disa [49]

The answer is:  "6.75 ft." .
______________________________________________
Explanation:
_____________________________________________
2 / 3 = (4.5) / x ; Solve for "x" ;

     2x = (3)(4.5) ;

Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________________________
    2x / 2 = [3*(4.5)] / 2 ;

    to get: x = (13.5)/2 = 6.75 ft. This is already rounded to the
                                                       nearest hundredth.

Linda scored 3 points more than twice Lisa's points on a driver's ed test. Lisa scored p points. Which equation can be used to f

n200080 [17]

m = 2p + 3

I'm going to say that is correct because you're trying to find m, which is Linda's score. And her score is 2 times + 3 more than Lisa's.

Hope this helps!!(:

What is the highest fraction here -3/25, -7 / 20, -27 / 50, -13 / 20, 16 / 25, 53 / 100, -1 / 3

galina1969 [7]

16/25 is the highest, because if you multiply it by four you get 64/100, and the rest of the fractions are negative.

<h3>given;</h3>

5,870,000,000,000 miles.

The distance light travels in 100 years.

<h3>solution:</h3>

The distance of the light travels in 100 years is:

5,870,000,000,000 × 100 miles.

= 587,000,000,000,000 miles

Simplify the expression

Molodets [167]

Answer:

8x^8/3 y^4 - The first option

Step-by-step explanation:

The first thing we need to do is the exponent outside the bracket and leave the 8 till last, because exponents always come before multiplying coefficients. When an term with an exponent is multiplied by another exponent outside a bracket, the exponents of both terms are multiplied by the exponent outside the bracket.

This means that the expression is now:

8(x^2*4/3 y^3*4/3)

First we can so the x term. The x term already has an exponent of 2, so the 2 is multiplied by the 4/3 exponent outside the bracket. 2*4/3 = 8/3, so the x term is now: x^8/3

The same happens to the y term: 3*4/3 simplifies to 4, so the y term is now y^4.

So now our expression is:

8(x^8/3 y^4)

Now the 8 outside the bracket simply multiplies on to the whole term so we finish with:

8x^8/3 y^4 - The first option.

Hope this helped!
