Answer:
x = 7 and y = 17
Step-by-step explanation:
16x + 9x + 5 = 180 cuz they are supplementary
25x = 175
x = 7
We also know that 16x + 4y = 180
so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17
hope this makes sense
Mode is the number that appears most often in a set, so for this one the mode would be 3 since it appears the most often
y= -8 or 8
Step-by-step explanation
30-6= 24
24/3=8
y=8
15+y=7
y=-8
