Answer:24
Step-by-step explanation:
So first, we want to substitute in 15 to all the x variables.
So,
3x - 8y = 5
Becomes
3 * 15 - 8y = 5
Or,
45 - 8y = 5
So here, you can subtract 45 from both sides to move all like terms to one side.
-8y = 5 - 45
And then simplify:
-8y = -40
Then divide both sides by -8
y = 5
Statements that are always true are:1. Several congruent angles are formed.4. Supplementary angles are formed.Other statements are not always true when a transversal crosses parallel lines.
6 miles = 1in
9 miles = 1 1/2in
12 miles = 2in
and it goes on, hope this helps!
this gives
total area of the field = 4655 sqyrd + 1884.79 sqyrd = 6539.79 sqyrd
cost of fertilising 1 sqyrd = $ 0.08
so cost of fertilising 6539.79 sqyrd = 6539.79 * $ 0.08 = $ 523.18
