Answer:

is there a  picture

Step-by-step explanation:

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

Answer:

I need a picture or sum so I can help-

Step-by-step explanation:

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: -25

Step-by-step explanation:

The required integer that shows that 25 feet below the sea level is -25.

Given that,
To determine the in integer that represents 25 feet below sea level.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The sea level is set to equal to 0,
Now height above the seal level comprises of positive sign, and the height below the sea level comprises of negative sign.
So, for  25 feet below sea level,
-25 is the required integer that represents the  25 feet below sea level.

Thus, the required integer that shows that 25 feet below sea level is -25.

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) =

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
