Answer:
108°
Step-by-step explanation:
The two given angle are vertical angles, which means they are congruent.
(x +81)° = 4x°
81 = 3x . . . . . . . subtract x, divide by °
27 = x . . . . . . . . divide by 3
(27 +81)° = 108° . . . . find the angle measure
The two marked angles have measures of 108°.

Shanice left Kali's house and drove toward
the desert at an average speed of 70 km/h.
Lisa left one hour later and drove in the
opposite direction with an average speed of
55 km/h. Find the number of hours Lisa
needs to drive before they are 570 km apart.
Answer: 4 hours
Make a number line and put up to 5 hours going both directions. one direction will be shanice, the other lisa. youll skip an hour for lisa. so shanice will arrive at 350km and lisa will get to 220km at the five hour mark. It’s a lot simpler then doing the actual math.
what is the slope of y= -4x -3
Answer:
Step-by-step explanation:
it would be on a graph on -3 going up just by -1 but not hiting it hope this helps
Answer:
-4
Step-by-step explanation:
The equation is conveniently in slope-intercept form.
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
The '-4' is in place of 'm' in the equation. This means that -4 is the slope of the line.
[tex]y=\boxed{m}x+b\rightarrow y=\boxed{-4}x+b[/tex]

The sum of two numbers is 892. One of the numbers is 363. What is the other number?
Answer:
529
Step-by-step explanation:
892=x+363.
We want to get x by itself so we know what it equals.
Because 363 is adding to x we subtract it to the other side.
892-363=529
529=x
So the other number is 529
The other number is 529.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The sum of two numbers is 892.
Let the two unknown numbers be x and y.
Now, x+y=892
One of the numbers is 363.
x+363=892
x=892-363
x=529
Therefore, the other number is 529.

2. What is the slope of a line perpendicular to x + 2y = 5
2/5
2
-1/2
1/2
PLS HELP
Answer:
the perpendicular slope would be 2
Step-by-step explanation:
x+2y=5
2y=5-x
y=(5-x)/2
the slope of the original equation is -1/2
so you would then flip it and multiply by -1.
-1/2 -> -2*-1 -> 2

The endpoints of AB are A(1, 2) and B(7, 8). Find the coordinates of the midpoint
Answer:
The answer is
( 4 , 5)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(1, 2) and B(7, 8)
The midpoint is
[tex]M = ( \frac{1 + 7}{2} , \: \frac{2 + 8}{2} ) \\ = ( \frac{8}{2} \: , \: \frac{10}{2} )[/tex]

Solve for x. (Geometry)
Answer:
x = 7
Step-by-step explanation:
The indicated angles are vertical and congruent, thus
14x + 2 = 13x + 9 ( subtract 13x from both sides )
x + 2 = 9 ( subtract 2 from both sides )
x = 7

For Joe's illness, the doctor gave him a prescription of 28 pills. He needs to take 4 pills the first day, and then 2 pills each day until the prescription runs out. For how many days does he take the 2 pills?
Answer:
12 days.
Step-by-step explanation:
I looked at it this way:
He has to take 4/28 pills the first day, so it's 28-4=24. Then I divided 24 by 2.
In simpler terms:
28-4=24

Dylan has a square piece of metal that measures 10 inches on each side. He cuts the metal along the diagonal, forming two right triangles. What is the length of the hypotenuse of each right triangle to the nearest tenth of an inch? The length of the hypotenuse of each right triangle is _________ inches.
Answer:
14.14 inches
Step-by-step explanation:
We know that the diagonal of a square is [tex]\sqrt{2}a[/tex], where a is the length of the side.
The diagonal of a square is the hypotenuse of this triangle.
That means the hypotenuse will be equal to [tex]\sqrt{2}\cdot10[/tex]
This can be simplified to [tex]\sqrt{200}[/tex], which, rounded to the nearest hundredth is 14.14.
Hope this helped!

If S(0,6) and T(-10,-1) are the endpoints of directed line segment ST. What is the y coordinate of the point that divides the segment into a ratio of 3:4
Answer:
The y coordinate is 3
Step-by-step explanation:
Here, we want to find the y-coordinate of the line that divides the line segment in the given ratio.
To calculate this, we shall be using the internal division formula;
It is as follows;
( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))
In this question;
m = 3 and n = 4
x1 = 0 , y1 = 6
x2 = -10, y2 = -1
Now substituting these values into the equation, we have;
(3(-10) + 4(0)/(3 + 4) , (3(-1) + 4(6)/(3+4))
= -30/7 , (-3 + 24)/7
= -30/7 , 21/7
= -30/7 , 3
slope of (0,1) and (3,0)
Answer:

Step-by-step explanation:
Let the points be A and B
Let A ( 0 , 1 ) be ( x₁ , y₁ ) and B ( 3 , 0 ) be ( x₂ , y₂ )
Finding the slope of the points
[tex] \boxed{ \sf{slope = \frac{y2 - y1}{x2 - x1} }}[/tex]
[tex] \longrightarrow{ \sf{slope = \frac{0 - 1}{ 3 - 0}}} [/tex]

Solve the equation:
1/6(6x−12)=−13−(x−3)
Answer:
x = -4
Step-by-step explanation:
1/6(6x−12)=−13−(x−3)
Distribute
x -2=−13−x+3
Combine like terms
x-2 = -x-10
Add x to each side
x-2+x = -x-10+x
2x-2 = -10
Add 2 to each side
2x-2 +2 = -10+2
2x = -8
Divide by 2
2x/2 = -8/2
x = -4
