What are the steps to find the value of b ?
vazorg [7]
The angles should add to 540, so
b+ (3/2)b+(b+45)+(2b-90)+90=540

First combine like terms
5.5b+45=540

Then subtract 45 from both sides
5.5b=495

Divide both sides by 5.5
b=90

Final answer: b=90

Katen [24]

She wants to serve --------- >  2 gallons of juice that is 75% orange juice and 25% pineapple juice

then 

2*0.75------------------ > 1.5 gallons of orange juice

2*0.25------------------ > 0.5 gallons of pineapple juice


2 gallons------------ >1.5 gallons of orange juice+ 0.5 gallons of pineapple juice

if 1 gallons pineapple juice mixture--------------------- > 0.40 gallons pineapple juice

X------------------------------------------------------------------- > 0.50 gallons pineapple juice

X=50/40=1.25 gallons juice mixture

1.25 mixture gallons---- > 0.50 gallons pineapple juice+0.75 gallons orange juice

Therefore

(2-1.25)=0.75 gallons of orange juice

2 gallons------------ >0.75 gallons of orange juice+ <span>1.25 mixture gallons  </span>

0.75*(p)+1.25*(m)=2--------------- > (0.75/1.25)*(p)+(1.25/1.25)*m=2/1.25

0.60p+m=1.6

 The answer is 0.60p+m=1.6
