what's supposed to be in the space?

Answers

so first you simplify
24+x=120/3
120/3=40
24+x=40
subtract 24 from both sides
x=16
120/3= 40
40-24=16

Solve this inequality: 3b – 7 < 32 A. b < 8.33
B. b < 39
C. b < 5
D. b < 13

Answers

Answer:

D) b < 13 .

Step-by-step explanation:

Given  :  3b – 7 < 32 .

To find : Solve this inequality.

Solution : We have given 3b – 7 < 32 .

On adding 7 both sides both sides.

3b < 32 + 7.

3b < 39.

On dividing both sides by 3.

b < 13 .

Therefore, D) b < 13 .
It's a lot like solving equations.

3b-7 < 32
Add 7 to each side.
3b < 39
Divide by 3 on each side.
b < 13

A bag has 5 red marbles, 6 blue marbles and 4 black marbles. What is the probability of a blue marble, replacing it, and then picking a black marble?

8/75

4/45

1/9

Answers

There are 15 total marbles in the bag, of which 6 are blue nd 4 are black.

The probability of pulling a blue marble from the full bag is  6/15 .

The probability of pulling a black marble from the full bag is  4/15 .

The probability of both events happening is

             (6/15) x (4/15)  =  24/225 = 8/75

What is 7n+6=4n-9. can someone help plz

Answers

The solution to the given  equation is n=-5.

The given equation is 7n+6=4n-9.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Here, transpose 4n to LHS of the equation and 6 to RHS of the equation, we get

7n-4n=-9-6

3n=-15

n= -15/3

n= -5

Therefore, the solution to the given  equation is n=-5.

Find the area of sector AOB. Enter your answer in terms of a fraction of π and rounded to the nearest tenth.The area of sector AOB is _____ π ≈ _____ mm2.

Answers

40/360 = 1/9

Sector AOB is 1/9 of the total circle.

A = pi x 3^2

A = 9pi

9pi / 9 = 1pi

The area of sector AOB is 1pi = approximately 3.1 mm^2.
