-1.825. you subtract 16.2 from 1.6. then divide that number by 8
Answer:
The answer is below
Step-by-step explanation:
Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles every day from now on. The total number of miles walked y can be represented by y = 2.5x + 5, where x is the number days walked after today. a. State the x- and y-intercepts and then graph the equation. b. Interpret the x- and y-intercepts.
Solution:
The equation for a linear function is given by:
y = mx + b; where m is the slope of the function and b is the y intercept.
Given the equation y = 2.5x + 5, the y and x intercept can be found by substituting x = 0 and y = 0. Hence:
a) x intercept is the value of x when y = 0. Therefore:
0 = 2.5x + 5
2.5x = -5
x = -2
y intercept is the value of y when x = 0. Therefore:
y = 2.5(0) + 5
y = 5
b) The x-intercept is at the point (–2, 0). But there cannot be a negative number of days walked, hence the x intercept does not apply in this situation.
The y intercept is at the point (0, 5). This means that Yosune has initially walked her dog 5 miles.
Answer:
n = 1
Step-by-step explanation:
Solve for n:
-9 (6 - 4 n) = 2 (9 n - 12) - 12 n
2 (9 n - 12) = 18 n - 24:
-9 (6 - 4 n) = 18 n - 24 - 12 n
Grouping like terms, 18 n - 12 n - 24 = (18 n - 12 n) - 24:
-9 (6 - 4 n) = (18 n - 12 n) - 24
18 n - 12 n = 6 n:
-9 (6 - 4 n) = 6 n - 24
Expand out terms of the left hand side:
36 n - 54 = 6 n - 24
Subtract 6 n from both sides:
(36 n - 6 n) - 54 = (6 n - 6 n) - 24
36 n - 6 n = 30 n:
30 n - 54 = (6 n - 6 n) - 24
6 n - 6 n = 0:
30 n - 54 = -24
Add 54 to both sides:
30 n + (54 - 54) = 54 - 24
54 - 54 = 0:
30 n = 54 - 24
54 - 24 = 30:
30 n = 30
Divide both sides of 30 n = 30 by 30:
(30 n)/30 = 30/30
30/30 = 1:
n = 30/30
30/30 = 1:
Answer: n = 1
Answer: 56
Step-by-step explanation: because 8x7=56
Multiply the decimal version of the percent by the total number of hours in a day (24). For example, 26% of the day is 0.26 * 24 = 6.24 hours.
