For this case we have the following system of two equations with two unknowns:

$y-2x = -2\\y-x = 1$

When solving the system graphically, the solution will be given by the intersection of the lines.

If we look at the attached image, the solution of the system is given by:

$(x, y) = (3,4)$

A triangular prism container is full of water of 428 cubic cm. The water is 10 cm deep, what is the base area of the container?

Hatshy [7]

<h3>The base area of triangular prism container is 42.8 cubic centimeter</h3>

Solution:

The volume of triangular prism is given as:

$v = base\ area \times height$

Given that,

A triangular prism container is full of water of 428 cubic cm

The water is 10 cm deep

Therefore,

v = 428 cubic cm

h = 10 cm

Substituting the values we get,

$428 = base\ area \times 10\\\\base\ area = \frac{428}{10}\\\\base\ area = 42.8\ cm^2$

Thus the base area of triangular prism container is 42.8 cubic centimeter

Select all the expressions with a product less than 2/3.

Monica [59]

The expressions with a product less than 2/3 are:

2/3 × 2/3 and 5/6 × 2/3 ⇒ 2nd and 4th

Step-by-step explanation:

Let us revise some fact about the product of two numbers

If x is multiplied by y where y > 1, then the product is greater than x (Ex: if x is 3/4 and y is 2, then xy = (3/4)(2) = 3/2 which is greater than 3/4)
If x is multiplied by y where 0 < y < 1, then the product is less than x (Ex: if x = 2/5 and y = 1/3, then xy = (2/5)(1/3) = 2/15 which is less than 2/5)

We need to select all the expressions with a product less than 2/3

∵ 4 and 1/8 × 2/3

- 4 and 1/8 means mixed number $4\frac{1}{8}$

∵ $4\frac{1}{8}$ > 1

- That means the product of it and 2/3 will be greater than 2/3

as the first fact above

∴ $4\frac{1}{8}$ × $\frac{2}{3}$ > $\frac{2}{3}$

∵ $\frac{2}{3}$ × $\frac{2}{3}$

∵ $\frac{2}{3}$ is between 0 and 1

- That means the product of it and 2/3 will be less than 2/3

as the second fact above

∴ $\frac{2}{3}$ × $\frac{2}{3}$ < $\frac{2}{3}$

∵ $\frac{2}{3}$ × 2

∵ 2 > 1

- That means the product of it and 2/3 will be greater than 2/3

as the first fact above

∴ $\frac{2}{3}$ × 2 > $\frac{2}{3}$

∵ $\frac{5}{6}$ × $\frac{2}{3}$

∵ $\frac{5}{6}$ is between 0 and 1

- That means the product of it and 2/3 will be less than 2/3

as the second fact above

∴ $\frac{5}{6}$ × $\frac{2}{3}$ < $\frac{2}{3}$

The expressions with a product less than 2/3 are:

2/3 × 2/3 and 5/6 × 2/3
