Answer:
x = 5
Step-by-step explanation:
3x - 2 = x + 8
Subtract x from each side
3x-x - 2 = x-x + 8
2x -2 = 8
Add 2 to each side
2x-2+2 = 8+2
2x = 10
Divide each side by 2
2x/2 =10/2
x = 5
Answer:
A
Step-by-step explanation:
4 ----- 2/3
15 ----- ????
multiply 15 by 2/3 and divide the result by 4 and you will get the answer.
The answer is F.30
Explanation: If we do guess and check, if we multiply the ratios by 10, it would be 30:40:50, which doesn’t add up to 180 degrees. if we multiply the ratios by 20, It would be 60:80:100, which also doesn’t add up to 180 degrees. How about we multiply the ratios by 15? It would be 45:60:75, which does add up to 180! The difference between x and z is 30, so the answer is F.30
Answer 2.43
Explanation: I did the math but seriously if you want a explanation comment and i’ll explain the process
Slope = (-6 - 3)/(1+2) = -9/3=-3
y - 3 = -3(x +2)
y - 3 = -3x - 6
3x + y = -3
answer is 3x + y = -3 (third one)
