Answer:
x=√y+4 or x=−√y+4
Step-by-step explanation:
Step 1: Add 4 to both sides.
x2−4+4=y+4
x2=y+4
Step 2: Take square root.
x=√y+4 or x=−√y+4
3(6x+1) I’m not sure but probably this could be right
Answer:

Step-by-step explanation:
When two dice are rolled, the sample space is

In total, 36 outcomes
First, find the probability that the sum is 10 or greater:
All favorable outcomes
10: 
11: 
12: 
In total, 6 outcomes.
The probability that the sum is 10 or greater is

Use the complement rule to find that the probability that the sum of the dice is less than 10:

Check the picture below.
∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.
∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.
∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.
Answer:
So we have this equation:
r/10 + 4 = 5
FIrst, we can substract 4 in both sides
r/10 + 4 - 4 = 5 - 4
r/10 = 1
Now, we can multiply both sides per 10:
r/10 * 10 = 1 * 10
r = 10
And we know that r = 10, and that's the result of the equation.
