Question

помогите решить уравнения,x/80=120/2,Y+38=600-180,m-(479+221)=1400,500/a+175=200,1000-d=551

Answer 1

x/80=120/2

х/80=60

х=60*80

х=4800

 

Y+38=600-180

Y+38=420

Y=420-38

Y=382

 

m-(479+221)=1400

m-700=1400

m=1400+700

m=2100

 

500/a+175=200

500/а=200-175

500/а=25

а=500/25

а=20

 

1000-d=551

d=1000-551

d=449
