17 = 5-x what's the answer
Answers
Answer:
X = - 12.
Step-by-step explanation:
17 = 5 - x
17 = 5 + - x
17 = - x + 5
Then, flip the equation.
-x + 5 = 17
Then subtract 5 from both of the sides.
-x + 5 - 5 = 17 - 5
-x = 12
Then divide
-x/ -1 = 12/1
x = - 12.

Answer:

Multiply
For every 1 mm on the map there are 200 miles of actual distance (third option)
8 cm, 26.8 cm, and 58 cm (last option)
Step-by-step explanation:
Question 1:
An airplane is 180 feet long. Blake makes a scale model of the airplane at 1:60 of its actual size how long is the model?
If the model is scaled down by 1/60, then the model is 60 times smaller than the actual airplane. Set the model size as "x" and so we can write this ratio.
1 / 60 = x / 180
Cross multiply (multiply 60 and x, and 180 and 1)
60x = 180
x = 3 feet
Question 2:
To produce an enlarged or reduced measure you ____ the scale.
In order to find the measure, you multiply it by the scale factor.
Question 3:
A scale on a map is 1 mm: 200 miles
The question tells us that for every 1 mm, there are actually 200 miles. So the answer is the first option, For every 1 mm on the map there are 200 miles of actual distance.
Question 4:
What are the new dimensions if we expand the triangle below by a factor of 4.
If we multiply by the scale factor, 4, we get
2 * 4 = 8
6.7 * 4 = 26.8
14.5 * 4 = 58
Thus, the answer is 8 cm, 26.8 cm, and 58 cm (last option)

Help, The distance between point (2, 2) and point (8, 2) is 6 units on a coordinate plane. Which other pairs of points are also 6 units apart? Select all that apply.
Answers
Step-by-step explanation:
Given - The distance between point (2, 2) and point (8, 2) is 6 units on
a coordinate plane.
To find - Which other pairs of points are also 6 units apart?
Proof -
The distance between two points (x₁, y₁), (x₂, y₂) are 6 if and only if either
( x₂ - x₁ = 6 and y₂ = y₁ )or ( x₂ = x₁ and y₂ - y₁ = 6 ).
If either of the conditions is satisfied , then only we can say that the two points has ha distance of 6 units between them.
Now, As given
Let (x₁, y₁) = ( 2, 2) , (x₂, y₂) = (8, 2)
Check whether the conditions are satisfied or not .
Here x₁ = 2 , x₂ = 8, y₁ = 2, y₂ = 2
Now,
x₂ - x₁ = 8 - 2 = 6 , y₂ - y₁ = 2 - 2 = 0
∴ we get
1st condition is satisfied, So the points have a distance of 6 units between them.
Now,
Let us suppose another point (x₁, y₁) = ( 4, 3) , (x₂, y₂) = (3, 3)
Here x₁ = 4 , x₂ = 3, y₁ = 3, y₂ = 3
Now,
x₂ - x₁ = 4 - 3 = 1 , y₂ - y₁ = 3 - 3 = 0
Here neither of the conditions are satisfied.
So the points are not at a distance of 6 units from each other.

∠V = 33°
∠W = 90°
∠X = 57°
Step-by-step explanation:
In a right triangle, the sum of the acute angles is 90 degrees
(2x+3) + (3x+12) = 90
combine like terms
5x + 15 = 90
5x = 75
x = 15
∠V = 2x+3, x=15
2(15) + 3
30 + 3
33°
∠X = 3x+12, x=15
3(15) + 12
45 + 12
