Answer:
The remainder is 10
Step-by-step explanation:
In division operation
Dividend ÷ divisor = quotient + remainder/divisor
Let us use the remainder Theorem to solve the question
- If the divisor is x + a equate it by zero to find the value of x (x = -a)
- Substitute x in the dividend by this value and calculate it
- The answer of the dividend is the remainder
∵ The dividend is
∵ The divisor is (x + 2)
- Equate the divisor by 0 to find the value of x
∵ x + 2 = 0
- Subtract 2 from both sides
∴ x = -2
Substitute each x in the dividend by -2 and find its value
∵ =
3(16) + 2(-8) - (4) - 4 - 14 =
48 - 16 - 4 - 4 - 14 = 10
∴ The remainder is 10
The answer to the questions
Let's solve for b.
2b−7x=3(b−3)
Step 1: Add -3b to both sides.
2b−7x+−3b=3b−9+−3b
−b−7x=−9
Step 2: Add 7x to both sides.
−b−7x+7x=−9+7x
−b=7x−9
Step 3: Divide both sides by -1.
−b
−1
=
7x−9
−1
b=−7x+9
Answer:
b=−7x+9
