Answer/Step-by-step explanation:
The following steps to solve equation given by join are shown below including the property of numbers applied for each reasons:
4(2a + 3) = -3(a - 1) + 31 - 11a ----› Given
Apply the distributive property to open the parentheses
4*2a + 4*3 = -3*a -3*-1 + 31 - 11a
8a + 12 = -3a + 3 + 31 - 11a ----› Distributive property
Combine like terms together
8a + 12 = 3 + 31 -3a - 11a
8a + 12 = 34 - 14a ---› Combining like terms
Add 14a to both sides
8a + 12 + 14a = 34 - 14a + 14a
22a + 12 = 34 ----› Addition property
Subtract 12 from both sides
22a + 12 - 12 = 34 - 12
22a = 22 ----› subtraction property of equality
Divide both sides by 22
22a/22 = 22/22
a = 1 ----› Division property of Equality
Answer: 
Step-by-step explanation:
Let be "x" the unknown number.
You know that the 25% of the unknown number "x" is 52.
With this information provided in the exercise, you can set up the following proportion:
Now you must solve for "x". The steps to find its value are:
- Multiply both sides of the equation by "x":
- Multiply both sides by 52:
- Divide both sides by 25:
Answer:
x=35
Step-by-step explanation:
The total measure of the degrees in a hexagon is 720 degrees.
1. Write an equation
(4x-5)+117+(3x-3)+3x+6+118+(4x-3)=720
2. Simplify
(4x+3x+3x+4x)+(−5+117+−3+6+118+−3)=720 (Combine Like Terms)
= 14x+230
3. Solve for x
14x+230=720
14x=490
x=35
