If you are asking for the square root of 55 then it is 7.6repeating>square root of 55

but if you are asking 55 squared then it is 7.6 repeating<55 squared

Natalie is paid $2 more per hour than Travis when Natalie works for 40 hours and Travis works for 35 hours they are $755 between

daser333 [38]

Answer:

Travis' per hour earnings = $135

Natalie's per hour earnings = $137

Step-by-step explanation:

Given:

Natalie is paid $2 more per hour than Travis

Natalie works for 40 hours

Travis works for 35 hours

The difference between their salaries for their work = $755

To find how much does each earn per hour.

Solution:

Let Travis earn in dollars per hour = $x$

So, for 35 hours of work, his earning in dollars will be = $35\times x = 35x$

Natalie will earn in dollars per hour = $x+2$

So, for 40 hours of work, her earning in dollars will be = $40\times (x+2) = 40(x+2)=40x+80$ [Using distribution]

The difference between the earnings can be given as:

⇒ $40x+80-35x$

Combining like terms

⇒ $5x+80$

The difference = $755

So, we have:

$5x+80=755$

Solving for $x$

Subtracting both sides by 80.

$5x+80-80=755-80$

$5x=675$

Dividing both sides by 5.

$\frac{5x}{5}=\frac{675}{5}$

$x=135$

So, Travis' per hour earnings = $135

Natalie's per hour earnings = $135+2=$ = $137

Help please! detailed would be great!

The goal here is to lose all those denominators so we can solve for y. The common is found by first factoring everything that can be factored 2y-8 factors to 2(y-4) and y^2-16 factors to (y-4)(y+4). The GCF then we will use for cancellation of the denominators is 2(y-4)(y+4). The first term there, when multiplied by that GCF, will cancel with 2(y-4), leaving us with -8(y+4), no more denominator. Going to the next term, when we multiply by the GCF the cancellation happens with the (y+4) term leaving us with no denominator anymore and 2*5(y-4), which simplifies to 10(y-4). Last term. The cancellation happens with the (y+4)(y-4), leaving us with 2(7y+8). Putting all that together looks like this now: -8(y+4)=10(y-4)-[2(7y+8)]. Distributing gives us -8y-32=10y-40-[14y+16] which simplifies to -8y-32=10y-40-14y-16. We will combine like terms to get 0=4y-24. We can factor out the 4 to get 4(y-6)=0. Now of course 4 doesn't equal 0, but y - 6 = 0 and y = 6. Last choice above. There you go!
