According to my calculations, the y intercept is 22.8
I know it's late but,
25 ft ÷ 4 cm = 6.25
500 ÷ 6.25 = 80
750 ÷ 6.25 = 120
and so your answer is C.<span> 80 centimeters by 120 centimeters
and again sorry it's late :D</span>
No that wouldn't work.
e.g 1/2 + 1/2 would become 2/4 (which is equivalent to 1/2) if you just added the numbers, which can't be right.
You need to find equivalent fractions so that each fraction has the same number on the bottom (denominator) and then add ( or take away) the top numbers.
1/2 + 1/2 has same number on bottom, so just add top numbers to get 2/2 =1
so 1/4 + 1/2 has diff nos on bottom, so change 1/2 to 2/4.
1/4 + 2/4 = 3/4
2/3 - 1/4 = 8/12 - 3/12 = 5/12
You may need to ask your teacher about equivalent fractions.
Answer:
30mph faster
Step-by-step explanation:
first you must find how fast the train can go in 1 hour
that is 60mph, then multiply 60 and 2.5
60x2.5 = 150mph then,
150 - 120 =30mph
very sorry if this is wrong
