D=rt
distance = rate*time
rate=15mph
time=3.5hours
distance = 15*3.5 = 52.5
He will travel 52.5 miles in 3.5 hours assuming his rate does not change.
If the equation is in the form of y = mx + C, where m and C are real numbers, the slope (which means gradient) of the line is the coefficient of x (I.e. the number to the left of x in simple language), which is m.
In this case, m = 54 and C = -13pie. Both are real numbers, which means that this equation satisfies the form of y = mx + C
m is the coefficient of x, which is 54. 54 is the gradient of this line, which means that for every 54 y-axis units the line increases, the line increases 1 x-axis unit.
Hope this helps! :)
Answer:
48
Step-by-step explanation:
Wrong : right
1 :12
Multiply by 4 because she gets 4 problems wrong
1*4 : 4*12
4 :48
If she gets 4 problems wrong, she gets 48 problems right
A = P (1 + r)^n where P = initial amount, r = interest rate , n = number of years and A = amount after n years.
So here we have A = 1393(1 + 0.09) ^ 2 ( 0.09 = 9%)
= $1655.02 (answer)
