My best guess is D.
But I'm not too sure about it.
Answer:
See below
Step-by-step explanation:
From noon to 1500 is three hours
train A then travels <u> 3x</u> where x = speed in km/hr
train B only travels for 2.45 hours and covers
<u> 2.45 ( x + 15) </u> where x + 15 is its speed in km/hr
these two values sum to the 300 km distance
3x + 2.45 ( x + 15) = 300
3x + 2.45 x + 36.75 = 300
x = 48.3 km/hr x+15= 63.3 km / hr
Answer:
X < -1
Step-by-step explanation:
4x - 5 + X < -10
5x < -5
× < -1
3/4 To find the slope of a line you need to do rise/run. you find two solid points meaning find two points are exactly on a intersection. Then you count up how much it needs to the point then count across to the next point
Answer: 14.7 grams
Step-by-step explanation:
Given : Henry has two pixie sticks full of delicious sugar.
Each pixie stick has 22 grams of sugary goodness.
Then, Total sugary goodness in 2 pixie sticks= 
Total persons = 3 [Including himself]
If he divides 2 sticks evenly among 3 persons , then the amount of sugary goodness each persons will receive
= Total sugary goodness in 2 pixie sticks divided by 3
grams
Hence, He will share 14.7 grams of sugary goodness with each of his friends.
