Answer:

$(10, 0)$

Step-by-step explanation:

Let's try all the options:

$\left \{ {{2x + y = 20} \atop {4x-2y = 40} \right.$

Considering $(10, 0)$ :

$$\left \{ {{2(10) + 0 = 20} \atop {4(10)-2(0) = 40} \right. $\\$

$\left \{ {{20 + 0 = 20} \atop {40-0 = 40} \right.$

$\left \{ {{20= 20} \atop {40 = 40} \right.$

Considering $(0, 10)$ :

$$\left \{ {{2(0) + 10 = 20} \atop {4(0)-2(10) = 40} \right. $\\$

$\left \{ {{0 + 10 = 20} \atop {0-20 = 40} \right.$

$\left \{ {{10= 20} \atop {-20 = 40} \right.$

$\left \{ {{10\neq 20} \atop {-20 \neq 40} \right.$

Considering $(4, 2)$ :

$$\left \{ {{2(4) + 2 = 20} \atop {4(4)-2(2) = 40} \right. $\\$

$\left \{ {{8 + 2 = 20} \atop {8-4 = 40} \right.$

$\left \{ {{10= 20} \atop {4 = 40} \right.$

$\left \{ {{10\neq 20} \atop {4 \neq 40} \right.$

Considering $(10, -10)$ :

$$\left \{ {{2(10) -10 = 20} \atop {4(10)-2(-10) = 40} \right. $\\$

$\left \{ {{20 -10 = 20} \atop {40+20 = 40} \right.$

$\left \{ {{10= 20} \atop {60 = 40} \right.$

$\left \{ {{10\neq 20} \atop {60 \neq 40} \right.$

Answer: See the picture attached.

Step-by-step explanation:

Given the following mixed numbers:

$-2\frac{3}{4}\\\\-4\frac{1}{2}$

You need to convert them to decimal numbers. The steps to do this are shown below:

1. Divide the numerator of the fraction by the denominator.

2. Add the quotient obtained to the whole number part.

Then:

$-2\frac{3}{4}=-(2+0.75)=-(2.75)=-2.75\\\\-4\frac{1}{2}=-(4+0.5)=-(4.5)=-4.5$

Therefore, the point is:

$(-2.75,-4.5)$

Where $-2.75$ is the x-coordinate and $-4.5$ is the y-coordinate.

Knowing this, you can plot it on the coordinate plane, as you can see in the picture attached.

garik1379 [7]

Answer:

20 fluid ounce of tomato paste

Step-by-step explanation:

Given parameters:

Recipe for the sauce;

Fluid ounces of water : Fluid ounces of tomato paste

3: 4

Number of fluid ounces of tomato sauce = 35

Unknown:

Fluid ounces of tomato paste needed = ?

Solution:

Total ratio = 3 + 4 = 7

Fluid ounces of tomato paste = $\frac{fraction of fluid ounces of tomato paste}{total ratio} x total fluid of tomato sauce$

Fluid ounces of tomato paste = $\frac{4}{7}$ x 35 = 20

It will take 20 fluid ounce of tomato paste to make the sauce.
