12 can go into 54 only 4 times because 4•12 is 48. Now 56-48=6 so this is the remainder 6/12 wish can be simplified to 1/2 so your answer is 4 1/2 or 4.5. Hope this helps <333
Answer:
See below.
Step-by-step explanation:
Addition: closed
Example: -5 + 10 = 5, and -5, 10, and 5 are all integers
Subtraction: closed
Example: 10 - 8 = 2, and 10, 8, and 2 are all integers
Multiplication: closed
Example: -4 * 7 = -28, and -4, -7 and -28 are all integers
Division: not closed
Example: 5/2 = 2.5, and 2.5 is not an integer, although 2 and 5 are integers
The set of integers is closed under addition, subtraction, and multiplication because any addition, subtraction, or multiplication of integers always results in an integer.
The set of integers is not closed under division because a division of integers does not always result in an integer.
Answer:
16 1/16
Step-by-step explanation:
= 2(x + 4) - (y - 8)
= 2(⅛ + 4) - (3/16 - 8)
= 2(4⅛) - (3/16 - 8/1)
= 2(33/8) - (3/16 - 128/16)
= (2 . 33/8) - (-125/16)
= 33/4 + 125/16
= 132/16 + 125/16
= 257/16
= 16 1/16
Answer:
a=3,b=0,c=5,d=-4/21
Step-by-step explanation:
The formule we use to get the slope is:
m = 
a. (3,2);(4,x); m=1
→ x= (1)(4-3)+2 → 3
b. (b,-1);(2,-2); m=-1/2
→ -1= (
)(2-b) → 
→ 0
c. (5,d);(9,2); m=-3/4
→ d= (
)(9-5)-2 → 5
d. (-1/3,3/4);(h,5/6); m=7/12
→ 
= 
(
) → 
We get this equation with the original one:
y=mx+b
There are three forms of linear equations:
point-slope form y2-y1=m(x2-x1)
standard form Ax + By + C = 0 or Ax + By = C
and slope-intercept form y=mx+b
Answer: B
Step-by-step explanation:
A is incorrect because going from -10 to 10 is not 0, it is 20.
C is incorrect because 21 km from sea level is adding 21.
D is incorrect because the total distance biking to school and back is actually 6.2.
B is correct because buying an item for the same price then selling it for the same price results in no increase in profit but consistency therefore being 0.
