Answer:
60
Step-by-step explanation:
100 x 0.4 = 40 and that is the discount so you subtract that off the price so 100 - 40 = 60
Answer:
c. BC
Step-by-step explanation:
It is the possible one
Answer:

Step-by-step explanation:
Given that Gemma has hiked 2 1/3 mile each hour for a total of 3 hours, you can multiply her rate by her time to find the total distance:
d = rt or d = 2 1/3(3)

Multiply: 
Now, that the total length of the trail, 11 3/8 miles, and subtract the distance that Gemma has gone already:
11 3/8 - 7 = 
Answer:
and
.
Step-by-step explanation:
Let
be the smaller one of the two number.
must be a positive integer. The other number would be
.
The question states that the product of the two numbers is
. In other words:
.
Rearrange this equation and solve for
:
.
The first root of this quadratic equation would be:
.
Similarly, the second root of this quadratic equation would be:
.
Since the question requires that both numbers should be positive,
. Therefore, only
is valid.
Hence, the two numbers would be
and
, which is
.
Answer:
y = 2x - 3
Yes, your answer is correct.
Step-by-step explanation:
First, find the slope of the two points by using the slope formula:
y2 - y1
m = -------------
x2 - x1
13 - 5
m = -------------
8 - 4
8
m = ------- = 2
4
To find the y-intercept, plug in values into the slope-intercept formula:
y = mx + b
Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):
5 = (2) (4) + b
5 = 8 + b
-3 = b
b = -3
So, putting everything into the slope intercept formula:
y = 2x - 3
