Answer:
x = 20
Step-by-step explanation:
The two angles are verticals angles and vertical angles are equal
7x -99 = 2x+1
Subtract 2x from each side
7x-99-2x =2x+1-2x
5x-99 =1
Add 99 to each side
5x-99+99 = 1+99
5x =100
Divide each side by 5
5x/5 =100/5
x = 20
Answer:
<h2>
X = 4.5</h2>
Step-by-step explanation:
So we have two equations.
y=35x+40
y=40x+17.5
We want to find the coordinates in which they intersect.
BUT They never intersect, They are parallel to each other leaving us with a
NO SOLUTION
When you are trying to solve for x you want to get rid of the y's and simply put on your paper: 35x+40 = 40x+17.5
Then you distribute, in which I am not going to show because that too many steps lol. But you'll get:
x=4.5
The answer is 8.
2^-3 is 0.125.
Then 0.125 is divided by 1, equals 8.
Answer:
36 grams mass will stretch the spring 12 centimeters.
Step-by-step explanation:
Here, Distance of the spring ∝ The Mass attached
or D = k M ( for some arbitrary constant k )
Now, for m = 15 g, D = 5 centimeters
So, here 5 = k(15)
or,
⇒ For D= 12 cm , D = k M
⇒
or, M = 36 grams
Hence, 36 grams mass will stretch the spring 12 centimeters.
