Solve the rational equation quantity 3 times x minus 5 end quantity divided by 7 equals four sevenths. x = −1.33
x = 3
x = 4
x = 4.67

idk. Did you figure it out?

Step-by-step explanation:

x = 3

Step-by-step explanation:

Took test

(Please give me brainiest to help me reach the next level, only a few more brainiest to go!)

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.
