Answer:

160 children

Step-by-step explanation:

We can get this solution by working backwards in the equation.

First, we can treat the total number of strudents who play tennis as 't'. Giving us the equation: 8 = .25(t) . Solving this we get that there are 32 tennis players.

Next, we have to derive the total number of children in the sports club. Setting up 'x' as the total number of children, I get the equation 32 = .2(x) . Which leads us to the solution of 160 children in the sports club.

What is the factorization of the trinomial below -x^2+x+42

aksik [14]

For the given trinomial

$a=-1, b=1 ,c=42$

We need to multiply a by c
$-1 \times 42 = - 42$

We split the middle term with these two factors
$7,-6$
To obtain,

$- {x}^{2} + 7x -6x + 42$
We now factor

$- {x}^{2} + x + 42 \: = x( - x + 7) + 6( - x + 7)$
This implies

$- {x}^{2} + x + 42: = (x + 6)(7 - x)$

How many soultions does 5(x-3)+6=5x-9

olya-2409 [2.1K]

5(x - 3) + 6 = 5x - 9 has no solution

Solution:

We have to find the number of solutions for the given equation

Given equation is:

5(x - 3) + 6 = 5x - 9

Multiply the terms inside with bracket with constant outside the bracket

5x - 15 + 6 = 5x - 9

Add the constants in left hand side of equation

5x - 9 = 5x - 9

If the coefficients are the same on both sides, then the sides will not equal, therefore no solutions will occur.

Here, 5x - 9 = 5x - 9

The coefficients are same in both sides of equation

Therefore, the equation has no solution
