Answer:
5 x 7 = 35
50 - 35 = 15
Step-by-step explanation:
if five times a number subtracted from 50 is 15, do the multiplication of 5 and come out with two numbers when subtracted, you can get the 15.
so I multiplied 5 and 7, and got 35. then I subtracted it from the 50 and got the 15.
(12 + x) X 4.
EXPLANATION
Replace twelve with 12.
Replace the sum with a +
Replace a number with a variable
replace four times with X 4.
Have a gud day
Answer:
I believe your answer would be the following:
A) 250 miles in 5 hours.
C) 200 miles in 4 hours
E) 700 miles in 14 hour
Step-by-step explanation:
Unit rate = 50
A) 250 miles in 5 hours // 50*5 = 250 (CORRECT)
B) 300 miles in 5 hours // 50*5 ≠ 300 (WRONG)
C) 200 miles in 4 hours // 50*4 = 200 (CORRECT)
D) 240 miles in 4 hours // 50*4 ≠ 240 (WRONG)
E) 700 miles in 14 hours // 50*14 = 700 (CORRECT)
Hope this helps! :)
Answer: f(n) = 0.9 × f(n − 1) + 10, f(0) = 175, n > 0
Step-by-step explanation:
Given: A store had 175 cell phones in the month of January.
Every month, 10% of the cell phones were sold and 10 new cell phones were stocked in the store.
Let n be the number of months
Then when n=0
f(0)=175
After first month , n=1
The number of cell phone in store=
Thus 
Similarly we can do till n months, we get
f(n)=0.9×f(n−1)+10, f(0) = 175, n > 0
