Answer:
C. x = 7
Step-by-step explanation:
All angles of a square add up to 360° and there are 4 angles in every square. Since all angles of a square are 360/4 = 90, Then 12x + 6 = 90.
12x + 6 - 6 = 90 - 6
12x = 84
12x/12 = 84/12
x = 7
Answer:
The answer here is 3.
Step-by-step explanation:
Since 7 of the marbles are yellow and 13 of them are green, you would first add these numbers together to find the number of marbles that are not green. After doing this you will find that 20 of the marbles aren't green. Since there are 23 marbles, and 20 of them aren't green, you would subtract these two numbers to find that the number of green marbles is three.
When dividing fractions, you flip the second fraction and multiply
Next, we multiply:
