Answer:
x=5
y=0
Step-by-step explanation:
KL = JM
3x-y = 15
and JK = LM
4x -4y = 20
Divide this equation by 4
x-y= 5
Multiply by -1
-x+y =-5
Add this to the first equation
3x-y = 15
-x+y =-5
-----------------
2x = 10
Divide by 2
2x/2 = 10/2
x =5
x-y = 5
5-y = 5
-y = 0
y =0
Answer:
1106 1/2
Step-by-step explanation:
Average = sum of scores / number of scores
That’s
323 + 429 + 2718 + 956 /4
4426/4
Divide by 2
2213/2
1106 1/2
Saturn takes 17.6 more years than Jupiter, so 17.6 + 11.9 will get you how long Saturn will take to orbit the sun, which would give you 29.5 years.

Step-by-step explanation:
Answer:
x = 3.5
y = 11.75
Step-by-step explanation:
-9x - 2y = -55
6x - 4y = -26
Step 1:
-2(-9x - 2y = -55) → 18x + 4y = 110
Step 2:
18x + 4y = 110
<u> 6x - 4y = -26</u>
<u> 24x </u>= <u>84</u>
24 24
x = 3.5
Step 3:
6(3.5) - 4y = -26
21 - 4y = -26
<u> -21 -21 </u>
<u> -4y </u>=<u> -47</u>
-4 -4
y = 11.75
