They hiked more on the 2nd day because they are retracing their steps.
The question is kinda hard to see I’m sorry can you post it again
Answer:
Wanda brought 9 carrot sticks.
Step-by-step explanation:
- Convert 30% to a decimal by removing the percent sign and dividing by 100: 30 ÷ 100 = 0.30
- Substitute 0.30 for 30% in the equation: 30% x 30 = Y becomes 0.30 * 30 = Y
- Do the math: 0.30 x 30 = 9
- Y = 9
- So 30% of 30 is 9
- Double check your answer with the original question: How many carrot sticks did Wanda bring? Multiply 0.30 x 30 = 9
The point-slope form:

We have

Therefore
the point = (2, 1)
the slope = 7
The slope 
7 units up and 1 unit right.

Other method.

It's the slope-intercept form.
for x = 0 → y = 7(0) - 13 = 0 - 13 = -13 → (0, 13)
for x = 2 → y = 7(2) - 13 = 14 - 13 = 1 → (2, 1)
Answer:
Step-by-step explanation:
(x + 200)20 = 200(10) + x(40)
20x + 4000 = 2000 + 40x
2000 = 20x
X = 100 mL
