If angles 7 and 1 are supplementary, so are 5 and 1 because angle 7= angle 5. Supplements are not always equal. Imagine a more acute angle. One would be, say, 30, and the other would be 150. These numbers are different, so it would be the second option.

Which value of w makes 14=11+w/8 times 6 a true statement?

Vlad [161]

Answer: For the value of w=4, $14=11+\frac{w}{8}\times 6$ is a true statement.

Step-by-step explanation:

Since, the given expression,

$14=11+\frac{w}{8}\times 6$

= $14=11+\frac{6w}{8}$

= $14=11+\frac{3w}{4}$

= $3=\frac{3w}{4}$ ( by subtraction property of equality)

⇒ $=\frac{w}{4}$ ( By division property of equality)

⇒ w=4 ( By multiplication property of equality)
