8/16 is one half so 4.50(4 1/2) so the answer is 2.25
Answer:
10
Step-by-step explanation:
6 3/4 ÷ 3/4 = 9, and plus the sign at the start of the road it would be 10
hope this helps :)
Answer:
(1,2)
(3,3)
(-1/2, 11/2)
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Substitution can be used by substituting the value of one variable into the equation.
<u>Pair x=3y-5 and x+y=3</u>
Because x=3y-5, we can substitute 3y-5 into x in x+y=3
x+y=3
(3y-5)+y=3
3y-5+y=3
4y-5=3
4y-5+5=3+5
4y=8
y=2
We now substitute y=2 into x=3y-5.
x=3y-5
x=3(2)-5
x=6-5
x=1
<u>Pair y=x and 3x+3y=18</u>
Because y=x, we can substitute x into y in 3x+3y=18
3x+3y=18
3x+3x=18
6x=18
x=3
We now substitute x=3 into y=x.
y=3.
<u>Pair y=-3x+4 and 5x-y=0</u>
Because y=-3x+4, we can substitute -3x+4 into y in 5x-y=0
5x-y=0
5x-(-3x+4)=0
5x+3x+4=0
8x+4=0
8x=-4
x=-1/2
We now substitute x=-1/2 into y=-3x+4
y=-3x+4
y=-3(-1/2)+4
y=3/2+4
y=11/2
Given that Trent's watch runs at half the speed it should run, this implies that
for every hour passed, his watch moves by half an hour.
Hence, for every half-hour passed, Trent's watch moves by 15 minutes.
Hence, when the real time is 10:30 am, Trent's watch will show 9:15 am.
Answer:
both Jenna and Mia got the same answer because the answer they got is correct but they used their own techniques to reach for the answer.
Mia's steps are time efficient enough by shortening the length of the sum and jumping steps...
Jenna is also correct in her own way, she wrote the full steps and explanation of the answer stepwise which is time consuming but cannot be wrong at the end throughout the steps. Even if she gets wrong she can quickly find the place of the mistake.
