What is the value of x? * HELPPP ME PLEASEE
IM HIVE BRAINIEST TO FIRST PERSON WHO ANSWER, and I HAVE TO SHOW MY WORK

(7x-15) = 180

7x = 195 (add 15 to both sides)

195 / 7 = 27.85

(x + 28) + (4x -3) + 27.85 = 180

5x + 53.85 = 180 (add like terms)

5x = 126.15 (subtract 53.85 from both sides)

x = 25.23 (dived both sides by 5)

Step-by-step explanation:

I could be wrong though

hope this helps

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
