Answer:
y = 7x + 24
Step-by-step explanation:
m = 7
y = mx + b
3 = 7(-3) + b
24 = b
y = 7x + 24
Maybe 6,5,4,3,2,1,0 i think
15/64
Find a common factor 15 and 64 have.
15 is odd, and the only two factors 15 has is 3 and 5.
64 cannot be divided by 3 or 5.
15/64 is already simplified.
Answer:
10 miles
Step-by-step explanation:
Setting up an equation where the variable 'x' = the number of miles, we can find the total mileage for the passenger's trip:
$6 = $0.75x + $2.25
$6 = the total amount of the trip
$0.75 = the cost for each mile after the initial 5 miles
$2.25 = the flat fee for the first 5 miles
Solve for 'x', subtract $2.25 from both sides: 6 - 2.25 = 0.75x + 2.25 - 2.25 or 3.75 = 0.75x
Divide by 0.75: 3.75/0.75 = 0.75x/0.75 or x = 5 miles
Since the passenger was charged in additional 5 miles, then the total mileage is 10 miles.
Answer:
84
Step-by-step explanation:
Let the first digit = x
Let the second digit =y
x + y = 12
x + 4 = 3*y
===========
From the second equation, we learn that x = 3y - 4
Put that into the first equation.
3y - 4 + y = 12 Combine the left side
4y - 4 = 12 Add 4 to both sides
4y = 16 Divide by 4
4y/4 = 16/4
y = 4
=================
x + 4 = 12
x + 4 - 4 = 12-4
x = 8
So the number is 84
