Answer:y=24 and x=10
Step-by-step explanation:
To find the value of x and y in x=3x-20 and y=-6+30
We gets
y=24
To get x
x=3x-20
Collect like terms
x-3x=-20
Divide through by -2
-2x=-20
x=10
It would be 7/3 as you times the whole number by the denominator. Then add the numerator to get the numerator of your answer, finally add the original denominator to your answer to equal 7/3 .

Answer:



Step-by-step explanation:
Given
Similar Triangles: ABC and DEF



Required
Determine the sides of DEF
No options were given, so I will solve on a general terms.
Since both triangles are similar, then the following relationship exists.
DEF = ABC * n
i.e.

Where

Assume n = 2.
So, we have:







Assume 
So, we have:







So, the possible sides are:
