70 miles per hour, just divide 210 between 3
Answer:
Step-by-step explanation:
"A number is<u> [WHAT?] </u>of another number." It appears the <u>WHAT??</u> is missing. If it is a word such as "twice," it can be solved in this fashion.
Let the numbers be X and Y, with Y the larger number.
A number is <u>twice</u> another number: Y = 2X
The difference of the numbers is 18: Y - X = 18
Use the first equation (Y = 2X) in the second by replacing "Y" with (2X):
Y - X = 18
2X - X = 18
X = 18
Y = 2X, so Y = 36

D is correct
3(2x-5)=6x+k
6x-15=6x+k
If 2 equations are identical the solution will be infinite
