Answer:
A =28.26
Step-by-step explanation:
Using the area formula
A = pi r^2
We use pi = 3.14 and the radius is 3
A = 3.14 * (3)^2
A = 3.14 *9
A =28.26
4s + 5 = 19
First, subtract 5 from both sides. / Your problem should look like: 4s = 19 - 5.
Second, simplify 19 - 5 to 14. / Your problem should look like: 4s = 14.
Third, divide both sides by 4. / Your problem should look like: s =

.
Fourth, simplify

to

. / Your problem should look like: s =

which is the answer.
The 12 is multiplied by 4 to get 48, and
the (5r + 6t) is multiplied by 6 to get (30r + 36t), therefore
you are multiplying the outside by 4 and the inside by 6, putting
those together is 24 for a factor.
If 12(5r + 6t) = w, then
48(30r + 36t) is equal to 24w.
The answer is y=(1/3)x+7, use y=mx+b and solve for b where m is slope
380 - 18% of 380
= 380 - (18/100)×380
= 380 - 68.4
= 311.6
