Question

82.78 ÷ 82.78
And
82.78 ÷ 11.892

Answer 1

1 +6.96

Answer 2

I think I did that wrong...
How do you solve equations with decimals and parentheses?

Answer 3

I have an equation like this 0.7 ( x + 1.2) = 2.8

Answer 4

And this one
82.78 (p + 11.892) = 72.8464

Answer 5

It's wrong and no matter what I do I can't get it right

Answer 6

82.78 ÷ 82.78 equals 1.
82.78 ÷ 11.892 equals 6.96.

Answer 7

1 + 6.96 equals 7.96.

Answer 8

To solve equations with decimals and parentheses, you can follow the following steps:

1. Simplify any expressions within parentheses first.
2. Perform any addition or subtraction operations.
3. Finally, perform any multiplication or division operations.

For example, if you have the equation:

2.5 * (3.8 + 1.2) - 4.6

1. Simplify the expression within the parentheses first: (3.8 + 1.2) equals 5.
2. Multiply 2.5 by 5: 2.5 * 5 equals 12.5.
3. Finally, subtract 4.6 from 12.5: 12.5 - 4.6 equals 7.9.

Therefore, the solution to the equation is 7.9.

Answer 9

To solve the equation 0.7 (x + 1.2) = 2.8, you can follow these steps:

1. Distribute the 0.7 to the terms inside the parentheses:
0.7 * x + 0.7 * 1.2 = 2.8.

2. Simplify the multiplication:
0.7x + 0.84 = 2.8.

3. Subtract 0.84 from both sides to isolate the term with x:
0.7x = 2.8 - 0.84.

4. Simplify the subtraction:
0.7x = 1.96.

5. Divide both sides of the equation by 0.7 to solve for x:
x = 1.96 / 0.7.

6. Evaluate the division:
x ≈ 2.8.

Therefore, the solution to the equation is x ≈ 2.8.

Answer 10

To solve the equation 82.78 (p + 11.892) = 72.8464, you can follow these steps:

1. Distribute the 82.78 to the terms inside the parentheses:
82.78p + 82.78 * 11.892 = 72.8464.

2. Simplify the multiplication:
82.78p + 981.205536 = 72.8464.

3. Subtract 981.205536 from both sides to isolate the term with p:
82.78p = 72.8464 - 981.205536.

4. Simplify the subtraction:
82.78p = -908.359136.

5. Divide both sides of the equation by 82.78 to solve for p:
p = -908.359136 / 82.78.

6. Evaluate the division:
p ≈ -10.9647.

Therefore, the solution to the equation is p ≈ -10.9647.

Answer 11

Apologies for the previous incorrect solution. Let's solve the equation step by step:

82.78 (p + 11.892) = 72.8464

1. Distribute the 82.78 to the terms inside the parentheses:
82.78p + 82.78 * 11.892 = 72.8464

2. Simplify the multiplication:
82.78p + 982.94816 = 72.8464

3. Subtract 982.94816 from both sides:
82.78p = 72.8464 - 982.94816

4. Simplify the subtraction:
82.78p = -910.10176

5. Divide both sides of the equation by 82.78 to solve for p:
p = -910.10176 / 82.78

6. Evaluate the division:
p ≈ -10.981

Therefore, the correct solution to the equation is p ≈ -10.981.
