Answer: 4
Step-by-step explanation: If you multiply 3/5 by 3/3, it will turn into 9/15. If you multiply -1/3 by 5/5, it will turn into -5/15. Since it is a negative, you will have to subtract. 9-5 is 4.

Step-by-step explanation:
The sum of interior angles of a polygon of n sides is:
[tex]S=180^\circ (n-2)[/tex]
The image shows a 6-side polygon. The sum of the interior angles is:
[tex]S=180^\circ (6-2)=720^\circ[/tex]
The sum of all the shown interior angles must equal 900°:
[tex]125+100+y+117+121+y+23=720[/tex]
Simplifying:
[tex]486+2y=720[/tex]
Solving:
[tex]2y=720-486[/tex]
[tex]2y=234[/tex]
[tex]y=234 / 2=117[/tex]
y=117°
Thus the angle AFY is:
[tex]\angle AFY=y+23=117+23=140[/tex]
[tex]\boxed{\angle AFY=140^\circ}[/tex]
[tex]\angle LIM=y=117[/tex]

Answer:
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.
Step-by-step explanation:
Using, the formula y1+y2/x1-x2,
Choosing any two points, make the expression:
1-2/125-155
simplify:
-1/-30
the slope of the equation is -1/-30.
to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:
y would be 2
x would be 155
b is the y intercept
2= -1/-30•155 + b
2=5⅙+b
b = - 3⅙
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

How are the rules for dividing two negative fractions related to the rules for multiplying
two negative fractions? Will the answer be positive or negative? Explain.
Answers
The relation between multiplying and dividing two negative fractions is needed.
When multiplying and dividing two negative fractions the answer will be always positive.
Let [tex]-\dfrac{a}{b}[/tex] be one fraction
and [tex]-\dfrac{c}{d}[/tex] be another fraction
Let us multiply them
[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]
Let us divide them
[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]
This can also be written as
[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]
Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.
Hence, when multiplying and dividing two negative fractions the answer will be always positive.

Solve
3x + 8 = 2x + 21
Answers
Answer:
Step-by-step explanation:Simplifying
3x + 8 = 2x + -21
Reorder the terms:
8 + 3x = 2x + -21
Reorder the terms:
8 + 3x = -21 + 2x
Solving
8 + 3x = -21 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
8 + 3x + -2x = -21 + 2x + -2x
Combine like terms: 3x + -2x = 1x
8 + 1x = -21 + 2x + -2x
Combine like terms: 2x + -2x = 0
8 + 1x = -21 + 0
8 + 1x = -21
Add '-8' to each side of the equation.
8 + -8 + 1x = -21 + -8
Combine like terms: 8 + -8 = 0
0 + 1x = -21 + -8
1x = -21 + -8
Combine like terms: -21 + -8 = -29
1x = -29
Divide each side by '1'.
x = -29
Simplifying
x = -29
3x + 8 = 2x + 21
3x - 2x + 8 = 21
x + 8 = 21
x = 21 - 8
x = 13

D) 5/6 as 5/6 = 0.833333333333333 and the three will keep repeating
Answer:
D.
Step-by-step explanation:
You meant which one is a repeating decimal.
Okay to find out you would have to divide each.
4 divided by 5 = 0.8
1 divided by 2 = 0.5
3 divided by 4 = 0.75
5 divided by 6 = 0.833333333...
See how the three keeps on repeating? That makes it a repeating decimal.

Henry makes $12.50 per hour for the first 40 hours he works in a week. For 5 points
each additional hour he makes $18 per hour. How much did he make if he
worked 44 1/2 hours last week? *
Answers
Answer:
He made $581 if he worked 44 1/2 hours last week
Step-by-step explanation:
Let us solve the question
∵ Henry makes $12.50 per hour for the first 40 hours
∵ For each additional hour, he makes $18 per hour
→ We need to find how much he made if he worked 44 1/2 hours
→ At first, find his earning for the first 40 hours
∵ His earning in the first 40 hours = 40 × 12.50
∴ His earning in the first 40 hours = $500
→ Find how many hours he worked after the first 40 hours
∵ 44 1/2 - 40 = 4 1/2 hours
∴ He worked 4 1/2 hours over the first 40 hours
→ Find his earning from them
∵ His earning in 4 1/2 hours = 4 1/2 × 18
∴ His earning in 4 1/2 hours = $81
→ Now add the two amounts to find his total earning
∵ His total earning = 500 + 81
∴ His total earning = $581
∴ He made $581 if he worked 44 1/2 hours last week
