Which statement justifies why ∠FBE measures 50°? Given: angles ABD and DBC are complementary
Answer:
If two angles are vertical angles, then they are congruent.
Step-by-step explanation:
If two angles are vertical angles, then they are congruent- this justifies why ∠FBE measures 50°.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
Here, given that,
angles ABD and DBC are complementary
Now, we get,
Hence, If two angles are vertical angles, then they are congruent- this justifies why ∠FBE measures 50°.

A local hamburger shop sold a combined total of 490 hamburgers and cheeseburgers on Saturday. There were 60 fewer cheeseburgers sold than hamburgers.
How many hamburgers were sold on Saturday?
Answer:
315 hamburgurs could be a possible answer
Step-by-step explanation:
Split 490 into an even half, then take away 60, thats for chesburguers. Then subtract that from 490 to find the hambugurs.
6) Maria bought seven boxes. A week later
half of all her boxes were destroyed in a fire.
There are now only 22 boxes left. With
how many did she start?
please helppp
Answer:
37 boxes
Step-by-step explanation:
you should try and write each of the steps into an equation of x. Where x is the boxes she started with
so, she had x boxes, she bought 7 (that's addition) and then half of those boxes (that's division) got destroyed in the fire and she has 22 left (that's your total).
you can write the equation like this:
(x+7)/2 = 22
then, you solve
(x+7) = 44
x = 37
she originally had 37 boxes

The sum of the squares of the two consecutive multiples of 7 is 637. Write the
equation that characterizes this multiples.
Answer:
The first multiple of 7 = 14 or -21
The second multiple of 7 = 21 and -14
Step-by-step explanation:
Let
The first multiple of 7 = 7x
The second multiple of 7 = 7(x+1)
Square of the first multiple = (7x)^2
Square of second multiple = {7(x+1)}^2
Sum
(7x)^2 + 7(x+1)}^2 = 637
49x^2 + 49(x+1)^2 = 637
Divide through by 49
x^2 + (x+1) = 13
Open bracket
x^2 + x^2 + 1 + 2x = 13
Subtract 13 from both sides
x^2 + x^2 + 1 + 2x - 13 = 13 - 13
x^2 + x^2 + 1 + 2x - 13 = 0
2x^2 + 2x - 12 = 0
Divide through by 2
x^2 + x - 6 = 0
Solve the quadratic equation using factorization method
x^2 + 3x - 2x - 6 = 0
x(x+3) - 2(x+3) = 0
(x - 2) (x+3) = 0
x - 2 = 0
x = 2
x+3 = 0
x = -3
Substitute x = 2 or -3 into 7x
When x= 2
7(2) = 14
When x = -3
7(-3) = -21
The first multiple of 7 = 14 or -21
Substitute x = 2 or -3 into 7(x+1)
When x= 2
7(2+1) = 7(3) = 21
When x = -3
7(-3+1) = 7(-2) = -14
The second multiple of 7 = 21 and -14
Whats the factored form of the trinomial 2x^2-26x-60
Answer: Plz mark me brainlest
Step-by-step explanation:
You can factor out a 2, so do that first
2(x^2 - 13x + 30) = 0
Now look at x^2 - 13x + 30. Since you have a positive last term and a negative middle term, then you're looking for something in the form of (x - ?)(x - ?). We have to find two numbers whose product is 30 and whose sum is 13. The numbers must be 10 and 3:
2(x-3)(x-10) = 0

Answer:
y = x + 5
Step-by-step explanation:
Find any two points:
(1, 6)
(2, 7)
Slope = (y2 - y1) / (x2 - x1)
S0:
7 - 6 / 2 - 1
1 / 1
So slope = 1
Equation:
y = mx + b
Plug in the numbers using the x and y of any points:
7 = m * 2 + b
Add m (which is the slope):
7 = 1 * 2 + b
7 = 2 + b
Subtract two from both sides:
5 = b
So our equation is:
y = x + 5
Please let me know if I've done anything wrong!
Answer:
y = x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, 5) ← 2 points on the line
m = [tex]\frac{5-0}{0+5}[/tex] = [tex]\frac{5}{5}[/tex] = 1
The line crosses the y- axis at (0, 5 ) ⇒ c = 5
y = x + 5 ← equation of line
4x+12=−2x
easy points plz solve quick!
Answer:
-2
Step-by-step explanation:
Rearrange:4*x+12-(-2*x)=0
Pull out like factors:6x + 12 = 6 • (x + 2)
Solve:x+2=0
Subtract 2 from both sides of the equation:x = -2
Answer:
x = -2
Step-by-step explanation:
4x + 12 = -2x
4x + 12-12 = -2x - 12
4x = -2x - 12
4x + 2x = -2x - 12 + 2x
6x = -12
x = -2

For question two, the answer is around 6 feet in depth
Step-by-step explanation:
Answer:
1.) 13
2.)either 600 or -600
Step-by-step explanation:
For #1, you would Divide 5 from 65 which equals 13.
For #2, all you practically do is multiply 60 by 10 which equals 600 but since u are going underwater (depth) it would most likely be -600

What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given:
The equation is
1 – (2x + 4) = –4x + 5,
we have to find the correct solution of the equation;
According to given question we have,
Step 1: Open the parenthesis we get,
1 – (2x + 4) = –4x + 5
1-2x-4 = -4x + 5
1-4-2x = -4x +5
-3-2x = -4x + 5
Step 2: Collect like terms we get,
-2x + 4x = 5 + 3
2x = 8
Step 3: divide both sides by 2 we get,
2x/2 = 8/2
x = 4
Hence the correct value of x is 4.

How many square yards of carpet
are needed to cover the floor of
a room that is 18 feet long and
12 feet wide? (1 yd = 3 ft)
The area of the floor required to cover using carpet is equal to 24 square yards .
To calculate the area of the room in square yards,
convert the dimensions from feet to yards and then find the product of the length and width.
1 yard (yd) = 3 feet (ft)
Room length in yards
= 18 feet / 3 feet/yd
= 6 yards
Room width in yards
= 12 feet / 3 feet/yd
= 4 yards
Now, find the area of the room in square yards:
Area = Length × Width
Area = 6 yards × 4 yards = 24 square yards
Therefore, 24 square yards of carpet area required to cover the floor of the room.

Write an equation in slope-intercept form for the line that passes through each pair of points:
(4, -3)(2, 3)
PLS HELP TY
Answer:
y=-3x+9
Step-by-step explanation:
The slope of the line through two points (x1,y1) and (x2,y2) can be found by using the formula below. Don't forget slope is rise over run: subtract the y-values in the numerator to get the rise and subtract the x-values in the denominator (in the same order!) to get the run. Once you know the slope (m), you're halfway there. Now all that's left to find is the y-intercept (b). To find the y-intercept, choose one of the points on the line. It does not matter which point you choose (just pick the one that looks easiest to you). Plug in the values for x and y into the equation and solve for b.

What is the circumference of the following circle?
Vertical line q goes through plane H in the center at point X. Line t comes out of point X. Lines r and s are parallel and are at a right angle to line q. Line p goes through lines r and s. Which line is parallel to line r? line p line q line s line t
Answer:
Option C: Line s
Step-by-step explanation:
Let's refer to plane H as being 2D since we are dealing with lines.
Thus, x-axis would refer to the horizontal axis while y-axis will refer to the vertical axis.
Now, we are told that line q goes through plane H in the center at point X and that Line t is one that comes out from point X.
This means that line q and line t are parallel to each other.
Also, we are told that Lines r and s are parallel and that they're at a right angles to line q.
Since line q and line t are parallel to each other, it means that lines r and s are at right angles to both lines q and t
Thus, it means lines r and s are both perpendicular to lines q and t
Now, we are told that line p goes through r and s.
However, we want to find which line is parallel to line r.
From earlier statement we saw that lines r and s are parallel to each other.
Thus; correct answer is "line s"
Answer:
C
