Answer:

D, E

Step-by-step explanation:

(4x - 1) ^2 = 11 => (take square roots of both sides)

4x - 1 = +\- sqrt(11) => (Add 1 to both sides)

4x - 1 + 1 = 1 +\-sqrt(11) =>

4x + 0 = 1 +\- sqrt(11) => (Divide both sides by 4)

x = ( 1 +\- sqrt(11) ) /4

Which are choices D and E

How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, the

worty [1.4K]

Answer:

14 groups

Step-by-step explanation:

Given

$Groupings = \frac{1}{2}\ day$

$Duration = 1\ week$

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

$Group = \frac{Duration}{Groupings}$

$Group = \frac{1\ week}{1/2\ days}$

Convert week to days

$Group = \frac{7\ days}{1/2\ days}$

$Group = \frac{7}{1/2}$

$Group = 7 / \frac{1}{2}$

Convert to multiplication

$Group = 7 * \frac{2}{1}$

$Group = \frac{14}{1}$

$Group = 14$

Hence, there are 14 groups

Solve for x 7x/2+5=8 o x=6/7 o x=26/7 o x=21/2 o x=91/2

pshichka [43]

Answer:

x = 6/7

Step-by-step explanation:

7x/2+5=8

Subtract 5 from each side

7x/2+5-5=8-5

7x/2 = 3

Multiply each side by 2/7

2/7 * 7/2x = 3*2/7

x = 6/7
