James answered 14 items correctly on a 16-item quiz. what percent did he answer correctly?
Troyanec [42]
So,

I like to simplify a fraction first.  This is what I do when I'm in a store trying to find the unit price.

\frac{14}{16}

Factor.
\frac{2*7}{2*2*2*2}

Cross out ones.
\frac{7}{2*2*2}

Multiply it out.
\frac{7}{8}

In my head, I remember that one-eighth is equal to 0.125.

So seven-eighths is equal to 0.125 times 7.
0.125 * 7 = 0.875

Convert to percent form.
0.875 --> 87.5%

James answered 87.5% of his quiz correctly.

I actually have the decimal equivalents for eighths in my head when I'm shopping.  So once I get seven-eighths, I immediately know how much that is.  I can also subtract 0.125 from 1.000 to get seven-eighths.

-1+(-3) is blank units from -1 in the blank direction
Thepotemich [5.8K]

-1+(-3) is  3 units from -1 in the left direction

-1+(-3) is blank units from -1 in the blank direction

-4 is  3 units from -1 in the left direction

because we know that

in the real line if we go 3 units in left from -1 we get -4

since in the real number line

the pattern is ................ - 5, -4, -3, -2, -1 ,0,1,2,3,4,5,............

thus we get  

-1+(-3) is blank units from -1 in the blank direction

-4 is  3 units from -1 in the left direction

Answer:

x = 52

Step-by-step explanation:

28 + x - 4 + 2x = 180

Simplify the left side

3x + 24 = 180

Subtract 24 from each side

3x = 156

Divide each side by 3

x = 52
