How to solve for 9-2x=35

Mathematics
1 answer:
Irina-Kira [14]3 years ago
6 0
9-2x+35
first you want to get rid of the number. so you subtract 9 on both sides. Think of this as a balance scale, what you do on one side must be done on the other. 
9-2x+35
-9      -9
-2x= 26
you always want to do the opposite, so since this was positive 9  you subtract so the 9 is gone. 
-2x=26
/-2    /-2
you divide each side by -2 and you get
x=-13
since a negative divided by a positive is a negative

For how many integer values of n will the value of the expression 4n + 7 be an integer greater than 1 and less than 200?
Morgarella [4.7K]

Answer:

48

Step-by-step explanation:

We are asked that the value of (4n + 7) will be an integer > 1 and < 200, for how many integer values of n.

So, equating (4n + 7) with 200 we can get the value.

4n + 7 = 200

⇒ 4n = 193

⇒ n = 48.25

Hence, the value of n will be the largest integer less than 48.25.

Therefore, the number of integer values of n will be 48. (Answer)

A square lawn has area 98 ft². A sprinkler placed at the center of the lawn sprays water in a circular pattern as
torisob [31]

The radius of the circle exists approximately 4.95 feet.

<h3>How to estimate the radius of the circle?</h3>

Given the area of the square as A = 98 ft²

The side length of the square choice is equivalent to the diameter of the circle.

First, we must obtain the length of the square.

Area of a square = L^2

98 = L²

L = √98

L = 9.89 ft

Thus the diameter of the circle exists at 9.89 ft

radius = diameter/2

radius = 9.89/2

radius ≈ 4.95 feet

Therefore the radius of the circle exists approximately 4.95 feet.
