Complete Question:
Haruka hiked several kilometers in the morning. She hiked only 6 kilometers in the afternoon, which was 25% than she had hiked in the morning.
How many kilometers did Haruka hike in all?
Answer:
10.5 km
Step-by-step explanation:
Given
Represent Morning with M and Afternoon with A

From the second sentence in the question, we have that:

Required
Determine the total kilometers
First, we need to determine the kilometers moved by substituting 6 for A in the second equation




Next, is to determine the total using:



Answer:
y=0
Step-by-step explanation:
Answer:
The sum of interior angles in a triangle is 180°.
So we just have to add Al the angles and equate them to 189°
Step-by-step explanation:

Answer:
The slope is 1 because y2-y1/x2-x1 or -3-3/1-6= -6/-6=1
Answer:
y = -8x
Step-by-step explanation:
First let's look at what slope-intercept form is.
y = mx + b
m is the slope, which in this case is -8.
b is the y-intercept, which we will find later.
Now that we have identified the parts of the equation, let's plug in what we know. Use the point given for your x and y values.
y = mx + b
16 = -8(-2) + b
Let's simplify this to find b.
[multiply] 16 = 16 + b
[subtract 16] 0 = b
We now have our b-value, which is also our y-intercept. Plug in this value into the standard slope-intercept equation.
y = -8x
This is your equation.
Check this by plugging in the point again.
16 = -8(-2)
[multiply] 16 = 16
This expression is true; therefore, your answer is correct.
Hope this helps!
