60 x .10 = 6
60 + 6 = $66
Answer:
D
12²
Step-by-step explanation:
Given in the question, an integer = 144
To find the exponential form 144 we will do factorisation
The prime factorisation of 144 is
2 × 2 × 2 × 2 × 3 × 3
So the exponential form is 2
× 3²
The other way is
√144 = 12
which means
12² = 144

Answer:
1a. x=1/2 1b. x= 4
Step-by-step explanation:
1a. 30x= 16- 2x
(add 2x to both sides)
32x= 16
(divide both sides by 16)
x= 1/2
1b. 2(3x-5)=2x+6
(distribute the 2)
6x-10=2x+6
(add 10 to both sides)
6x=2x + 16
(subtract 2x from both sides)
4x= 16
(divide both sides by 4)
x=4
