Answer:
Fist you add 5 to the -5 and 11. Then you should get 3x=16. Next you divide 3 on both sides. Your answer should be x=16/3.
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
We know that point C is in the middle of point A and point B.
That means that when these two equations are added they should be equal to the length of AB which is 41.
5x+3x-7=41
add 7 to both sides
8x=48
divide both sides by 8.
x=6
Answer: It should cost $5
Step-by-step explanation:
First you have 4 hardcover and 2 softcover, so 4x+2y= $24 and for your friend it would be 3x+3y= $21.
You have
(3x+3y)2 = 72
(4x+2y)3 = 42
Then subtract them which is 30 you would divide by 6 since 3x2=6
Which gets you to 5.
Answer:
6%
Step-by-step explanation:
Given,
Interest (I) = 2160
Principal (P) = 12000
Time (T) = 3 yrs
Rate (R) = ?
We know that,
R = ( I *100)/ (P*T)
= (2160*100)/(12000*3)
= 6%
therefore, the rate of interest is 6%
