4x + y = 54
8x + 2y = 104
8x + 8y - (8x + 2y) = 240 - 104
6y = 136
y=22 2/3
4x+ 22 2/3 = 54
4x= 31 1/3
x= 7 5/6
17.82 because you just take the 18% of 99 which is 0.18
Sum= 348. you didn't have to regroup because no number went over 10
2n-10<28
+10 +10 adding 10 to both sides to get the variable alone
2n<38
_____ divide both sides by 2 to get n by itself on one side
2
n<19
Check:
(2(18))-10<28
36-10<28
26<28 .......................IT WORKS!!!
Answer:
y = 3x + 6
Step-by-step explanation:
Since the line is parallel, it has the same slope -- 3
y = 3x + b, sub point (1, 9)
9 = 3(1) + b
9 = 3 + b
b = 9 - 3
b = 6
y = 3x + b -- y = 3x + 6
