Answer:

Step-by-step explanation:

Using PEMDAS we know that you start with parenthesis, which would give us twenty within the brackets. Then you would solve for the exponent, which would give you sixteen but you do not add the exponent to the parenthesis until you divide. 100 divided by 20 is five, then you add ten and sixteen, giving you 31.

A photograph was enlarged to a width of 15 inches. If the scale factor was 3 /2 , what was the width of the original photograph?

andre [41]

If the width is 15, and the scale factor from width to length is 3:2, then you will have to divide 15 by 3 to get your original width.
15/3 = 5.
5 is your original width.

Solve for x: -4x - 12 < 12

aliina [53]

Seems like you are an imposter ;). This is Middle School math.

Anyways...

Answer:

x>6

Step-by-step explanation:

-4x-12<12

Add 12 on both sides.

-4x<24

Divide both sides by -4 to isolate x. Remember that if you are dividing by a negative, flip the sign!

x>6

Hope this helps!
