Can someone help please?
bearhunter [10]

Answer:

1) 2<x<10 (the first choice)

2) 17<u><</u>x<40 (the first choice)

3) x<u><</u>-1 or x<u>></u>2 (the second choice)

Step-by-step explanation:

1) 2<x<10...this is another way of representing x<10 and x>2 in an "and" inequality. If you look at 2<x<10 from left to right, it says 2 is less than x and x is less than 10.

2) 17<u><</u>x<40...this represents x<u>></u>17 and x<40 in an "and" inequality as well. If you look at 17<u><</u>x<40, it reads 17 is less than or equal to x and x is less than 40.

3) x<u><</u>-1 or x<u>></u>2...the signs are greater than or equal to because the dots are closed on the number line. Also, this is not an "and" inequality. This is actually an "or" inequality. You can mainly tell because the lines are shaded opposite ways and do not intersect.

I hope this helped!! Good luck on your assignment and have a wonderful day :3

Beatrice makes a jar of dry soup mix. The ingredients are: 1 ¾ cups of uncooked rice
Lapatulllka [165]

Answer:

5 cups of soup mix

Step-by-step explanation:

3. You can make the addition easier by finding a common denominator 12.

7/4 + 1/2 + 5/3 + 1/3 + 1/4 + 1/2  --> 21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12

To do this you need to multiply every numerator and denominator by the same number until the denominator is equal to 12. When it is 12 you can add up all the fractions to get 5.

I hope this helps!

Simplify the problem ( 3 over 5 to the power of negative 3
sweet-ann [11.9K]

(\frac{3}{5})^-^3

First you had to used their apply exponent rule.

And it gave us ⇒ (\frac{5}{3})^3

Then apply exponent rule again.

And it gave us ⇒ \frac{5^3}{3^3}

125=5^3=5*5*5=125

=\frac{125}{3^3}

27=3^3=3*3*3=27

=\frac{125}{27}

Final answer: ⇒ \boxed{125/27}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
