What are the last 2 digits of 7 to the power of 2018. This question was on a past exam paper.
Xelga [282]

Answer:

49

Step-by-step explanation:

  • Try finding pattern of last two digits of 7 to the power of some numbers.

7^1=07

7^2=49

7^3=343

7^4= 2301

7^5= 16807

  • so , the pattern is, 07,49,43,01
  • so, if we start writing all numbers from 1 to 2018 , four number in each line, 2018 will fall in the second column.
  • so it will have 49 as the  last 2 digits [by seeing this pattern : 07,49,43,01 ]

It’s for my geometry class and I don’t know how to solve it. Can someone please help me?
dusya [7]

Answer:

Below in bold.

Step-by-step explanation:

Because the 2 sides marked with the double lines are equal:

5y-1 = 2y+11

3y = 12

y = 4.

Also :

3x-5 + 2(2x+5) = 180

3x - 5 + 4x + 10 = 180

7x = 180 + 5 -10

7x = 175

x = 175/7 = 25.
