Answer:
13. 16+16-16+16x = 16+16x
Answer: 124
Step-by-step explanation:
Multiply 320 by 3/5 (.6) and you will get 192. Then you subtract 320 by 47 and get 316. You subtract 192 from 316 and get 124.
4x+4y=-9
first change into yintercept form
y=-x-9/4
to find yintercept let x=0
y=-0-9/4
y=-9/4 or -2.25
to find xintercept let y=0
0=-x-9/4
x=-9/4
so the x and y coordinates are -2.25 and -2.25 respectively
From the rules of modular arithmetic, (A+B)mod C= (A)modC +(B)modC
So, (m + dk) mod d = (m) mod d+<span> (dk) mod d
clearly </span>(dk) mod d = 0, as one of the things (dk) mod d represents, is the remainder of dk, when divided by d, which is clearly 0.
Thus
(m + dk) mod d = (m) mod d+ (dk) mod d= (m) mod d+ 0=(m) mod d
(m + dk) mod d =(m) mod d
N/13 = 15 with a remainder of 12:
Multiply both sides of this eq'n by 13, to eliminate fractions:
15N = 13(15) + 12 = 195 + 12 = 207
Let's check our answer.
Divide 13 into 207. Using a calculator, we find the quotient is 15.923.
The remainder is 0.923 times 13, or 12.
The number N is 207
