y = 2x – 5. –8x – 4y = –20. one solution: (–2.5, 0)
Answer:
Your answer is that the magazine would cost $1.33 per issue.
Step-by-step explanation:
There are 12 months in a year and we get one issue per month, so we need to divide the cost 15.96 by 12 to find out the price per month. Your answer is that the magazine would cost $1.33 per issue.
The measure of angle 2 is 
Explanation:
Given that 
and 
are complementary angles.
Also, the measure of angle 1 is 
We need to determine the measure of
Since, we know that the complementary angles add up to 90°, then the angles and add up to 90°.
Thus, we have,
Substituting the value of in the above expression, we have,
Subtracting both sides by 76°, we get,
Simplifying, we have,
Thus, the measure of angle 2 is
The first one is 5%
Second - 76 is 15 percent of what number? If we substitue "what number" in the question "76 is 15 percent of what number?" with 506.67, we get this sentence: 76 is 15 percent of 506.67. Since this statement is true, we know that our answer is correct.
Third - 25 percent (calculated percentage %) of what number equals 50? Answer: 200.
Answer:
R___S___T
RT=RS+ST
39 = (23 - 2x) + (9x - 5)
39 =7x + 18
7x = 39 - 18
7x = 26
x = 26/7
x= 3.7
RS= 23 - 2x = 23 - 2(3.7) = 23 - 7.4 = 15.6
If went ST = 9x -5 = 9(3.7)- 5 = 33.3 - 5 = 28.3
I hope I helped you^_^
