A group of students auditioned for a theater performance and 3/4 of the group less six students made up the cast of 42 students.

LenKa [72]

Answer:

3/4x-6=42

x=64

Step-by-step explanation:

Let the number of students be x hence 3/4 of this number will be 3/4x

Since the number was 42 if they were 3/4x less six, it means minus six hence

3/4x-6=42

Therefore, the equation will be

3/4x-6=42

Solving the equation

3/4 x=42+6=48

3/4x=48

X=62

1f 3/4 gallon of paint can cover 1/8 of the fence how many gallons will he need to paint the whole fence

lilavasa [31]

Answer:

He will need 6 gallons of painting to paint the whole fence.

Step-by-step explanation:

Since 3/4 gallon of paint covered 1/8 of the fence, we have to multiply 3/4 by 8 in order to find the number of gallons that will paint the whole fence (because 8 x 1/8 = 1)

$\frac{3}{4}$ x $\frac{8}{1}$ = $\frac{24}{4}$ = 6

Hope this helps!

What choices are solutions for equation x^2-3x = -5/4

Kryger [21]

Here's the solution,

=》

${x}^{2} - 3x = - \dfrac{5}{4}$

=》

${x}^{2} - 3x + \dfrac{5}{4} = 0$

now, let's multiply the whole equation with 4

=》

$4 {x}^{2} - 12x + 5 = 0$

=》

$4 {x}^{2} - 10x - 2x + 5= 0$

=》

$2x(2x - 5) - 1(2x - 5) = 0$

=》

$(2x - 1)(2x - 5) = 0$

so,

Case 1. where, 2x - 5 = 0

=》

$x = \dfrac{5}{2}$

case 2. where, 2x - 1 = 0

=》

$x = \dfrac{1}{2}$
