Answer:

Step-by-step explanation:

hello

$2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4 \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by \ \ 2\\$

so the solution is 2

$5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4 \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by \ \ 5$

so the solution is 4/5

hope this helps

Divide:5.52 x 1031.2 x 105Write your answer in scientific notation. For example, you'd enter 2.3*10^4 for 2.3 x 104

IrinaK [193]

The question can be solved as follows:

$\frac{5.52\times10^3}{1.2\times10^5}=\frac{5.52}{1.2}\times10^{-2}=4.6\times10^{-2}$

Hence the value of the given expression in scientific notation is expressed as:

$\frac{5.52\times10^3}{1.2\times10^5}=4.6\times10^{-2}$

The seventh grade class is putting on a variety to raise money . It cost $700 to rent the banquet hall that they are going to us

liberstina [14]

The class needs to sell at least 20 tickets

Let x be the number of tickets that need to be sold in order to add up to $1000

Using the equation $700+$15x>=$1000

Subtract 700 from both sides and then divide each side by 15 to get 20.
