Answer:
See below.
Step-by-step explanation:
[tex]\frac{1}{12} +\frac{1}{6} = \frac{2 + 1}{12} = \frac{1}{4}[/tex]
[tex]\frac{1}{4} - \frac{1}{8}=\frac{2-1}{8} = \frac{1}{8}[/tex]
[tex]\frac{2}{3} +\frac{1}{3} = 1[/tex]
[tex]\frac{1}{2} - \frac{1}{6} = \frac{3-1}{6} = \frac{1}{3}[/tex]
Answer:
1/12 + 16 = 1/4
1/4 - 1/8 = 1/8
2/3 + 1/3 = 1
1/2 - 1/6 = 1/3
Step-by-step explanation:
1/12 + 1/6
LCM of denominators 12 and 6 = 12
1/6
Multiply 2 to both numerator and denominator,
1/6 * 2/2
= ( 1*2 )/( 6*2 )
= 2/12
1/12 + 1/6
= 1/12 + 2/12
= ( 1 + 2 )/12
= 3/12
12 = 3*4
3/12
= 3/( 3*4 )
= 1/4
1/4 - 1/8
LCM of denominators 4 and 8 = 8
1/4
Multiply 2 to both numerator and denominator,
1/4 * 2/2
= ( 1*2 )/( 4*2 )
= 2/8
1/4 - 1/8
= 2/8 - 1/8
= ( 2 - 1 )/8
= 1/8
2/3 + 1/3
= ( 2 + 1 )/3
= 3/3
= 1
1/2 - 1/6
LCM of denominators 2 and 6 = 6
1/2
Multiply 3 to both numerator and denominator,
1/2 * 3/3
= ( 1*3 )/( 2*3 )
= 3/6
1/2 - 1/6
= 3/6 - 1/6
= ( 3 - 1 )/6
= 2/6
6 = 2*3
2/6
= 2/( 2*3 )
= 1/3

what's better 27 out of 32 or 19 out of 21 and why
Answers
Because the higher the score the less the points is gonna worth. So if you get one wrong, it wouldn’t hurt your score that much
Answer:
19/21 is better.
Step-by-step explanation:
To find which is better, you need to divide the numerator by the denominator.
27 divided by 32 is equal to 0.84375
19 divided by 21 is equal to 0.9
0.9 is greater than 0.84375, so 19/21 is better.

Need help on algebra 1
Slopes step by step
Answers
Answer:
1 is y=-1/3x. 3 is y=-3/2x. 5 is y=5/3x
Step-by-step explanation:
Simply count the vertical lengths. Meaning count up or down how ever many. That is your top number. Then count your horizontal lengths, meaning left or right, this your bottom number of the slope. So if point A is at (-1,-1) in example 1, then count down 1, and right 3 spaces. Because you go down, the slope is negative, and you went down 1, so the top number is 1, you went right 3 units, so the bottom number is 3.
Solve the inequality b - 12 > -3
What are the solutions?
Answers
Answer:
b>9
Step-by-step explanation:
Answer:
b > 9
Step-by-step explanation:
Inequalities represent the value of a variable in relation to other numbers.
Solving the Inequality
The properties of equality state that if you add or subtract a number from both sides, the statement remains true. This means that we can isolate the variable by using the properties of equality.
To isolate the variable, add 12 to both sidesThis gives the inequality b > 9Understanding the Answer
The answer to the inequality is b > 9. This means that the variable must be greater than 9. So, values such as 10 or 100 could all be solutions. However, remember that 9 itself is not a solution. The inequality only accounts for values greater than 9, not equal to.

It is going up by odd numbers.
So the next term would be 24+12=36
Take the first number.
6+(3×0)=6.
Now add the result with the multiples of 3.
6+(3×1)=9.
9+(3×2)=15.
15+(3×3)=24.
So, the next number in the series is,
24+(3×4)=36.
