Answer:
48
Step-by-step explanation:
1/4 x = 12
x = 4*12
x=48
Answer:
(2, 14).
Step-by-step explanation:
If a point is on the line then it's coordinates should fit the equation y = x + 7.
The point (0, 7) is on the line because 7 = 0 + 7.
The point not on the line is (2, 14) because 14 is not equal to 2 + 7.
Answer:
$42.84
Step-by-step explanation:
There are two ways to do this.
One
19% of 36 = 19/100 * 36 = $6.84
Total 36 + 6.84 = $42.84
Two
The second method involves knowing that his total is going to wind up being 119% of the bill. That's 100% + 19%
So the equation look like this
(119/100) * 36
or
(119 * 36) / 100 = 4284 / 100 = $42.84
Note
Both methods give you the same answer.
ok, b)
you can times anything inside bracket by 8. so, 8r -40 + 12
You can simplify to 8r - 28.
d)
You can rearrange it to 6a + 12a -12/3 -15/3
= 18a - 27/3
