Order to process an equation with - + / *

Answer:

2x-15 < or = -23

Step-by-step explanation:

Let x be the number.

Twice that number is 2x. 15 less than that is -15.

2x-15 < or = -23

Answer:

z = 42

Step-by-step explanation:

The question can be answered in 2 steps as follows:

Step 1: Calculation of the constant of the variation

The equation for the joint variation can be given as follows:

z = cxy ................... (1)

Where;

z = 60

c = constant = ?

x = 5

y = 6

Substituting the values into equation (1) and solve c, we have:

60 = c * 5 * 6

60 = c * 30

c = 60 / 30

c = 2

Step 2: find z when x = 7 and y = 3

Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:

z = 2 * 7 * 3

z = 42

[tex](4x + 11) + (6x - 13) = 180 \\ 10x + ( - 2) = 180 \\ 10x = 180 + 2 \

Hello!

[tex]\boxed{ \bf d.~0.75g~+~6~≤~30}[/tex]

The variable “g“ represents games, so the coefficient in front of it CANNOT be 6 (since $6 is the cost of the admission and you only have to pay it once).

This automatically eliminates options A and B.

We are now left with C and D.

Since the questions asks for the possible number of games played with $30, we cannot go above it. Therefore, this eliminates option C because that sign is basically telling us that the cost of the admission fee ($6) + the number of games is either greater than or equal to $30. We need it to be LESS than or EQUAL to $30.

Step-by-step explanation:

We are going to express

y in terms of x.

=> 2x + 3y = -4, y = (-4 - 2x)/3.

By Vieta's Formula,

We have SOR = -b/a and POR = c/a.

=> x + y = -7/6, xy = k/6.

When x + y = -7/6,

x + (-4 - 2x)/3 = -7/6.

=> (x - 4)/3 = -7/6

=> (x - 4) = -7/2

=> x = 4 - 7/2

=> x = 0.5.

When xy = k/6,

x(-4 - 2x)/3 = k/6.

Hence k = 6[x(-4 - 2x)/3]

= 2x(-4 - 2x) = 2(0.5)(-4 - 2(0.5)) = -5.

The value of k is -5.

Answer:

[tex]k = -5[/tex]

Step-by-step explanation:

We have the quadratic equation:

[tex]6x^2+7x+k=0[/tex]

Where x and y are the roots of the equation and:

[tex]2x+3y=-4[/tex]

First, using the quadratic formula with a = 6, b = 7, and c = k, we can find the roots to be:

[tex]\displaystyle x=\frac{-(7)\pm\sqrt{(7)^2-4(6)(k)}}{2(6)}[/tex]

Simplify:

[tex]\displaystyle x=\frac{-7\pm\sqrt{49-24k}}{12}[/tex]

So, our two roots are:

[tex]\displaystyle x=\frac{-7+\sqrt{49-24k}}{12}\text{ and } y=\frac{-7-\sqrt{49-24k}}{12}[/tex]

For our first root, we can multiply both sides by 2.

And for our second root, we can multiply both sides by 3.

So, this produces:

[tex]\displaystyle 2x=\frac{-7+\sqrt{49-24k}}{6}\text{ and } 3y=\frac{-7-\sqrt{49-24k}}{4}[/tex]

Since we are given that:

[tex]2x+3y=-4[/tex]

By substitution:

[tex]\displaystyle \Big(\frac{-7+\sqrt{49-24k}}{6}\Big)+\Big(\frac{-7-\sqrt{49-24k}}{4}\Big)=-4[/tex]

Remove the fractions by multiplying both sides by 12:

[tex]\displaystyle (-14+2\sqrt{49-24k})+(-21-3\sqrt{49-24k})=-48[/tex]

Combine like terms:

[tex]-35-\sqrt{49-24k}=-48[/tex]

Adding 35 to both sides produces:

[tex]-\sqrt{49-24k}=-13[/tex]

So:

[tex]\sqrt{49-24k}=13[/tex]

Squaring produces:

[tex]49-24k=169[/tex]

Therefore:

[tex]-24k=120\Rightarrow k=-5[/tex]

Answer:

The ratio of magazines sold to paperbacks sold is 19:12 or 19/12.

Step-by-step explanation:

Given that:

Number of paperbacks sold = 24

Number of hardcovers sold = 6

Number of magazines sold = 38

Number of calendars sold = 5

Ratio of magazines sold to paperbacks sold,

Magazines : Paperbacks

38 : 24

19 : 12

Hence,

The ratio of magazines sold to paperbacks sold is 19:12 or 19/12.

Step-by-step explanation:

as there are 13 diamond cards out of the total 52 cards

Probability that the card is drawn from a deck of cards diamond is equal to [tex]\boldsymbol{\frac{1}{4}}[/tex]

Probability refers to a chance of occurrence of any event.

Value of probability is greater than or equal to zero and less than or equal to one.

Total number of cards in a pack of playing cards [tex]=52[/tex]

Number of diamonds [tex]=13[/tex]

Therefore,

Probability that the card is a diamond [tex]=\frac{13}{52}[/tex]

                                                               [tex]=\frac{1}{4}[/tex]

Answer:

  (x, y) = (1, 2)

Step-by-step explanation:

You can solve this by subtracting the first equation from the second.

  (y) - (y) = (4x -2) -(-3x +5)

  0 = 7x -7 . . . . . .simplify

  0 = x -1 . . . . . . . divide by 7

  1 = x . . . . . . . . . .add 1

Use the first equation to find y:

  y = -3(1) +5

  y = 2

The solution is (x, y) = (1, 2).
