Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$

A survey of college students resulted in the following information:

AnnyKZ [126]

Answer:

Shoe survey:

1.) 34 people were surveyed

2.) 8 people own Adidas ONLY

Allergies:

3.) 14 people not allergic

4.) 9 people are allergic to milk

5.) 23 people are allergic to 1 thing or " less than 2 foods"

6.) They said "or" in the question but here's both answers: 14 to milk and 18 to banana

Love the Actors:

7.) 21 people like Will Smith

8.) 2 people who don't like either

Step-by-step explanation:

1.) It said 20 people own BOTH brands so subtract 20 from the Nike shoes & Adidas shoes, giving 4 people who only use Nike and 8 people who use Adidas, don't forget the 2 who have neither. Add 20+4+8+2=34

2.) As we found out (above) there are 8 people who use Adidas

3.) Keep in mind there are 50 people were surveyed, add all the numbers

( =36) then subtract 50 (the total) minus 36 giving you 14

4.) Add 6( only milk) + 3( banana &milk)= 9

The rest is to long and don't want to keep you wanting

Perform the addition. (3x² + 3x - 5) + (-7x² + 9)

lakkis [162]

The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
$(3 x^{2} + 3x - 5) + (-7 x^{2} + 9)$ 
Use distributive property:
 $3 x^{2} + 3x - 5 - 7 x^{2} + 9$
Combine Like Terms:
$
-4 x^{2} +3x+4$
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
