Urgent: due tonight or i get a water tank holds 252 gallons but is leaking at a rate of 3 gallons per week. a second water tank holds 378 gallons but is leaking at a rate of 5 gallons per week. after how many weeks will the amount of water in the two tanks be the same? offering 30 !

63 weeks

Step-by-step explanation:

252 - 3x = 378 - 5x

       + 5x          +5x

Add 5x to both sides

252 + 2x = 378

-252         - 252

Subtract 252 from both sides

2x = 126

Divide 2 from both sides

x = 63

Check you work by plugging 63 where the x is

252 - 3(63)

252 - 189 = 63

378 - 5(63)

378- 315 = 63

where is the page?

step-by-step explanation:

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
