Answer: x = 17
Step-by-step explanation:
Hi there!
First, since we know that these two lines are parallel, 3x+14 is going to be congruent to the supplementary side of 7x-4. Given this, we are able to solve for x as we know that the sum of supplementary angles is 180. All you have to do is set up 3x+14+7x-4=180
Now, just use simple order of operations and combining like terms to isolate x. you will end with 17! :)
Hope this helps!
for which value of x does each expression make sense:
(square root) -2x^2
(square root) (-2x)^3
Answers
The value of x that makes sense for the expression is the domain of the expression
The value of x makes sense for [tex]\sqrt{-2x^2}[/tex] is 0The value of x must not exceed 0 for [tex]\sqrt{(-2x)^3}[/tex] to make sense[tex]\sqrt{-2x^2}[/tex]
For the above expression to have a defined value, the expression in the bracket must be positive.
However, x^2 will always be positive, and -2 will ensure that the expression is always negative, except when x = 0
Hence, the value of x makes sense for [tex]\sqrt{-2x^2}[/tex] is 0
[tex]\sqrt{(-2x)^3}[/tex]
For the above expression to have a defined value, the expression in the square root must be positive.
However, the power of 3 will ensure that the expression is always positive only when x is less than or equal to 0
Hence, the value of x must not exceed 0 for [tex]\sqrt{(-2x)^3}[/tex] to make sense

(1) [tex]\frac 28 + \frac 24 =[/tex]
Take LCM
[tex]\frac 28 + \frac 24 = \frac{2 + 4}8[/tex]
[tex]\frac 28 + \frac 24 = \frac{6}8[/tex]
Simplify
[tex]\frac 28 + \frac 24 = \frac 34[/tex]
(2) [tex]\frac 9{10} - \frac 35 =[/tex]
Take LCM
[tex]\frac 9{10} - \frac 35 =\frac{9 - 6}{10}[/tex]
[tex]\frac 9{10} - \frac 35 =\frac{4}{10}[/tex]
Simplify

(3) [tex]\frac 46 - [\ ]=\frac{2}{6}[/tex]
Replace the blank with x
[tex]\frac 46 -x=\frac{2}{6}[/tex]
Collect like terms
[tex]x = \frac 46 -\frac{2}{6}[/tex]
Take LCM
[tex]x = \frac{4 - 2}{6}[/tex]
[tex]x = \frac{2}{6}[/tex]
Simplify
[tex]x = \frac{1}{3}[/tex]
(4) [tex]\frac{}{12} + \frac 26 = \frac{2}{12}[/tex]
Replace the blank with x
[tex]\frac{x}{12} + \frac 26 = \frac{2}{12}[/tex]
Collect like terms
[tex]\frac{x}{12} = \frac{2}{12} -\frac 26[/tex]
Take LCM
[tex]\frac{x}{12} = \frac{2 - 4}{12}[/tex]
[tex]\frac{x}{12} = -\frac{2}{12}[/tex]
Multiply both sides by 12

(5) [tex]\frac{9}{18} - \frac{3}{9}[/tex]
Take LCM
[tex]\frac{9}{18} - \frac{3}{9} = \frac{9 - 6}{18}[/tex]
[tex]\frac{9}{18} - \frac{3}{9} = \frac{3}{18}[/tex]

Suppose ΔDEF has an exterior angle at vertex D. The measure of the exterior angle is (8x−2)º, m∠E=(3x−8)°, and m∠F=(4x+13)°. What is the measure of the exterior angle at vertex D?
A. 7°
B. 13°
C. 41°
D. 54°
Answers
The measure of the exterior angle at vertex D is: D. 54°
Recall:
The exterior angle theorem of a triangle states that the measure of an exterior angle equals the sum of the measures of two opposite interior angles of the triangle.Thus:
In ΔDEF, (8x−2)º is an exterior angle at vertex D.
m∠E = (3x−8)° (interior angle)
m∠F = (4x+13)° (interior angle)
Therefore:
(8x−2)º = (3x−8)° + (4x+13)°
Solve for x8x - 2 = 3x - 8 + 4x + 13
Combine like terms8x - 2 = 7x + 5
8x - 7x = 2 + 5
x = 7
Exterior angle at vertex D = (8x−2)º
Plug in the value of x= 8(7) - 2

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
On Monday, Eric biked = 1 Km 125 m
= 1.125 Km
On Tuesday, Eric biked = 1.125 Km - 375 m
= 1.125 - 0.375 Km
= 0.75 Km
So, Eric biked on both day
=1.125 + 0.75
