Which statement explains why –27 is the opposite number of 27? Answer Choices They are the same quantity with different signs. They are an equal distance from 1 on the number line. They are both greater than 0. They are odd numbers.

Answers

Now... -27 and 27 are equally the same number, but in different signs, but they are also same distance from each other. So i'd say: They are the same quantity with different signs.
"They are the same quantity with different signs" is the answer, 27 and -27 are the same  number ( quantity) just one is a positive number and the other is a negative number.

a mail truck picks up two boxes of mail from the post office. the total weight of the boxes is 32 pounds . one box is 8 pounds heavier than the other box. how much does each box weight

Answers

One box is 24lb another box is 8 because i half of 32 is 16 and 1/2 of 166 is 8 so 16 + 8 = 24 leaving another 8 behind

Final answer:

The boxes weigh 12 pounds and 20 pounds respectfully. We found this by setting up and solving an equation based on the problem's parameters.

Explanation:

Let's assume the lighter box weighs 'x' pounds, this makes the heavier box weigh 'x+8' pounds. According to the problem, the total weight of both boxes that the mail truck picks up from the post office is 32 pounds. So, we can set up the following equation: x + (x+8) = 32. Solving this equation we get 2x = 24, which means x = 12. So, one box weighs 12 pounds and the other box, which is 8 pounds heavier, weighs 20 pounds.

Write the sum of the numbers as the product of their gcf and another sum. Problem: 13+52=?

Answers

Answer: Hello mate!

We have the equation 13 + 52 and we want to write this as the product of their GCF and another sum.

The GCF between 52 and 13 can be obtained in the next form:

52/13 = 4, then 52 = 13*4

then 13 is a factor of 52, and 13 is the GCF between 13 and 52.

our equation can be written as:

13 + 52 = 13 + 13*4 = 13*(1 + 4)

there you have the equation written as the product between the GCF between 13 and 52 and another sum.

Find an equation for the line that passes through the point (-3, 6), parallel to the line through the points (0,-7) and (4,-15). Write your answer in point-slope form.

Answers

1st we will have to find the equation of the points (0,-7)(4,-15)
find the slope 1st
slope = y2-y1/x2-x1
slope = -8/4
slope = -2
and we know that the y intercept is -7
thus
the equation would be
y = -2x - 7

now we need to find the equation of the line that passes throgh (-3,6) and parallel to the previous equation
since it is parallel to the previous equation then they have the same slopes
thus the slope is -2
now we need to use
y - y1 = m(x - x1) to determine the equation
subsitute the values of x1 and y1
and m is the slope
y - 6 = -2(x +3)
y - 6 = -2x -6
y = -2x
that's the equation!

What is 1/4 - [-3/8] =

Answers

1/4 - [-3/8]

(1)/(4)- (-(3)/(8))

Negative times negative become positive

(1)/(4) + (3)/(8)

Now to add fractions we make the denominator same

4  and 8 are in the denominator

Least common denominator of 4  and 8 is 8

To make denominators same , we multiply the numerator and denominator of first fraction by 2.

(1*2)/(4*2) + (3)/(8)

(2)/(8) + (3)/(8)

The denominators are same so we combine the numerators

(2+3)/(8)

(5)/(8)

(1)/(4) - ( - 3)/(8) = (5)/(8)
5/8 cross multiply on the top then multiply the denominator you get 20/32 reduce that it's 5/8
