Answer:
x < -6
Step-by-step explanation:
3x - 2 > 5x + 10
first step is to isolate x
3x -2 >5x +10
3x > 5x + 10 + 2
3x -5x > 10 + 2
now that we have 3x and -5x we can combine them
-2x > 10 + 2
now add 10 +2 =12
-2x > 12 (now divide by -2)
x < -6 (when we divide we flip the inequality sign)
<span>-12+2b=12-6b
-12+8b=12
8b=24
b=3</span>
Answer:
option D
Step-by-step explanation:
Jerry solved this equation:

In the first step , she multiplied 3 inside the parenthesis
1. 
In step 2, 3/4 is added on both sides
2. 
In step 3, we take LCD 12
3. 
In step 4, add the fractions
4. 
Here, 3 or 3/1 are same.

In step 5, to remove 3/1 we multiply both sides by 1/3.
Instead of multiplying 1/3 , Jerry made an error by multiplying 3/1


In step 5, he should have multiplied both sides by 1/3
25/4 is the right answer have a good day :)
Answer:
8.9 in.
Step-by-step explanation:
Area of triangle = (1/2) b. h
40 = (1/2) x*x
80 = x^2
square root (80) = x
x=> 8.944.... inch
Rounding off you get 8.9 in.
