Answer:
53/6  = 8.83
Step-by-step explanation:
2 x -7 = -14
-62 / 12 = -5.16667
-5.16667 - (-14) = 8.83333
Final answer: 8.83

Answer:
Step-by-step explanation:
so we are looking for the x intercept (where the line crosses the x axis).
to do this, we sub in 0 for y and solve for x.
y = 1/2x + 4....sub in 0 for y
0 = 1/2x + 4
-1/2x = 4
x = 4 * -2
x = -8 <=== so it crosses the x axis at (-8,0)
 
        
             
        
        
        
Answer: 3 red marbles, 3 blue marbles, 6 yellow marbles, 8 black marbles, 4 silver marbles 
Step-by-step explanation:
I know these are the correct number of marbles because I set up these numbers as fractions and solved for x. 
For examples, 2/16 of the marbles are red. 2/16=x/24
You would do this because we are trying to find the number of marbles that are red out of the 24 marbles.
Next, we would do 24 divided by 16= 1.5 Then 1.5 times 2=3
You would follow this rule for each fraction of marbles in order to find the true number of marbles out of 24.
