A is the midpoint of BC.
BA = 3x+8
AC=23.
solve for x

Answers

Answer 1

Since A is the midpoint of BC, we can assume BA and AC are equal to each other.

We also know that BC = BA + AC = 23 + 23 = 46

Answer 2
Since A is the midpoint of BC, A divides BA and AC equally.
Therefore, BA=AC.
Since BA=AC,
3x+8=23
Or, 3x= 23-8
Or, 3x= 15
Or, x=15/3
Therefore, x=5.
Ans: x=5.

jamie's string is 10ft 1in long. emma's string is 6ft 4in long. how much longer is jamie's string

Answers

Answer:

Jamie's string is 3ft and 9in

Step-by-step explanation:

10ft 1in

-6ft 4in

=3ft 9in

Answer:

3ft 9 in

Step-by-step explanation:

So, in each foot there's 12 inches. Knowing that, the operation you use is subtraction. So you do 10 ft 1 in - 6 ft 4 in. If you do that operation knowing that 12 inches=1 foot, then you should get 3 ft 9 in.

Point O is between points Mand N on line segment MN. O is the midpoint of line segment MN if

Obviously if O is the *mid*point, then it is exactly halfway between M and N. That also means it has bisected the segment into two equal parts.
On one side you have MO (or OM, if you like)
On the other side you have ON.
In order for O to be the midpoint:
ON = OM

Solve 0.5y+y/3=0.25y+7​
please answer this question

Answers

Answer:

y = 28

Step-by-step explanation:

0.5y + y/ 3 = 0.25y + 7

1.5y / 3 = 0.25y + 7

y/2 = 0.25y + 7

y = ( 0.25y + 7)*2

y = 0.5y + 14

y - 0.5y = 14

0.5y = 14

y = 14/0.5

y = 28
