-2/5n = -30 n=

can some one help pleaasee

Answers

Answer 1
Answer: -2/5n=-30n
multiply both sides by -1 sinc I don' like negatives
2/5n=30n
multipl yboth sides by 5/2
1n=150/2n
n=75n
this is obviously false, the only number that would work is 0 since 0 =0 times 75

n=0

What is the measure of o

Answers

Answer:

D

Step-by-step explanation:

We need the formula for arc length (in radians) to solve this problem. The formula is:

s=r \theta

Where

s is the arc length

r is the radius of the circle

\theta is the intercepted angle

In this diagram, we can see that  \theta  is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20

Also, if we look, we see that the radius is 5 cm, so r = 5

Now, we substitute into formula and find \theta:

s=r\theta\n20=5\theta\n\theta=(20)/(5)\n\theta=4

This is given in radians, so \theta is 4 radians

D is the correct answer choice.

Challenger Elementary School has 800 students. Every Wednesday, 12%, percent of the students stay after school for Chess Club. How many students attend Chess Club on Wednesdays?

Answers

96 students attend the Chess Club every Wednesday.

800 is 100% of the population. We simply multiply 12% to the population of 800 to get its value.

800 x 12% = 96 students

To check: divide 96 by 800 to get its percentage.

96 / 800 = 0.12 x 100% = 12%

96 students is equivalent to 12% of 800, the school's total population.

96 students

5x divided by 6 = 20

Answers

We have such equation
(5x)/(6)=20          /*6 (multiply both sides by 6)
5x=20*6
5x=120           /:5   (divide both sides by 5)
x=24 - its the answer

The value of the variable "x" in expression "5x divided by 6 = 20" is 24.

To find the value of the variable "x" in the expression "5x divided by 6 = 20", we use algebraic-techniques.

To separate the variable "x," we multiply both sides of the equation by 6, the denominator of the fraction.

This cancels out the division on the left side, leaving us with 5x on the left side:

⇒ (5x divided by 6) × 6 = 20 × 6,

⇒ (5x/6) × 6 = 20 × 6,

Simplifying the equation:

⇒ 5x = 120

To solve for the variable "x," we divide both sides of equation "5x = 120" by 5:

⇒ (5x) / 5 = 120 / 5,

⇒ x = 24

Therefore, the required value of "x" is 24.
