25/5 would be 5
and in the inequality, it says the d/5 is greater than 28
d=25 is nor a solution to the in equality
<span>Lines a and b are parallel.
<a = 79
<b = 79
</span><d = 79
<z = 180 - 79 = 101
<y = 101
<x = 101
<c = 101
Answer:
x = 4.5
Step-by-step explanation:
there's definitely other ways to solve this, but I used a proportion.

Then you can make this equation:
14x = 3.5 * 18
I solved for it and got 4.5 .
Answer:
a=3x+b/4-x
Step-by-step explanation:
I dont know which variable you're supposed to solve for. But here's how i got the answer above:
Divide each term in a(4-x)=3x+b by 4-x
a(4-x)/4-x=3x/4-x+b/4-x
Then, cancel the common factor of 4-x, giving you
a=3x/4-x+b/4-x
Finally, combine the numerators over the common denominator,
giving you a=3x+b/4-x
