Answer:

<u>Quadratic:</u>

a.

c.

e.

i.

j.

<u>Neither:</u>

f.

h.

<u>Linear:</u>

b.

d.

g.

Step-by-step explanation:

Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.

Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.

Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher.  Therefore we can simply sort these equations by the highest exponent of x present after simplifying.

What is 30 percent of 60
Naily [24]

Answer: 18

Step-by-step explanation: Well <u><em>percent</em></u> means <em>over 100</em> so we can set up an equation for this problem by reading it from left to right.

<em>What</em> means <em>x</em>, <em>is</em> means <em>equals</em>, <em>30%</em> is <em>30/100</em>, <em>of</em> means <em>times</em> <em>250</em>.

Simplifying on the right side of the equation,

notice that 30/100 reduces to 3/10.

So we have x = 3/10 · 60. Think of the 60 as 60/1 so we can cross-cancel the 60 and 10 to 6 and 1 and we have x = \frac{(3)(6)}{(1)(1)} or <em>x = 18</em>.

Now let's check our answer back in the original problem to see if it makes sense. We have <em>18 is 30% of 60</em>.

Well we know that 100% of 60 would be 60 so 30% of 60 should be alot less than 60 so 18 seems to make sense as a pretty good answer.
