He needs to earn ; 77.99-20= 57.99 dollars

so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars

so no of week = 57.99÷ 36= 1.6 weeks

so weeks are in natural no thus it will take him 2 weeks !!

4 weeks because he earns 18 dollars per weekend so 18 multiplied by 4 plus 20 is 92 which gives him enough to get the new skateboard and the reason why it’s not 3 is because 3 multiplied by 18 plus 20 is not enough for the skateboard

(½) (6x + 3) = 7 – (3x + 1)
erastovalidia [21]

\tt Step-by-step~explanation:

To solve for x, we have to remember to isolate the variable.

\tt Step~1:

For 1/2, we can make that 0.5, since their values are equivalent. Our equation:

\tt (0.5)(6x+3)=7-(3x+1)

Let's distribute the 0.5 first.

\tt 0.5*6x=3x\\0.5*3=1.5

\tt Step~2:

Now, let's simplify the right side of the equation. We have to distribute the negative to 3x and 1.

\tt -1*3x=-3x\\-1*1=-1

Then, we simplify the entire expression.

\tt 7-3x-1=-3x+6

\tt Step~3:

Our equation now:

\tt 3x+1.5=-3x+6

Let's add 3x to the right and 3x to the left to simplify the -3x on the right side of the equation.

\tt 3x(+3x)+1.5=-3x (3x)+6\\6x+1.5=6

\tt Step~4:

Let's do the same thing we did in Step 3 to 1.5. Subtract 1.5 on both sides of the equation.

\tt 6x+1.5(-1.5)=6(-1.5)\\6x=4.5

\tt Step~5:

Finally, we divide both sides by 6 to isolate x.

\tt \frac{6x}{6} =x\\\frac{4.5}{6}= 0.75~or~\frac{3}{4}

\large\boxed{\tt Our~final~answer:~x=0.75~(or~\frac{3}{4})}

Why should people be knowledgeable about equations and inequalities?
BartSMP [9]

Answer:

People should be knowledgeable about equations and inequalities because they are often used to solve day to day life problems.

Often times real life problems are modeled using equations and inequalities

Step-by-step explanation:

Inequalities are used often in real life, businesses use inequalities to control inventory, plan production lines, produce pricing models, and for shipping/warehousing goods and materials. Inequalities are used in engineering and production quality assurance.

An equation is the mathematical representation of those two things which are equal, one on each side of an 'equals' sign. Equations are useful to solve our daily life problem.
