Help please can’t get this wrong. Am I doing this right if not correct me. And how do I write it

a<-7/2 or a>1

Step-by-step explanation:

2a+5<-2 or -4a-1<-5

2a<-2-5 -4a<-5+1

2a<-7. -4a<-4

2a/2<-7/2 -4a/-4<-4/-4

a<-7/2 a>1

<-7/2 or a>1

i dunno how to explain i just got it.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

27 +27 or 27times 2=54

the diffrence is 0
