Answer:

Weathering

Step-by-step explanation:

Weathering is the physical and chemical breakdown of rock at the earth's surface. The physical breakdown of rock involves breaking rock down into smaller pieces through mechanical weathering processes. These processes include abrasion, frost wedging, pressure release (unloading), and organic activity.

The swimming team has 84 members. The number of boys on the team is six more than twice the number of girls. How many boys and g

Kamila [148]

Answer:

the number of boys and girls on a team is 58 and 26 respectively

Step-by-step explanation:

Given that

Total members in swimming team is 84

Let us assume the number of girls be x

so, the number of boys would be

y = 2x + 6

Now the equation is

x + y = 84

x + 2x + 6 = 84

3x = 78

x = 26

And, y = 2 × 26 + 6

= 52 + 6

= 58

Hence, the number of boys and girls on a team is 58 and 26 respectively

How many real-number solutions does the equation have?

Nataly_w [17]

Answer:

Option b. Two solutions

Step-by-step explanation:

In order to find how many real number solutions the equation has we have to solve it

Given equation: -4x² + 10x + 6 = 0

taking 2 common from the equation

2(-2x² + 5x + 3) = 0

-2x² + 5x + 3 = 0

taking minus sign common from the above equation

2x² - 5x - 3 = 0

We will solve this equation by factorization in such a way that the sum of two factors is equal to -5x and the product is -6x²

2x² - 6x + x - 3 = 0

taking common above

2x(x-3) + 1(x-3) = 0

taking (x-3) common

(2x+1)(x-3) = 0

2x + 1 = 0

2x = -1

x = $\frac{-1}{2}$

x - 3 = 0; x = 3

the solutions are

$x=\frac{-1}{2},3$

Both values are real numbers, therefore correct option is b
