Answer:

27x+72

Step-by-step explanation:

You have to use the distributive property to simplify the expression. Therefore, you have to multiply both terms inside the parentheses.

1. 9*3x=27x

2. 9*8=72

They could not be added together, as they are not like-terms. So, you just write it down as 27x+72.

What is the rational number equivalent to 1.28 repeating

Anna007 [38]

100*1.2828...= 128.28282828..( so on..)
100x=128.28

then you do 100x - x = 128.2828...- 1.2828..

then we subtract the .282828... part

99x = 127

then divide boths sides by 99 and then x=127/99

G(x)= √x+3 help plsss

const2013 [10]

Answer:

All real values of x such that x ≥-3

Step-by-step explanation:

g(x) = sqrt(x+3)

A sqrt must be greater than or equal to zero

sqrt (x+3) ≥ 0

Square each side

x+3≥ 0

Subtract 3 from each side

x ≥-3

The restrictions on x are x ≥-3

That means the domain is x ≥-3

All real values of x such that x ≥-3

Find the solution of ×\2-1/5=×\3+1/4 please help me with this

ale4655 [162]

Answer:

$x=\frac{27}{10}$

Step-by-step explanation:

Assuming that the beginning equation is $\frac{x}{2} -\frac{1}{5} =\frac{x}{3} +\frac{1}{4}$

First, we should find the common denominator of each of fractions. For all of these denominators, 60 is the smallest common denominator

$\frac{x}{2}(\frac{30}{30}) -\frac{1}{5}(\frac{12}{12}) =\frac{x}{3}(\frac{20}{20}) +\frac{1}{4} (\frac{15}{15}) \\\\\frac{30x}{60}-\frac{12}{60} =\frac{20x}{60}+\frac{15}{60}$
