Answer:
-4 = y
Step-by-step explanation:
3(6+5y)=2(-5+4y)
18 + 15y = -10 + 8y
+10 +10
28 + 15y = 8y
- 15y -15y
28 = - 7y
28/-7 = -4
-7y/-7 = y
If you simplify the expression, it comes out to just 14.
Answer:
4
Step-by-step explanation:
1. Find the Mean
(8+12+15+17+18)/5=14
2.For each number, subtract the Mean and square the result.
(8-14)^2=36
(12-14)^2=4
(15-14)^2=1
(17-14)^2=9
(18-14)^2=16
3. Find the Mean of those squared differences.
(36+4+1+9+16)/5=13.2
4.Take the square root of that and this is what you want.
square root of 12.7 = 3.6 (round up to 4)
