1) Find x, if 1/3 of x is 14
BartSMP [9]

"of" means multiply      and         "is" means equal

1. \frac{1}{3}x = 14

                                x = 14(3)      <em>multiply both sides by 3 to isolate "x"</em>

                                x = 42

2. \frac{1}{5}x = 14

                                x = 14(5)      <em>multiply both sides by 5 to isolate "x"</em>

                                x = 70

3. \frac{2}{5}x = 14

                                2x = 14(5)      <em>multiply both sides by 5 </em>

                                2x = 70

                                  x = 35         <em>divide both sides by 2 to isolate "x"</em>

4. \frac{7}{8}x = 14

                                7x = 14(8)      <em>multiply both sides by 8 </em>

                                7x = 112

                                  x = 16         <em>divide both sides by 7 to isolate "x"</em>

I really need help on this !!
Naddik [55]

Answer:

r = -1

Step-by-step explanation:

(y2-y1)/(x2-x1)=m

(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5

so plug in...

(4-7)/(4-r)=-3/5

then solve for r which will get that r = -1

numerator: 4-7=-3

denominator: 4-r=5 -> 4-5=0+r -> -1=r
