which of the following is the missing reason? Statements Reasons three halves times x plus 5 equals negative 4 Given 3x + 10 = −

den301095 [7]

Answer:

The missing reason is Subtraction Property of Equality.

Step-by-step explanation:

$\frac{3}{2}x+5=-4$ ⇒ (Given)

On Solving we get;

Multiplying 2 on both side we get;

$2(\frac{3}{2}x+5)=-4\times2\\\\2\times \frac{3}{2}x+5\times 2=-4\times 2$

$3x+10=-8$ ⇒ (Multiplication Property of Equality)

Now Subtracting Both side by 10 we get;

$3x+10-10=-8-10$

$3x = -18$ ⇒ (Subtraction Property of Equality)

Now Dividing both side by 3 we get;

$\frac{3x}{3} = \frac{-18}{3}$

$x=-6$ ⇒ (Division Property of Equality)

Hence the missing reason is Subtraction Property of Equality.

Answer: 65°

<u>Step-by-step explanation:</u>

$E=w(t_f-t_o)\\\\E: 10\ cubic\ feet\times \dfrac{1000\ BTU}{1\ cubic\ foot}\times \ 60\%\quad \rightarrow \quad E=6000\ BTU\\\\\\w:50\ gallons\times \dfrac{8\ pounds}{1\ gallon}\quad \rightarrow \quad w=400\ pounds\\\\\\\\E=w(t_f-t_o)\\\\6000=400(t_f-50)\\\\\dfrac{6000}{400}=\dfrac{400(t_f-50)}{400}\\\\.\quad 15=t_f-50\\\\\\.\quad 15=t_f-50\\.\ \underline{+50}\quad \underline{\quad \ +50}\\.\quad 65=t_f$

Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents.

Brilliant_brown [7]

9514 1404 393

Answer:

85°
60°

Step-by-step explanation:

1. Angle JKL is half the measure of the intercepted arc JK.

(1/2)JK = 1/2(360° -190°) = (1/2)(170°) = 85°

angle JKL is 85°

2. The angle between tangents is the supplement of the intercepted arc.

angle JKL = 180° -(360° -240°)

angle JKL = 60°
