Answer:the third option is the correct answer
Step-by-step explanation:
The given system of linear equations is expressed as
y – 3x = –2 - - - - - - - - - - - -1
y = 4 - - - - - - - - - - - - - 2
The first step is to substitute equation 1 into equation 2. It becomes
4 – 3x = –2
Subtracting 4 from the left hand side and the right hand side of the equation, it becomes
4 - 4 - 3x = –2 - 4
- 3x = - 6
Dividing the left hand side and the right hand side of the equation by - 3, it becomes
- 3x/ - 3 = - 6/ - 3
x = 2
(2, 4)
The answer is J
The rides she wants to ride cost 4+6+3 tickets so that goes on one side. She already has 7 tickets so you need to know 7 plus what will get her on those rides so those go on the other side. So you have:
7+t=4+6+3
Then you solve for t
7+t=13
t=13-7=6
Hope that helps.
Answer:
6 minutes
Step-by-step explanation:
- Set up the proportion as these two fractions equal to each other
9/3 = 18/x
2. Cross multiply so that 9*x=18*3
3. 9x=54, so now you divide 54 by 9
and this will give you
4. x= 6, so it will take 6 minutes to fill
up the 18 gallon pool
Hope this helped!
Answer:
6.5 inches
Step-by-step explanation:
It moves up about 1/2 of an inch per day, so we just multiply 13 by 1/2 and that equals 6.5 inches. I hope this helped and please mark me brainliest!
