One way to prove that the triangles are congruent is to show that the three pairs of sides have the same length.

For side BD, this is easy, since it is shared by the two triangles, so it is obviously equal.

On the other hand, we know that the given figure is a parallelogram, the opposite sides are equal in length. Particularly, it means that:

AB = CD \quad\textrm{and}\quad BC = AD.

Thus, we have shown that each pair of sides have the same length, which means that:

\triangle ABD \equiv \triangle CDB.

42x+25y=486, x+y=14<br>show work please help asap!​
ruslelena [56]
Rewrite equations:
x+y=14;42x+25y=486

Step: Solvex+y=14for x:
x+y=14
x+y+−y=14+−y(Add -y to both sides)
x=−y+14

Step: Substitute−y+14forxin42x+25y=486:
42x+25y=486
42(−y+14)+25y=486
−17y+588=486(Simplify both sides of the equation)
−17y+588+−588=486+−588(Add -588 to both sides)
−17y=−102
−17y
−17
=
−102
−17
(Divide both sides by -17)
y=6

Step: Substitute6foryinx=−y+14:
x=−y+14
x=−6+14
x=8(Simplify both sides of the equation)

Mrs. Clever mixes 1.24 liters of red paint with 3 times as much blue paint to make purple paint. She pours the paint equally int
Contact [7]
Amount of blue paint = 1.24 x 3
= 3.72
amount of blue paint in each container = 3.72/5
= 0.744

0.744 litres of blue paint is in each container.

Wat is the scientific notation for 0.00000012 and 0.000005008
gtnhenbr [62]
Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become 1.2* 10^{-7}
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become 50.08* 10^{-7}
Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are 1.2* 10^{-7} and 50.08* 10^{-7}

Serggg [28]

Answer:

The second choice is correct. (f(x) = 8.50x+7.50)

Angel had +7.50 dollars to start off with and then worked 5 hours to get 42.50  dollars. This means, she earns 8 dollars 50 cents per hour, meaning that 8.50x would represent the total amount of money that she would earn from her job.

Let me know if this helps!
