I'm assuminng you want to find x and y
eliminate
hmm
eliminate y's
3 times 2=6
multiply first equation by 2 and 2nd by 3 and add
16x-6y=-32
<u>15x+6y=-123 +</u>
31x+0y=155
31x=155
divide both sides by 31
x=5
sub back
5x+2y=-41
5(5)+2y=-41
25+2y=-41
minus 25 both sides
2y=-66
divide by 2
y=-33
(x,y)
(5,-33)
The degree is 3.

To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.
3/4-(3/10+1/4)
Step 1:Change the denominators so that way they are all the same
3/4=15/20
3/10=6/20 15/20-(6/20+5/20)
1/4=5/20
Step 2: Begin solving the problem
6/20+5/20=11/20
15/20-11/20=4/20
Step 3: Simplify your answer
4/20=1/5
Step 4 (is optional): Write your answer in a complete statement
The three girls walk 1/5mile together to school
Answer: A
I hope this is correct and if not I apologize for giving false information.
Answer:
j / 9 = 5
j = 45
Step-by-step explanation:
j / 9 = 5
Multiply each side by 9
j/9 * 9 = 5*9
j = 45
Answer:
m<J = 83
m<L = 97
m<M = 97
Step-by-step explanation:
The corners across (left to right/right to left) from each other of a trapezoid are always equal.
So, it would be like this:
Angle J is equal to angle K
Angle M is equal to angle L
See how they are across from each other?
Therefore, Angle J will be 83 degrees.
To find the other 2 angles subtract 83 from 180
180 - 83 = 97
So, Angle L and M are 97 degrees.
To check your answer you can add up all the corners and they should equal 360 degrees:
83 + 83 + 97 + 97 = 360
360 = 360
