$\dfrac{8-4}{4}+6=\dfrac{4}{4}+6=1+6=7$

$8-\dfrac{8-6}{6-4}=8-\dfrac{2}{2}=8-1=7$

$\dfrac{8+6}{6-4}=\dfrac{14}{2}=7$

you are allowed to work a total of no more than 30 hours each week at your two jobs. Lawn mowing pays $5 per hour and babysittin

timama [110]

Answer:

5X + 8Y >= 300; intersection at (-20, 50)

Step-by-step explanation:

let t = work hours

0 < t < 30

X = time lawn mowing

Y = time babysitting.

X + Y < 30

5X + 8Y >= 300

We could solve...

X < 30 - Y

5(30 - Y) + 8Y >=300

150 - 5Y + 8Y >= 300

3Y >=150

Y >=50

then X < -20

intersection at (-20, 50)

Given that,

NL = 5x, LM = 3x, and NL = 15

L is between M and N.

To find,

The value of x.

Solution,

It is mentioned that, L is between M and N. So,

LM = LN

Put all the values,

3x = 15

⇒ x = 5

I really don't get it can you give me the answer then explain why it is that one please

Ronch [10]

Answer:

$\frac{100}{9}$ is the answer.

Step-by-step explanation:

Well the first thing we would do is simplify all the exponents first inside the parenthesis. So 2^-3 is equal to 1/8. To solve negative exponents you would just divide the number instead of multiply, so 2 divided by 2 divided by 2 is equal to ⅛ or .125

Next would be to do the 2^-9. This would equal 1/512

Now would be to simplify 5^0. Anything to the power of 0 is always one. So now we simplify all the products meaning 7*5*2 and 7*3.

Now we would simplify both fractions.

The picture are pretty much self explanatory. If you have any questions feel free to ask in the comments - Mark

Also when you have the chance please mark me brainliest.
