Simplify:

-30x^9/10x^17

Answers

Answer 1

Answer:

-3/x^8

Step-by-step explanation:

First, we simplify -30/10 which will be -3.

Next, we simplify x^9/x^17 which will be x^-8, since when dividing exponents, you subtract them. Sorry if this sounds confusing, but if this helps you better understand it, then here you go: I mean that y^n/y^z = y^(n-z).

x^-8 = 1/(x^8), and to find our answer, we multiply this by -3 to get an answer of:

-3/x^8

A cookie recipe calls for ¾ cup of sugar. You have the
following measuring cups: 1 cup, ½ cup, ⅓ cup, ¼ cup, ⅛ cup, and a tablespoon (which is 1/16 cup).
Suppose your ¼ cup is missing. How would you measure ¾ cups of sugar using at least two of the other measuring cups? Show your work.

Answers

Answer:

1/2 cup and 2 1/8 of a cup

Step-by-step explanation:

1/8 +1/8=1/4

1/2 is equaled to 2/4

so 2/4+1/4=3/4

You need 3/4 cup of sugar and your 1/4 is missing
First use the 1/2 cup which is equal to 2/4
Now a tablespoon is 1/16 of a cup, so use 4 table spoons, which is 1/4 of a cup
You finally have 3/4 cups of sugar because you have 1/2 cups of sugar and 4/6 cup of sugar

Answer:

[tex]7\frac{1}{3}[/tex]

Step-by-step explanation:

So for this problem, we want to solve for x

75x + 50 = 600

First, we isolate x by subtracting 50 from both sides.

75x + 50 - 50 = 600 - 50

75x = 550

Then we divide both sides by 75 to find x

75*x/75=550/75
