Trini took some photos the number of photos she took is a two-digit number the sum of the digits is 11 the tens digit is 3 more than the ones digit how many photos did trini take

Trini took 74 photos

Solution:

Given that Trini took some photos

The number of photos she took is a two-digit number

Let the number in unit place be  x  and the number in tens place be  y

Then the two digit number is yx

Given that sum of digits is 11

Therefore,

x + y = 11 eqn 1

The tens digit is 3 more than the ones digit

Therefore, we frame a equation as,

y = 3 + x eqn 2

Solve eqn 1 and eqn 2 to get value of "x" and "y"

Substitute eqn 2 in eqn 1

x + 3 + x = 11

2x + 3 = 11

2x = 11 - 3

2x = 8

x = 4

Substitute x = 4 in eqn 2

y = 3 + 4 = 7

Thus the two digit number is 74. Thus he took 74 photos

answer: options?

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
