-4n-4-n-2

-4n-n-4-2

-5n-4-2

-5n-6
Answer 2
Answer:

Answer:

-(5 n + 6)

Step-by-step explanation:

Simplify the following:

-4 (n + 1) - (n + 2)

-4 (n + 1) = -4 n - 4:

-4 n - 4 - (n + 2)

-(n + 2) = -n - 2:

-4 - 4 n + -n - 2

Grouping like terms, -4 - 4 n - 2 - n = (-4 n - n) + (-4 - 2):

(-4 n - n) + (-4 - 2)

-4 n - n = -5 n:

-5 n + (-4 - 2)

-4 - 2 = -(4 + 2):

-5 n + -(4 + 2)

4 + 2 = 6:

-5 n - 6

Factor -1 out of -5 n - 6:

Answer: -(5 n + 6)

A 56 kg miniature horse weighs 268 fewer kilograms than shetland pony

Answers

let
x--------> Shetland pony's weigh
y--------> Miniature horse's weigh

we know that
y=56 kg
x=268+y \n x=268+56 \n x=324 kg

the answer is
Shetland pony's weigh is 324 kg
If the mini horse is 56kg and it's 268kg less than a Shetland pony then a Shetland pony would weigh 56+268=324kg

How can you solve problems involving equations that contain addition, subtraction, multiplication, or division?

Answers

Well it all depends on the problem but you have to approach every problem with the order of operations PEMDAS. In order you do parentheses, exponents, multiplication, division, addition, then subtraction. If you post an example of the problem you're trying to work out we can be more specific.

Two angles are supplementary. The measure of the first angle is 10 degrees more than three times the second angle. Find the measure of each angle

Answers

Answer:

137.5° and 42.5°

Step-by-step explanation:

supplementary angles are two angles whose sum is equal to 180°.

Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.

we know that the sum of first and second angles is 180° (supplementary angles)

so, (3(x)+10°)+(x) = 180°

                   4(x) = 170°

                       x = 170°/4 = 42.5°

so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°

therefore, the angles are 137.5° and 42.5°.
