180=11+2x
-11 -11
169/2=2x\2
x=84.5
Answer:
21
Step-by-step explanation:
8x+y, when x=2 and y=5,
then 8*2+5. Because the 2 is right next to the 8, it isn't '82', but '8*2'
According to PEMDAS, multiplication is done first, so
8*2= 16,
16+5, which is 16+5= 21
Answer:
12 remainder 3 (or 12.3)
Step-by-step explanation:
123/10=12.3
you can't really have .3 of a book, so 12 remainder 3 or three groups of 13 and 7 groups of 12.
Answer:
(-3 , 0)
Step-by-step explanation:
The x-intercept is the point on which lies on the x-axis, so when the y is equal to 0.
They y-value can be seen as gaining 16 whole numbers every time the x gains 3.
1. Add intervals of +16 to the y-value (from -32) and intervals of +3 to the x-value (from -9) until the y-value equals 0.
Show:
(-9+3 , -32+16) = (-6 , -16)
(-6+3 , -16+16) = (-3 , 0)
The y-value in the end, is 0 with a x-value of -3.
You need the odd integers to be separated by 2. One will not work.
If n is odd, n + 1 will be even. You cannot get an exception to that. Try it.
1 is odd but 1 + 1 is even.
n and n + 3 produces 1 odd and 1 even. If n is odd then since 3 is odd when the two are added together, you get an even. Again try it
n = 5
n + 3 = 8
C: is not the answer.
D can't work either. If n is odd then n + 2 will be odd but n + 1 is even.
The Answer is B.
n(n + 2) = 195
n^2 + 2n - 195 = 0
(n - 13)(n + 15)
n can be 13 and n + 2 can be 15
13 * 15 = 195
But here's something you may not know
n can be - 15 and then the other odd number would be - 13
