Answer:
i think a.
Step-by-step explanation:
Distribute the 1/3 to the y and the 2
So... (1/3)*y and (1/3)*2
(y/3)+(2/3)+3x=7x
Now subtract 3x from both sides
(y/3)+(2/3)=4x
To get rid of the 3 on the bottom of the fractions, you can multiply both sides by 3 so they cancel out.
y+2=12x
Subtract 2 from both sides to get an equation of
y=12x-2
Answer:
Step-by-step explanation:
To find the value of x, using Pythagorean theorem.
7) x² = 12² + 12²
= 144 + 144
= 288
x = √2*12*12
x = 12√2
8) x² + 9² = 18²
x² + 81 = 324
x² = 324 - 81
x² = 243
x = √3*9*9
x = 9√3

Answer:
1/10
Step-by-step explanation:
There are 5·4·3 = 60 ways to choose a 3-digit number from 5 digits (no repeats).
There re 1·2·3 = 6 ways to choose a number 5x2 or 5x4 from those digits.
The probability of randomly choosing one of 60 that is one of the 6 is ...
... 6/60 = 1/10
