Answer:
-4.3a + 4.1
Step-by-step explanation:
Well in the given expression,
2.5a - 7 - 6.8a + 11.1
We need to combine like terms,
2.5a + -6.8a = -4.3a
-7 + 11.1 = 4.1
Ans: -4.3a + 4.1
Thus,
the answer is -4.3a + 4.1
Hope this helps :)
The simplification form of given expression is -4.3a + 4.1
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that perform arithmetic operation are called arithmetic operators .
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
The given expression,
⇒ 2.5a - 7 - 6.8a + 11.1
Combine like terms in expression,
⇒ 2.5a - 6.8a + 11.1- 7
Apply the arithmetic operations
⇒ -4.3a + 4.1
Hence, the simplification form of given expression is -4.3a + 4.1
