Answer:
If the directions say write an equation: 2n + 5 =25
If the directions say also to solve the equation and find the number: 10
Step-by-step explanation:
"The sum" means we're using adding. So what things are we adding together? The question says "twice a number" and 5. Well we've got the 5. And "twice" means two times. And "a number" means we don't know the number yet, so we choose a variable, like n.
"Twice a number" can be written 2n.
So far we have:
2n + 5 is 25
We use = for the "is" in this sentence.
2n + 5 = 25
Now we can solve it.
Subtract 5 from both sides.
2n = 20
Divide by 2 on both sides.
2n/2 = 20/2
n = 10
The number is 10.

Classify the following triangle as acute, obtuse, or right.
O A. Acute
O B. Obtuse
O C. Right
O D. None of these
Answer:
It is an obtuse angle so correct
The given triangle is an obtuse angle triangle.
The correct option is (B).
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data in the diagram:
We are given a triangle and all the angles of the triangle are also given.
We have to find out the type of the triangle.
If all angles of a triangle are less than 90°, then it's an acute angle triangle.
If any angle of the triangle is greater than 90°, then it's an obtuse angle triangle.
If any angle of the triangle is equal to 90°, then it's a right angle triangle.
For the given triangle:
30° < 90°
24° < 90°
126° > 90°
The given triangle is an obtuse angle triangle.
Hence, the given triangle is an obtuse angle triangle.

What is the slope of the line passing through(-7, 8) (-8, 8) is?
Answer:
Step-by-step explanation:
(-7, 8) (-8, 8)
(y2 - y1) / (x2 - x1)
(8 - 8) / (-8 + 7)
0 / -1
the slope is 0
you could also see this because the y value doesn't change
if the y value doesn't change the slope is 0, if the x value doesn't change the slope is undefined
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 7, 8 ) and (x₂, y₂ ) = (- 8, 8 )
m = [tex]\frac{8-8}{-8-(-7)}[/tex] = [tex]\frac{0}{-8+7}[/tex] = [tex]\frac{0}{-1}[/tex] = 0

A scale drawing of a rectangular park had a scale of 1 cm = 100 m. What is the actual perimeter of the park in meters?
10.1 and 8.8
Answer:
3780 m
Step-by-step explanation:
First, we find the perimeter of the scale drawing.
perimeter = 2(L + W)
perimeter = 2(10.1 cm + 8.8 cm)
perimeter = 2(18.9 cm)
perimeter = 37.8 cm
Now that we have the perimeter of the drawing, we use the scale to find the real perimeter.
1 cm (drawing) = 100 m (real)
37.8 cm × 100 m/cm = 3780 m
Answer: 3780 m

Juliet needs to rewrite 3 (x 2) = 6 y in slope-intercept form so she can easily graph it. Which step would be correct to start the process? She could combine the x and 2 to get 3 (2 x) = 6 y. She could divide both sides by 3 to get x 2 = 2 y. She could distribute the 3 to get 3 x 2 = 6 y. She could subtract the 6y to get Negative 6 y = 3 (x 2).
The step that would be correct to start the process is she could distribute the 3 to get 3x+2=6y
Note that the standard equation of a line in slope-intercept form is expressed as y = mx + b
m is the slopeb is the y-interceptGiven the function 3(x+2)=6y, for Juliet to write in slope-intercept form, the best approach is to first divide both equations by 6 as shown:
[tex]3(x+2)=6y \\\frac{3(x+2)}{6} =\frac{6y}{6} \\\frac{x+2}{6}=y[/tex]
Swap sides
[tex]y=\frac{x+2}{6}\\y=\frac{1}{6}x +\frac{1}{3}[/tex]
She could as well distribute the 3 over x + 2 to have:
3(x + 2) = 6y
3x + 3(2) = 6y
3x + 6 = 6y
Hence based on the option, the step that would be correct to start the process is she could distribute the 3 to get 3x+2=6y
