HIS walking rate was 1 mile per hour because 20min times 3 is 1 hour, and 1/3 times 3 is 1 mile thus 1mph if can plz mark brainliest
It is not digital because that would something like applepay. It is also nt representative, since that would be something like food stamps. Commodity money is also a bad answer, since it is goods. You answer would be fiat money, which is paper tender issued by the government. Hope this helps.
Answer x = 12 and y = 9
Step by step
First identify the equations
The sum of two numbers is 21
x + y = 21
Change to y intercept for ease of math
y = 21 - x ( call this equation a)
Three times the larger is equal to four times the smaller
3x = 4y (call this equation b)
Now substitute the value of y = 21 -x into equation b
3x = 4(21-x)
Distribute
3x = 84 - 4x
Now we want to isolate x by adding 4x to each side
3x + 4x = 84 -4x + 4x
Combine like terms
7x = 84
Now solve for x by dividing both sides by 7
x = 12
Now to find y
Using equation a from above
y = 21 - x
Substitute our x value of 12 into equation
y = 21 - 12
solve for y
y = 9
Now check your work
x = 12 and y = 9
The sum of two numbers is 21
12 + 9 = 21
Three times the larger (x) is equal to four times the smaller (y)
3x12 = 4x9
36 = 36

Answer:
1.944
Step-by-step explanation:
if the problem was written just like the 2.4(0.81) then yes you multiply
Answer:
F = 
Step-by-step explanation:
Given
C = 
( multiply both sides by 9 to clear the fraction )
9C = 5(F - 32) ← distribute
9C = 5F - 160 ( add 160 to both sides )
9C + 160 = 5F ( divide both sides by 5 )
= F
