Erica, sheena, and yaei are playing a game. eric has half as many points as sheena. sheena has three fewer points than yaei. together the three players have 68 points. how many points does yaei have? algebraic formula answer

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
