Answer: x= anything less than or equal to 5.

Step-by-step explanation: Because if you plug 5 in the answer for the equation on the right is 60. 60 is less than or equal to 60.

Answer: x ≤ 5

11x + 5 ≤ 60

⇔ 11x ≤ 60 - 5

⇔ 11x ≤ 55

⇔ x ≤ 55/11

⇔ x ≤ 5

Answer:

0.125

Step-by-step explanation:

First, remove the 1/8 by subtracting 1/8 on both sides

-3p = -3/8

Then, isolate the variable by diving each side by -3

p = 0.125

Answer:

Step-by-step explanation:

substitute the value of y in the first equation.

7x-3(5x-4)=20

7x-15x+12=20

-8x=20-12

x=8/-8

x= -1

then you substitute the value of x on the y equation to find y

y=5×-1 -4

y= -5-4

y= -9

Answer:

x = -1, and y = -9

Step-by-step explanation:

This is done by solving one of the two equations for x or y, then substituting it in place of that variable in the other equation.

Since y is already clearly defined in the second equation let's go with that:

[tex]Given\ 7x - 3y = 20,\ and\ y = 5x - 4[/tex]

[tex]7x - 3(5x - 4) = 20[/tex]

[tex]7x - 15x + 12 = 20[/tex]

[tex]7x - 15x = 20 - 12[/tex]

[tex]-8x = 8[/tex]

[tex]x = -1[/tex]

Now we can replace x in the equation for y with -1:

[tex]y = 5(-1) - 4[/tex]

[tex]y = -5 - 4[/tex]

[tex]y = -9[/tex]

To make sure our answers are correct, let's substitute them into the original equations:

[tex](-9) = 5(-1) - 4\\-9 = -5 - 4\\-9 = -9[/tex]

Good, let's test the other equation

[tex]7(-1) - 3(-9) = 20\\-7 - (-27) = 20\\-7 + 27 = 20\\20 = 20[/tex]

So we know that our answer is correct.

Answer:

The answer is "6"

Step-by-step explanation:

[tex]\to x^2 = 3 \times 12 \\\\\to \sqrt{6^2 +3^2} = \sqrt{45} =\sqrt{9} \sqrt{5} = 3\sqrt{5} \\\\\to x= 6[/tex]

Answer:

x= -3/5

Step-by-step explanation:

4x-2y=14

y=12x-1

4x-2(12x-1)=14

4x-24x+2=14

4x-24x=12

-20x=12

×= -12/20

x= -3/5

Answer:

Step-by-step explanation:

let

x = price of a sweatshirt

y = trice of sweatpants

three sweatshirts and two pairs of sweatpants for $85.50

3x + 2y = 85.50

three more sweatshirts and four more pairs of sweatpants for $123

3x + 4y = 123

by solving the system of equations

3x + 2y = 85.50

3x + 4y = 123

we find

x = $16

y = $18.75

Based on the given parameters, Eli’s speed is 5/60 miles per minute

The speed of an object is the rate of change of the distance moved by the object with respect to time

The given parameters are

Distance = 5/6 miles

Time = 10 minutes

The speed is calculated as

Speed = Distance/Time

So, we have

Speed = 5/6 miles/10 minutes

Evaluate

Speed = 5/60 miles per minute

Hence, Eli’s speed is 5/60 miles per minute

Answer:

a. 4x³+13x²+9

Step-by-step explanation:

1. Distribute 4x to every term in the second set of parenthesis to get:

4x³-16x²+12x

2. Distribute 3 to every term in the second set of parenthesis to get:

3x²-12x+9

3. Add/subtract terms with the same variables/degrees:

4x³-16x²+12x+3x²-12x+9

4. The simplified answer is:

4x³+13x²+9

Answer:

4x³ - 13x² + 9

Step-by-step explanation:

(4x + 3)(x² - 4x + 3) =

(4x)(x²) + (4x)( - 4x) + (4x)(3) + 3(x²) + 3( - 4x) + 3(3) =

4x³ - 16x² + 12x + 3x² - 12x + 9 =

= 4x³ - 13x² + 9
