Answer:

-2/5

Step-by-step explanation:

We can use the slope formula

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

= ( 18-8)/(-15-10)

= 10/-25

= -2/5

For which equation is x=0 NOT a solution?

Nimfa-mama [501]

B, is the only solution where x=0 isn’t the answer because 2.5x+3=x and if u subtract the 2.5x you get 3= -1.5x and if you divide 3 by -1.5 it won’t be x=0

If George is 33 1/3% richer than Pete, than Pete is what percent poorer than George?

OleMash [197]

Answer:

25%

Step-by-step explanation:

George is 33 $\frac{1}{3}$ % ( $\frac{100}{3}$ %) richer than Pete. Let Pete's percentage of wealth be 100%.

Thus George percentage of wealth = 100% + $\frac{100}{3}$ %

= $\frac{400}{3}$ %

= 133 $\frac{1}{3}$ %

Pete's percent poorer than George can be determined by;

= $(\frac{100}{3})$ ÷ $(\frac{400}{3} )$ × 100

= $(\frac{100}{3})$ × $\frac{3}{400}$ ×100

= 0.25 × 100

= 25%

Pete is 25% poorer than George.

$\\ \sf\longmapsto 0.49=\dfrac{49}{100}$

$\\ \sf\longmapsto 0.093=\dfrac{93}{1000}$

$\\ \sf\longmapsto 0.021=\dfrac{21}{1000}$

$\\ \sf\longmapsto 0.103=\dfrac{103}{1000}$
