Answer:
a. 19
Step-by-step explanation:
5/6x-1/5x=19
5/6(30)-1/5(30)=19
25-6=19
19=19
?/30(30)=19
19/30(30)=19
19=19
I'm not sure if this is exactly what you're looking for, but 19=19 if you plug in 19 for the box (and x=30 because of the first section, I'm guessing)
The answer is option 4, (-1,2)
Answer:
72 and -2
Step-by-step explanation:
x - y = 74
2x + 3y = 138
x - y = 74
y = x - 74
2x + 3(x - 74) = 138
2x + 3x - 222 = 138
5x = 360
x = 72
x - y = 74
72 - y = 74
-y = 2
y = -2
Answer: x = 25/123
Step-by-step explanation:
I’m pretty sure the answer is -7 B
