Answer is 6 miles per day
Answer is equation 48 = (x)(5) + 18
Step by step
You can use y intercept equation
y = mx + b
y = 48 total miles
m = rate of miles unknown
x = 5 days
b = starting point of 18 miles already ridden
48 = (x) (5) + 18
48 = 5x + 18
Subtract 18 from both sides to isolate the variable
48 - 18 = 5x + 18 - 18
30 = 5x
Now divide both sides by 5 to solve for x
30/5 = 5/5 x
X = 6 miles per day
Check your work, substitute 6 for x in your equation
48 = (6) (5) + 18
48 = 30 + 18
48 = 48
Problem solved!!
The answer is 40% and 0.4
Answer:
140 miles
Step-by-step explanation:
4 per day for 5 days a week
= 4x5=20 miles a week
For 7 weeks= 20x7= 140 miles
Answer:2
Step-by-step explanation:
The amplitude is the coefficient of sinx, therefore the amplitude is 2
Using the second equation, let’s find x
x + 7y = 8
x = 8 - 7y
Substitute x in the other equation
3/8(8 - 7y) + 1/3y = 17/24
3 - 21/8y + 1/3y = 17/24
-55/24y = -55/24
y = 1
Plug in y in any equation
x + 7(1) = 8
x + 7 = 8
x = 1
x = 1 and y = 1
