Combine like terms -2/3p + 1/5 - 1 + 5/6p

1/6p - 4/5

Explanation: -2/3p needs to have the same denominator as 5/6p so they can combine. (Note, whatever sign is in front of a number determines if it is negative or positive. Your equation indicates that the bolded parts are negative and the other parts are positive: -2/3p + 1/5 - 1 + 5/6p. So what we are really doing in an equation like this is combining some numbers together)
-2/3p and 5/6p and the least common multiple of six, so we adjust the numbers to each have a denominator of 6. 5/6p is already there, so we need to adjust -2/3p.
We can multiply both the numerator and denominator by 2 to turn -2/3p into -4/6p. -4/6p has the same value as -2/3p, and now it also has the same denominator as 5/6p!
We then have to combine like terms, therefore combining -4/6p with 5/6p. When adding together fractions, the denominator does not change (this is why both numbers must have the same denominators). So our answer will be _/6p. So we combine -4 with 5, giving us one.
Therefore, -2/3p combined with 5/6p is 1/6p.
Now we have to combine our other set of like terms, 1/5 and -1. We can do this the same way that we combined the other numbers.
1/5 and -1 need the same denominator. This is simple because 1 can easily be figured out with any denominator, as long as the numerator and denominator are the same. This would make 1 = 5/5. But we need it negative, so it would be -5/5.
Now that we have common denominators, we can combine!
1/5 - 5/5
Remember what we said before, the solution will have the same denominator, so all we need to do is (in this case) subtract the numerators.
1 - 5 = 4
So that would be -4/5.
With the like terms combined, we just need to put our two combinations (1/6p and -4/5) together!

Our answer: 1/6p - 4/5

I hope that helps!

Angle LON is a straight angle<br> Angle MON= 3x+89<br> Angle LOM=8x+58<br> Find Angle MON:
tresset_1 [31]

Answer:

Angle MON is 98°

Step-by-step explanation:

The measure of the straight angle is 180°

∵ ∠LON is a straight angle

∴ m∠LON = 180°

∵ Ray OM intersects line LN at O

∴ OM divides ∠LON into two angles ∠LOM and ∠MON

∴ m∠LOM + m∠MON = m∠LON

- Substitute m∠LON by 180°

∴ m∠LOM + m∠MON = 180°

∵ m∠LOM = 8 x + 58

∵ m∠MON = 3 x + 89

- Substitute them in the equation above

∴ (8x + 58) + (3 x + 89) = 180°

- Add the like terms in the left hand side

∴ (8 x + 3 x) + (58 + 89) = 180°

∴ 11 x + 147 = 180

- Subtract 147 from both sides

∴ 11 x = 33

- Divide both sides by 11

∴ x = 3

Substitute the value of x in the measure of angle MON to find it

∵ m∠MON = 3(3) + 89

∴ m∠MON = 9 + 89

∴ m∠MON = 98°

Answer me if you need a friend<br><br> Also 5x+25=35<br><br> x=
STALIN [3.7K]

Answer:

x = 2

Step-by-step explanation:

You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 25 from both sides of the equation:

5x + 25 (-25) = 35 (-25)

5x = 35 - 25

5x = 10

Isolate the variable, x. Divide 5 from both sides:

(5x)/5 = (10)/5

x = 10/5

x = 2

x = 2 is your answer.

30. Justify Reasoning The quotient of two negative integers results in an integer. How does the value of the quotient compare to
Ratling [72]
The quotient of 2 negative integers results in an integer.
-4/-2 = 2
the value of the quotient is positive whereas, the value of the original 2 integers are both negative. The reason being, is that when u divide two negatives, u get a positive.

Answer:

15 = 0.025

16= 3 years

Step-by-step explanation:

15.

I=prt

15= (200)(r)(3)

200(3) = 600r

15 divided by 600r = 40 (0.025)

------------------------------------------------------

16.

I=prt

t= \frac{I}{Ixp} \\t= \frac{90}{0.05x600} \\t= 3

t= 3 years
