The math does not follow the rules of math; Of course can say 1 + 4 = 52 + 5 = 123 etc, etc. However the rules of math state 1 + 4 does not equal 52 + 5 = 57. The logic of the math breaks down immediately in the first equation. There is no logic in absolute mathematics to this equation. There is no answer.

A) y=x+7
B) y=200/4=50
C) y=x+7 and we know that y=50 so we have 50 = x+7 which can be changed to x=50-7=43

Rasek [7]

Answer:

a. 1.23

b. 0.23

c. 7.96

Step-by-step explanation:

Use laws of logarithms:

log(a*b) = log(a) + log(b)

log(a/b) = log(a) - log(b)

log(a^b) = b*log(a)

log_k(k) = 1

a. log_a(15) = log_a(3*5) = log_a(3) + log_a(5) = 0.50 + 0.73 = 1.23

b. log_a(5/3) = log_a(5) - log_a(3) = 0.73 - 0.50 = 0.23

c. log_a(8*a^7) = log_a(8) + log_a(a^7) = log_a(2^3) + log_a(a^7)

= 3log_a(2) + 7log_a(a) = 3(0.32) + 7(1) = 7.96

QUESTION 1

We want to simplify,

$5x + 10y + 7x - 4y$

We regroup to obtain,

$5x + 7x + 10y - 4y$

We simplify to obtain,

$12x + 6y$

QUESTION 2

We want to solve

$5x - 14 = - 34$

We group like terms to obtain,

$5x = - 34 + 14$
Simplify

$5x = - 20$

We divide both sides by 5 to get,

$x = \frac{ - 20}{4}$

This gives us,

$x = - 5$

QUESTION 3

We want to simplify

$2(p + 8) = 26$

We divide both sides by 2 to obtain,

$\frac{2(p + 8)}{2} = \frac{26}{2}$

$p + 8 = 13$

We group like terms to obtain,

$p = 13 - 8$

$p = 5$

QUESTION 5

The inequality given to Bob was

$- 2x + 5 < \: 17$

He added the additive inverse of 5 to both sides to obtain,

$- 2x + 5 - 5 < \: 17 - 5$

He gets

$- 2x < \: 12$

He needs to divide both sides by -2 and reverse the inequality sign to obtain,

$x > \: - 6$

The error is that, he forgot to reverse the inequality sign.
