Answer:
Step-by-step explanation:
Givens
d1 = d
d2 = 75 - d
r1 = x
r2 = x + 7
t = 3
Equation
x*t + (x + 7)*t = 75
This equation represents the total distance travelled. Neither one of the cyclists have gone 75 miles, but they both have gone distances that equal a total of 75 miles.
Solution
3x + (x + 7)*3 = 75
3x + 3x + 21 = 75
6x + 21 = 75
6x = 54
6x/6 = 54/6
x = 9
Answer
The first cyclist is going 9 miles / hr
The second cyclist is going 16 miles / hour
Y=7+2x......(1)
put this value in 4y+x=1
4(7+2x)+x=1
28+14x+x=1
15x=-27
x=-27/15.....(2)
put this value in eqn (1)
y=7+2(-27/5)
y=7-54/5
y=-3.8
I really hope this helps :D:D:D!!!!
Answer:
In other words: any of the prime numbers that can be multiplied to give the original number. ... Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers).
Infinity, because there is no set amount of years the price can rise. The price and keep rising as long as he rents, and it's stated that he will not ever buy a house
