Please see explanation

Step-by-step explanation:

When two integers are being added there can be three cases in the answer

The sum will be positive if both the integers are positive and in case of addition of one positive and negative integer, the sum will be positive if the integer with larger magnitude is positive

The sum will be negative if both integers are negative and in case of addition of one positive and negative integer, the sum will be negative if the integer with larger magnitude is negative

The sum will be zero if both the integers have same magnitude and different signs.

Answer: 86

Step-by-step explanation:

There's a seven digit difference between each number so if you continue adding 7 you'll get 86. -12, -5, 2, 9, 16, 23, 30, 37, 44, 51, 58, 65, 72, 79, 86

Answer:

x = 1

Step-by-step explanation:

- 31 - 4 = - 5 - 25x - 5

− 3 5 = − 5 − 2 5 − 5

− 3 5 = − 2 5 − 1 0

− 3 5 + 1 0 = − 2 5 − 1 0 + 1 0

− 2 5 = − 2 5

− 2 5 = − 2 5

-25/-25 = - 25x/- 25

x = 1

Answer:

X=1

Step-by-step explanation:

1)Subtract the numbers

-31-4=-5-25x-5

-35=-5-25x-5

2)Subtract the numbers

-35=-5-25x-5

-35=-10-25x

3)Rearrange terms

-35=-10-25x

-35=-10-25x

4)Add 10 to both sides of the equation

−35=−25−10

−35+10=−25−10+10

5)Simplify

−25=−25x

X=1

Answer:

The correct option is  [tex]\frac{4}{15}[/tex].

step-by-step-explantion;

It is Given: Three teaches equally shared [tex]\frac{4}{5}[/tex] of a flat of paper that was donated to the school.

Solution:

3 teachers equally shared  [tex]\frac{4}{5}[/tex] of paper.

The fraction of paper each teacher receive = [tex]\frac{4}{5} \div 3[/tex]

The fraction of paper each teacher receive = [tex]\frac{4}{5} \times \frac{1}{3}[/tex]

The fraction of paper each teacher receive = [tex]\frac{4}{15}[/tex]

Hence, the correct option is  [tex]\frac{4}{15}[/tex].

Answer:

It would be 4/15 (b)

Answer:

16 days

Step-by-step explanation:

24 men works 8 hours a day to complete a work in 15 days. While 20 men works at 9 hours per day to complete the same work in x days. We can find the number of days it took the 20 men by using the expression below:

24 men * 8 hours/day * 15 days = 20 men * 9 hours/day * x days

[tex]x (days)=\frac{24\ men * 8\ hours/day * 15\ days }{20\ men * 9\ hours/day} \\\\Simplifying\ gives:\\\\x(days)=16\\\\x=16\ days[/tex]

Therefore it took 20 men working 9 hours/day, 16 days to complete the same work

5(4) is 20. 10(8) is 80. 25(3) is 75. 20+80+75 equals 175. He has a total score of 175.

Answer: 175 points

Step-by-step explanation:

5x4 = 20

10x8= 80

25x3= 75

20+80= 100

100+75=                  175!!!

Answer:

C. A little under 1 year

Step-by-step explanation:

Since Veronica is saving $100 each month.

So,

in the first month she will save = $100

in the second month she will save = $200

in the third month she will save = $300

Following the same pattern, she will accumulate $1100 in 11 month.

11 moths is 1 month less than a year.

So, Veronica will take A little under 1 year to accumulate $1100.
