Answer:
x=60
Step-by-step explanation:
Given that ,
HCF of 140 and x=20,
LCM of 140 and x =420.
Solution:
It is known that the product of two numbers is equal to the product of their HCF and LCM, i-e:
140*x= HCF*LCM
Putting in the values provided,
140*x=20*420
140*x=8400
x=8400/140
x=60
Hence the variable x is 60.
Answer:
5,040 cars
Step-by-step explanation:
Each truck weighs 7.2 tons, and there are already 480 trucks loaded. This means that the cargo ship is currently carrying 3,456 tons.:
480 x 7.2 = 3,456
The limit is 21,600 tons, so 21,600 - 3,456 = 18,144.
Divide the remaining capacity by how much a car weighs:
18,144 / 3.6 = 5,040
X = -5.
Add 3 to each side, -8 + 3 = -5
Answer:Thx so much.
