As per question,

[tex]2(4x-3)-8=4+2x[/tex]

Opening brackets in left side,

[tex]↪8x - 6 - 8 = 4 + 2x[/tex]

Now bring the common terms together,

[tex]↪8x - 2x = 4 + 6 + 8[/tex]

[tex]↪6x= 18[/tex]

Now divide 18 by 6,

[tex]↪x = \frac{18}{6} [/tex]

[tex]↪x = 3[/tex]

So, Value of x = 3

Write an equation to determine how many pairs of shoes, p, Roger must sell in a day to meet his daily earnings goal:

4.50p + 40 = 112

Find the number of pairs of shoes he must sell to meet his daily earnings goal:

16 pairs of shoes

Step-by-step explanation:

$40 per day

$4.50 per shoe

$112 is earning goal

p = # of shoes he needs to sell, to get to goal

to find p we have to isolate p

4.50p + 40 = 112

subtract 40 from both sides

4.50p = 72

divide both sides by 4.50

p = 16

Roger needs to sell 16 shoes each day in order to achieve his goal of earning $112 each day.

The breeding of the genetics in a deer, in which the parents have both a

N and and a allele results a 0.25 chance of an albino coloring.

Response:

(a) 25%

(b) (0.5·N + 0.5·a)² = 0.25·N·N + 0.25·N·a + 0.25·N·a + 0.25·a·a

(c) The coefficient of the product (offspring) a·a is 0.25 which confirms the response in part (a)

A Punnett square is used for the prediction of the genotypes in a

breeding experiment.

The Punnett square for the possible gene combinations is presented as

follows;

[tex]\begin{tabular}{|c|c|c|c|}&& P2& \\&&N&a\\P1&N&NN normal &Na normal\\&a&Na normal&aa albino\end{array}\right][/tex]

(a) Number of possible gene combination resulting in albino coloring = 1

Number of possible gene combinations = 4

The percentage of the possible gene combination resulting in albino

coloring is therefore;

[tex]Percentage = \dfrac{1}{4} \times 100 = \underline{25\%}[/tex]

(b) The polynomial of each parent gene combination = 0.5·N + 0.5·a

The product that represent the possible gene combinations of an offspring = (0.5·N + 0.5·a)²

(0.5·N + 0.5·a)² = (0.5·N + 0.5·a) × (0.5·N + 0.5·a)

(0.5·N + 0.5·a)×(0.5·N + 0.5·a) = 0.25·N·N + 0.25·N·a + 0.25·N·a + 0.25·a·a

The product is therefore;

(c) From the product of the polynomial, (0.5·N + 0.5·a)², the probability

and therefore, the percentage of the possible gene combinations that

result in albino, a·a is 0.25, which is 25%.

Elena said this is true because the equation 12x+24x+18=36x+24-6 is an infinite solution . If she were to do the equation any further it would end up as each side being equal .

Step-by-step explanation:

if she kept doing it:

12x+28=36x(equation now 36x+18)

24-6=18(equation now 36x+18)

so it would be 36x+18=36x+18 which is an infinite solution because each side equals the other one .
