55x+40 or 215=40+55x

Step-by-step explanation:

The reason it is that is because the plumber charges $55 for a service and he adds 40 for each hour he works so that is why this is the answer Remember the total bill cost 215 so that comes as the equation is equal to.

Hope that helps

Someone help me ASAP!!!! I need this ASAP!!!!

So to solve it the equation is a squared plus b squared = c squared. So you square a and b. Then do the square root of that and should get c. C is always the largest side. C is opposite from a 90 degree angle . Hope this helps you answer your question.

Two cars leave at the same time from points A and B, the distance between them is 280 km. If the cars meet each other, they’ll m

kykrilka [37]

Set up the following equations:

$2x + 2y = 280$

$14x - 14y = 280$

x represents car A's speed, and y represents car B's speed.

We'll use elimination to solve this system of equations. Multiply the first equation by 7:

$(2x + 2y = 280) * 7 = 14x + 14y = 1960$

$14x - 14y = 280$

Combine both equations:

$28x = 2240$

Divide both sides by 28 to get x by itself:

$x = 80$

The speed of car A is 80 mph.

Since we now know the value of one of the variables, we can plug it into the first equation:

$2(80) + 2y = 280$

$160 + 2y = 280$

Subtract 160 from both sides.

$2y = 120$

Divide both sides by 2 to get y by itself:

$y = 60$

The speed of car B is 60 mph.
