Answer:
278 tons
Step-by-step explanation:
Given data
Train A and Train B, weigh a total of 366 tons
A+B= 366----------1
We are also given that
A-B= 190-----------2
from 1
A= 366-B
put this in equation 2, we have
366-B-B= 190
366-2B= 190
366-190= 2B
176=2B
divide both sides by 2
B= 176/2
B=88 tons
Put B= 88 in equation 1 to find A
A+88= 366
A= 366-88
A=278 tons
Hence Train A is 278 tons
72 inches
The perimeter is the sum of the outside "fence"
The side on the left that is not marked is 19-11 = 8
And the side on the top that is not marked is 17-10 = 7
Summing up the sides starting at 19 and going clockwise
19+17+11+7+8+10 =
46
The HCF of 168 & 196 is 28
The factors of 168 are: 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
The factors of 196 are: 1, 2, 4, 7, 14, 28, 49, 98, 196
The highest factor that both 168 and 196 share is 28
Hope this helps :D
What number is represented by point B = -1
Which point represents the number 2? = C
x < 3
Isolate the variable by dividing each side by factors that don't contain the variable.
