HELP PLEASE!! ASAP <br> If triangles ABC and DEF are similar, what is y? Show your work.
Ivenika [448]

Answer:

y = 18

Step-by-step explanation:

Since the triangles are similar, the corresponding sides are in proportion, that is

\frac{BC}{EF} = \frac{AC}{DF} , substitute values

\frac{y}{12} = \frac{21}{14} ( cross- multiply )

14y = 252 ( divide both sides by 14 )

y = 18

What is the value of n in the equation 0.2(n - 6) = 2.8?<br> (1) 8 (3) 20<br> (2) 2 (4) 44
Vera_Pavlovna [14]
So,

0.2(n - 6) = 2.8

Distribute.
0.2n - 1.2 = 2.8

Add 1.2 to both sides.
0.2n = 4

Divide both sides by .2.
n = 20

Check.
0.2(20 - 6) = 2.8

Simplify inside parentheses.
0.2(14) = 2.8

Multiply.
2.8 = 2.8 This checks.

S = {2.8}
