Answer:

solution for -4 + 3y = 23

3y = 23+4

3y = 27

y = 9

solution for X - y = -7

X = 1

y = 8

Answer: x = 2; y = 9

Step-by-step explanation:

Step one:

given

the diameter of ball 8 inches

radius= 8/2 = 4 in

The volume of the ball

[tex]v=4/3 \pi r^3[/tex]

[tex]v= 4/3*3.142*4^3\\\\v= 4/3*3.142*64\\\\v= 804.35/3\\\\v=268.12 in^3[/tex]

Step two:

we know that

rate= quantity/time

rate= 2.4 in per second

quantity= 268.12

time=?

time= quantity/rate

time= 268.12/2.5

time= 107.2 seconds

Answer:10 adult and 20 children

Step-by-step explanation:

The two inequalities for the given situation are x+y>30 and 15x+9y≤360.

Given that, a hairstylist charges $15 for an adult haircut at nine dollars for a child haircut she wants to earn at least $360.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let the number of adults be x and the number of child be y.

So, x+y>30

Now, 15x+9y≤360

⇒ 3(5x+3y)≤360

⇒ (5x+3y)≤120

From the graph we can see that, two graphs intersecting at (15, 15)

Therefore, the two inequalities for the given situation are x+y>30 and 15x+9y≤360.

The number of all possible combinations of 3 letters can be made from the word 'oranges' = 35

The probability that the three letters will be consonants = 0.114

In this question, we have been given a word 'oranges'

We need to find the number of ways in which the letters of orange can be arranged.

Also, we need to find the probability that these three letters will all be consonants.

The number of letters in the word oranges = 7

So, n = 7

We need combinations of 3 letters.

so, r = 3

The number of all possible combinations of 3 letters would be,

^7C_3 = 7! / (7 - 3)! (3!)

^7C_3 = 35

The number of combinations of 3 letters = 35

We can observe that the consonants in the word 'oranges' are:

r, n, g, s

The number of consonants = 4

The combinations of 3 consonants would be,

^4C_3 = 4! / (4 - 3)! 3!

^4C_3 = 4

The required probability would be,

p = ^4C_3  / ^7C_3

p = 4 / 35

p = 0.114

Therefore, the number of all possible combinations of 3 letters can be made from the word 'oranges' = 35

the probability that the three letters will be consonants = 0.114

w= -1/3

Let's solve your equation step-by-step.

7w+9−4w−4=4

Step 1: Simplify both sides of the equation.

7w+9−4w−4=4

7w+9+−4w+−4=4

(7w+−4w)+(9+−4)=4(Combine Like Terms)

3w+5=4

3w+5=4

Step 2: Subtract 5 from both sides.

3w+5−5=4−5

3w=−1

Step 3: Divide both sides by 3.

3w/3=−1/3

w= −1/3

Answer:

w= −1/3
