Answer:
A. 2y = 22
Step-by-step explanation:
You are basically combining like terms. Look at the equation and subtract from top to bottom.
You will subtract 5x and 5x, 4y and 2y, and 25 and 3.
Now you have 0 + 2y = 22.
Removing the 0 (because it is worth nothing), you will be left with 2y = 22 which corresponds to A.
Answer:
Step-by-step explanation:
The no of different ways in which these restaurants can be visited
= ¹⁵P₁₅
= 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= 1.30 x 10¹²
b ) Each combination takes 1 week and 50 weeks in a year to work
No of years to take to try all the combination
= 1.30 x 10¹² / 50
= 2.615 x 10¹⁰ years .
