Answer:

1  x = 4      y= 2/3  = 1. 66667   see attached and join the lines to create shaded area.

Step-by-step explanation:

2x -3y = 3

16x (64y) = ?

we can multiply the 2x by 8 to find x = 16 and -3y = -24y and 3 = 24

as shown 2nd one.

16x + (64y) =  c

16x -24y = 24    =   64y - 24y = c

40y = c - 24

40y/24 = y

1.66667 = y

y = 1.6667 or  1  2/3

2x -3 (  1 2/3 ) = 3

2x - 5 = 3

2x = 8

x = 4

y = 1. 66657

What is a rational and irrational number?
KIM [24]

Answer:

In mathematics, a rational number is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.

In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.

Step-by-step explanation:

Which equation demonstrates the distributive property?
olga2289 [7]

Answer:

D

Step-by-step explanation:

The distributive property takes place when you distribute what is outside of the parentheses into the parentheses, separating out the equation into easier to develop parts. D does this exactly.

21/2 or 10 1/2
Explanation:
8 3/4 is the same as 35/4

so Darcy harvests 35/4 per 5/6 hours
to figure out how much is harvested in one hour, you divide the amount harvested by the amount of hours taken to harvest it.
35/4 ÷ 5/6 =35/4 × 6/5

35/4 × 6/5 = 7/2 × 3/1 = 21/2

so the answer is 21/2 or 10 1/2

Elinor determined that a triangle with side lengths 6, 10, and 8 does not form a right triangle.62 + 102 = 8236 + 100 = 64136 ≠
weeeeeb [17]

Answer:

Option 3rd is correct

No,

she should have added 6^2 and 8^2 and compared that to 10^2

Step-by-step explanation:

In a right angle triangle, we use Pythagorean theorem.

Pythagorean theorem states that

the sum of the squares of two sides must equal the square of the third side(the side facing the right angle).

i.e,  \text{Hypotenuse side}^2=\text{sum of the square of two side}

Given a triangle with side lengths 6, 10, and 8.

If we square all the given sides, we get;

6^2 = 36,

8^2 = 64

10^2=100

It can be seen that the sum of 36 and 64 is 100

⇒6^2+8^2 = 10^2

which satisfies the Pythagorean theorem.

⇒ The triangle is right-angled with the side lengths 6 units and 8  units forming the right angle and the side length 10 units  being the hypotenuse.

Therefore, her answer is incorrect, she should have added 6^2 and 8^2 and compared that to 10^2
