Answer:

<h3>HERE IS YOUR ANSWER FRIEND, </h3>

∠A + ∠B + ∠C = 180° (angle sum property)

(4x - 13)° + (15)° + (2x + 18)° = 180°

( 4x - 13 + 15 + 2x + 18 )° = 180°

( 6x + 20)° = 180°

6x = 180 - 20

6x = 160

x = 160/6

x = 80/3° (or 26.6666666667 )

we have value of x = 80/3°

°.°∠A = ( 4x - 13 ) = 281/3

°.°∠C = ( 2x + 18 ) = 178/3

Can you solve 4 + 2/3 x = -5 in fraction form?
guapka [62]

Answer:

\frac{-27}{2} = (-13)(\frac{1}{2})

Step-by-step explanation:

The given equation is 4 + 2/3 x = -5

Taking variable on one side and constants on other side, we get

-9 = (\frac{2}{3})(x)

x = (\frac{3}{2})(-9) = \frac{-27}{2} = (-13)(\frac{1}{2}) = -13.5

The number in decimal form is given by -13.5

The number in fraction form is given as \frac{-27}{2} = (-13)(\frac{1}{2})

Using a property of operations, what can you say about the sums of (-13.2) 8.1 and 13.2 (-8.1)
artcher [175]
No matter where the negative sign is, the product will always be negative, so is the number itself.

13.2(-8.1)=-106.92

twice of that would be -213.84.

first do the multiplying, then the adding(the adding of negative numbers, so it would be basically subtracting).
