12 groups, and each one containing 10. 
Think about it. Which operation could we use?

Multiplication!

12*10 = 120

Dave has 120 rocks. 

(One nice rock collection, Dave)

In a​ week, 17 hens laid 85 eggs. What is the unit rate for eggs per​ hen?
azamat
The unit rate is 5. 

Here's why:
17 is a multiple of 85. To find the unit rate of eggs for 1 hen, you divide 85 divided by 17 which equals 5. So, for every 1 hen there are 5 eggs layed.

I hope this helps:)

What is the measure of the missing angle?<br> 90°<br> 600<br> 7.
RideAnS [48]

Answer:

30°

Step-by-step explanation:

Let the measure of the missing angle be x°

Therefore, by interior angle sum postulate of a triangle:

x + 60° + 90° = 180°

x + 150° = 180°

x = 180° - 150°

x = 30°

Thus the measure of the missing angle is 30°.

|3y-1|&gt;5<br> Solve the absolute value inequalities by making a compound inequality
Fantom [35]

Hi there!

We can begin by solving the inequality using the positive and negative terms:

3y - 1 > 5

Add 1 to both sides:

3y > 6

Divide both sides by 3:

y > 2

Now, solve the negative:

-(3y - 1) > 5

Distribute the -1:

-3y + 1 > 5

Subtract 1 from both sides:

-3y > 4

Divide both sides by -3. REMEMBER to flip the sign.

y < -4/3

'y' has to be LESS than -4/3 and greater than 2, so:

y < -4/3, y > 2
