Please HELP!!! DUE TODAY!!
Thank you so much.
Answer:
7:45
Step-by-step explanation:
work backwards from 10:30!
u need 5 min to walk from meeting place to station, therefore u need to done riding the train by 10:25.
then u know that the train is an hour and 30 min, therefore u have to ride the train before or at 8:55 (10:25 minus an hour and a half)
the latest time for the train to leave is 45 min past the hour. therefore you will ride the 8:45 train.
since we already know that we are riding the 8:45 train by latest, you have to leave an hour early to get to the station. so you need to leave home by 7:45.
hope i was helpful !
The latest time that Annabelle can leave home is the she leaves home and she won't be late for her meeting
Time of meeting = 10.30am
Time she will spend before getting to meeting:
home to get to Euston Rail Station = 1 hourtrain journey from Euston to Bimingham = 1 hour 10 minutesTrains to Birmingham = 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.The latest time is 45 minutes
Walk from the meeting venue in Birmingham from the station = 5 minute walkTotal time = 1 hour + 1 hour 10 minutes + 45 minutes + 5 minutes
= 3 hours
Counting 3 hours backward from 10:30 am = 7:30 am
Therefore, the latest time Annabelle can leave home is 7:30 am

Step-by-step explanation:
Functions are defined to map out to only one value so that rules everything else out and leave us with only one answer.

Answer:
addition or subtraction (1.)
Step-by-step explanation:
Answer:
Divide both sides by a constant to simplify the equation. Thus the second option.
Step-by-step explanation:
Solve for x:
9 - 10 x = -1
Hint: | Isolate terms with x to the left hand side.
Subtract 9 from both sides:
(9 - 9) - 10 x = -9 - 1
Hint: | Look for the difference of two identical terms.
9 - 9 = 0:
-10 x = -9 - 1
Hint: | Evaluate -9 - 1.
-9 - 1 = -10:
-10 x = -10
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of -10 x = -10 by -10:
(-10 x)/(-10) = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:
x = (-10)/(-10)
Hint: | Any nonzero number divided by itself is one.
(-10)/(-10) = 1:
Answer: x = 1

Write the standard form of the equation of the circle with radius 7 and center (4,−9).
Answer:
x^2 + y^2 - 8x + 18y + 48 = 0
Step-by-step explanation:
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding
(x-4)^2 + {y-(-9)}^2 = 7^2

Consider matrix A.
What matrix results from the elementary row operations represented by −2R2+3R1?
Answer:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]
Step-by-step explanation:
Given the matrix
[tex]A = \left[\begin{array}{ccc}-3&3&2\\8&-1&3\end{array}\right] \\R1 = -3, 5, 2\\R2 = 8, -1, 3\\\\[/tex]
Before we can get the resulting matrix after the elementary operation, we need to get the new second row using the formula −2R2+3R1?
when R1= -3, R2 = 8
−2R2+3R1? = −2(8)+3(-3)
−2(8)+3(-3) = -16-9
−2(8)+3(-3) = -25
R1= 5, R2 = -1
−2R2+3R1? = −2(-1)+3(5)
−2(-1)+3(5) = 2-15
−2(-1)+3(5) = -13
when R1= 2, R2 = 3
−2R2+3R1? = −2(3)+3(2)
−2(3)+3(2) = -6-6
−2(3)+3(2) = 0
Hence the new R2 are -25, -13, 0
The resulting matrix will be:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]

How do you solve 5x + 7 = 2x + 1
Answer:
x = -2
Step-by-step explanation:
5x + 7 = 2x + 1
subtract both sides by 2x
3x + 7 = 1
subtract both side by 7
3x = -6
divide both sides by 3
x = -2

Seventy students tried out for volleyball but only 20% of those students made the team. How many student's made the team?
Answer:
14 students
Step-by-step explanation:
dont ask i just know
Answer:
14 Students made the team.
Step-by-step explanation:
There are different ways to solve percentages, but I only use one.
[tex]\frac{20}{100}[/tex] • [tex]\frac{x}{70}[/tex] So you cross multiply 20 and 70 which is 1400. Then you divide 1400 by 100 which is 14.
Find the sum.
(n+8)+(n−12)
=
n=2
Reorder terms:
(8+n)+(n-12)=0
Remover first parentheses :
8+n+(n-12)=0
Reorder (again):
8-12+n+n=0
Simplify:
-4+2n=0
Add 4 to both sides:
2n=4
Divide and you’re done!
n=2
