When elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that

make it.

When ever you combine different elements the chemical properties change because elements are different , unless you combine the exact same elements.

6. The height of a triangle is 2 units more than the base. The area of the triangle is 10 square units. Find

Harrizon [31]

Answer:

4.24

Step-by-step explanation:

First, let's set up the equation: $\frac{2+x^2}{2}=10$

Next, clear the fraction by multiplying both sides by 2: $2*(\frac{2+x^2}{2}=10)=2+x^2=20$

Then, subtract 2 from both sides: $x^2=18$

Finally, take a square root of both sides and round: $\sqrt{x^2=18} =$ (Rounded to the nearest hundredth) 4.24

Tammy has 4 times as many books as Willy . Willy has 180 fewer books than Tammy . How many books does Willy have ?

enyata [817]

Answer:

60 books

Step-by-step explanation:

let the number of books Willy has be x , then

Tammy has 4x books

Willy has 180 fewer books , that is Tammy has 180 more than Willy , so

4x = x + 180 ( subtract x from both sides )

3x = 180 ( divide both sides by 3 )

x = 60

Thus

Willy has 60 books andTammy has 4 × 60 = 240 books

which is 180 more than Willy

ABCD is a parallelogram. Segment AC = 4x + 10. Find the value of x and y.

valkas [14]

Answer:

The values of x and y in the diagonals of the parallelogram are x=0 and y=5

Step-by-step explanation:

Given that ABCD is a parallelogram

And segment AC=4x+10

From the figure we have the diagonals AC=3x+y and BD=2x+y

By the property of parallelogram the diagonals are congruent

∴ we can equate the diagonals AC=BD

That is 3x+y=2x+y

3x+y-(2x+y)=2x+y-(2x+y)

3x+y-2x-y=2x+y-2x-y

x+0=0 ( by adding the like terms )

∴ x=0

Given that segment AC=4x+10

Substitute x=0 we have AC=4(0)+10

=0+10

=10

∴ AC=10

Now (3x+y)+(2x+y)=10

5x+2y=10

Substitute x=0, 5(0)+2y=10

2y=10

$y=\frac{10}{2}$

∴ y=5

∴ the values of x and y are x=0 and y=5
