So its correct

2We multiply 8 by both

So, we have 8x-192

So, no

FIrst, we can do 9 and apply it to both x and -3

So, 9x-27-x+3

So, 8x-24

SO, yes

4

5+3*x = 8x

So, 8x-24

So yes

2. x 2^(x-1)=10. 2x−1=10 2 x - 1 = 10

Step-by-step explanation:

Answer:

1 ) n = -1/4

2 ) x = 3/5

Step-by-step explanation:

First equation:

1/2 = n + 3/4

Step 1 - Flip the equation:

n + 3/4 = 1/2

Step 2 - Subtract 3/4 from both sides:

n + 3/4 - 3/4 = 1/2 - 3/4 =

n = -1/4

Answer: n = -1/4

Second equation:

x - 1/2 = 1/10

Step 1 - Simplify both sides of the equation:

x + -1/2 = 1/10

Step 2 - Add 1/2 to both sides:

x + -1/2 + 1/2 = 1/10 + 1/2

x = 3/5

Answer: x = 3/5

HELP ALGEBRA!!! PROPERTIES

Answers

Answer:

a. addition property of equality

Step-by-step explanation:

2x was added to both sides

Step-by-step explanation:

Step 2: -2x - 3 = x - 18

In order to go to Step 3, we must remove the -2x term from the left. In order to do this, we add 2x on both sides:

-2x - 3 + (2x) = x - 18 + (2x)

=> Step 3: -3 = 3x - 18.

Hence the answer is Addition Property of Equality. (A)

18/0.3=60
60-18=42
42/0.75=56
The bottom diagram is 56 units

Answer:

56

Step-by-step explanation:

80% of sixty is 48 so the 20% is 12.

Example:

12 is 40 percent of the next problem.

12/.4 = 3030*.6 = 18

18 is now 30% of the next strip.

18/.3 = 6060*.7 = 42

42 now is 75% of the last strip

42/.75 = 56

56 is the Answer.
