The question is not clear. As much as i understand it:
3x-12=21
3x=21+12
3x=33
x=11
4x=s
(plug in the value of x, as found in the previous step)
4(11)=s
44=s
hope i helped.
Answer:
D. 7 +11i
Step-by-step explanation:
In many situations, you can treat "i" as though it were a variable. Collect terms in the usual way.
(2 +8i) -(-5-3i) = 2 +8i +5 +3i = (2+5) +(8+3)i
= 7 +11i
Answer is A. y=3/4+10
Remember rise/run the line goes down 3 times and to the right 4 times. The 10 is the y-intercept basically where the dot/line starts
Answer: A+C=500
7.5A+4.75C=3351.25
C=500-A
7.5A+4.75(500-A)=3351.25
7.5A+2375-4.75A=3351.25
2.75A=976.25
A=355 adults ($2662.50)
C=500-A=145 children ($688.75)
