Y=x+3
-3x+3(x+3)=4
-3x+3x+9=4
9=4
Since this statement is false, there are no ordered pair solutions to this problem.
Multiply both sides by 2
(2) 18 = x/2 (2)
the /2 (2) gets canceled out
so it's 36= x
Hope this helps
Tax = 7.65% of $23, 750
Tax = 0.0765 x 23750

You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
Answer:
x = 40
Step-by-step explanation:
Angles SRT and STR are congruent, so they have the same measure.
The measure of <SRT is 20, so the measure of <STR is also 20.
Angles STR and STU form a linear pair. Two angles that form a linear pair are supplementary, so their measures add up to 180.
m<STR + m<STU = 180
20 + 4x = 180
4x = 160
x = 40
