Answer:

x = 12.5

Step-by-step explanation:

The value of x is part of the value of an angle in a triangle where the other angles are known. This suggests that the relevant theorem is the "angle sum theorem," which tells you the sum of angles in a triangle is 180°.

This gives you the equation ...

60° +60° +(4x+10°) = 180° . . . . total of all angles is 180°

4x +130° = 180° . . . . . . . . . . collect terms

4x = 50° . . . . . . . . . . . . subtract 130° from both sides

x = 12.5° . . . . . . . . . divide both sides by 4

lisov135 [29]

Answer:

$16.50

Step-by-step explanation:

If Jason spends $3.75 and Maya spends three times that amount, Maya spends 3.75(3) or $11.25. If Tia spends $5.25 more than Maya, Tia spends 11.25 + 5.25 or $16.50.

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

mariarad [96]

$x_{1}=1$
$x_{2}= 3$
$y_{1} =14$
$y_{2}=4$
$Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5$

answer: The student flipped the y values

Find the solution of 3 times the square root of the quantity of x plus 6 equals negative 12, and determine if it is an extraneou

Anna35 [415]

For this case we have the following equation:
$3 \sqrt{x+6}=-12$
Rewriting we have:
$\sqrt{x+6}= \frac{-12}{3}$
$\sqrt{x+6}=-4$
We raise both members of the equation to the square:
$(\sqrt{x+6})^2=(-4)^2$
Rewriting we have:
$x+6=16$
$x=16-6$
$x=10$
It's a extraneous solution because equality is not met by substituting x = 10 in the original equation:
$3 \sqrt{10+6}=-12$
$3 \sqrt{16}=-12$
$3(4)=-12$
$12=-12$
Answer:
The solution is:
$x=10$
It's a extraneous solution
