Explain how we do decimals plus Fractions

You can convert the fractions into a decimal, or a decimal into a fraction. I find that fractions into decimals is easier because with fractions you have the added step of making sure the two numbers have the same denominator.

Also, if you type in the numerator of the fraction divided by the denominator into a calculator, it will automatically give you the decimal. It is a lot harder to convert decimal into fractions if your calculator doesn’t do it.

Answer:

You have to either make the fraction a decimal, or you have the decimal a fraction. Also when making it into a fraction, you should have the same denominator.

What does x equals (x+16)

Brut [27]

Answer:

x+16=4x-5. {being vertically opposite angle}

16+5=4x-x

21=3x

or, 21/3=x

hence, x=7

What is the solution of the equation (x – 5)2 3(x – 5) 9 = 0? use u substitution and the quadratic formula to solve.

Ahat [919]

The value of x in the equation $(x-5)^{2} +3(x-5)+9=0$ is x=(7+3 $\sqrt{3}i$ )/2,

(7-3 $\sqrt{3}i$ )/2.

Given equation $(x-5)^{2} +3(x-5)+9=0$ .

We have to find the solution of the equation.

Equation is solved to find the value of variables. The number of values of the variable depends on the highest power of variables.

let (x-5)=u-------------------1

equation becomes $u^{2} +3u+9=0$

solution of a quadratic formula

x=-b± $\sqrt{b^{2} -4ac}$ /2a

on comparing with general form a=1,b=3, c=9

u=-3± $\sqrt{3^{2} -4*1*9} /2$

=-3± $\sqrt{9-36}/2$

=-3± $3\sqrt{-27}/2$

=-3± $3\sqrt{3} i/2$

$u_{1} =-3$ +3 $\sqrt{3}/2$ , $u_{2}$ =-3-3 $\sqrt{3}/2$

put the values of $u_{1}$ in equation 1

x-5= $u_{1}$

x-5=-3+ $3\sqrt{3} /2$

x=-3+3 $\sqrt{3}i/2+5$

x=7+3 $\sqrt{3} i/2$

put the values of $u_{2}$ in equation2

x-5= $u_{2}$

x-5=-3-3 $\sqrt{3} /2$

x=7-3 $\sqrt{3}/2$

Hence the values of x are 7+3 $\sqrt{3}i/2$ , 7-3 $\sqrt{3}i/2$ .

Heath has 10 pennies in his piggy bank initially. He doubles the number of pennies in his piggy bank each day for five days. wri

vaieri [72.5K]

Answer:

y = 10 * 2^x

y(5) = 10 * 2^5

Day 0 = 10 pennies: Point(0, 10)

Day 1 = 20 pennies: Point(1, 20)

Day 2 = 40 pennies: Point(2, 40)

Day 3 = 80 pennies: Point(3, 80)

Day 4 = 160 pennies: Point(4, 160)

Day 5 = 320 pennies: Point(5, 320)

Step-by-step explanation:

Heath has 10 pennies, so pennies = 10.

He doubles the number of pennies each day, so total pennies = 10 * 2 to the power of # of days.

Using the equation y = 10 * 2^x will give you the answer for any number of days. Since the problem asks for 5 days, you plug in 5 for x. On the graph, this would be a single point (5, 320).

So, plot the 6 points you have and connect a curved line through it. That should be your answer.
