So cost=50+75t
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
Answer:
If the numbers were the same, they'd both be 61
So, try 60 and 62.
x + x+2 = 122
2x = 120
x = 60
Hope that helps!
Answer:
4/8 or 1/2
Step-by-step explanation:
7/8-3/8= 4/8 or 1/2
There are 2 solutions. the highest degree of a polynomial is 2
Step-by-step explanation:
a) gradient= y2-y1/x2-x1
gradient of AB:
gradient=-4-1/2-3
=-5/-1
=5
gradient of BC:
=-5+4/7-2
=-1/5
b) as the priduct of both gradient is -1 ,both lines are perpendicular.
c) as we have seen lines are perpendicular so it is a right angled triangle.
