So if she got them at 30% off that means
$63 = 70%
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price
$90 = 100%
original price was $90
Answer: z=1/2 or 0.5
Step-by-step explanation: 1. Subtract 19/2 to both sides. 13-19/2 is equal to 7/2 or 3.5." So then you're left with 7z=3.5
2. Divide by 7 to both sides. 3.5/7= 0.5.
3. z=0.5
The slope intercept form is
y = Mx + b
x and y are the coordinates, and m is the slope. If you don’t have b, you can plug in the other numbers you do have.
EXAMPLE:
A line has a slope of -3 and a coordinate of (1, 6). What is the y-intercept (b)?
y = Mx + b
6 = -3(1) + b
6 = -3 + b
9 = b
Answer:
a/5
Step-by-step explanation:
You can choose a random number for a and see which is greater. For example, you can say a = 40.
That would mean a/5 = 8 and a/8 = 5. Since 8 is greater than 5, a/5 will always be greater.
Frank has at least a month of jogging left. Seriously, he couldn't make it more than a quarter of a mile? Frank is clearly out of shape. His best bet at this point is to put down the Big Mac and hit the gym.
Also, here's the real answer:
2/3-1/4
8/12-3/12
5/12
Frank has 5/12 mile left
