How do you solve equations with decimals and parentheses?
How do you solve equations with decimals and parentheses?
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.

Therefore, the solution to the equation is 7.9.
I have an equation like this 0.7 ( x + 1.2) = 2.8
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.
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.
And this one
82.78 (p + 11.892) = 72.8464
82.78 (p + 11.892) = 72.8464
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.
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.
It's wrong and no matter what I do I can't get it right
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.
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.
