Answer:
6ab.
Step-by-step explanation:
3 x a x 2 x b
= 3 x 2 x a x b ( because multiplication is commutative, which basically means you can move the numbers and variables anywhere in the expression).
= 6ab ( we leave out the multiplication signs. They are understood.)
The price will be the same after 6 months and the total price will be $145.
Answer:
The number is 48
Step-by-step explanation:
First, let's call the number we are looking for n.
We can then write "two-thirds of the number" as 2/3n
We can also write "one-half of a number" as 1/2n
Finally, we are told 1/2n is the same as 2/3n −8 or: 1/2n = 23n −8
We can now solve for n: 1/2n − 2/3n = 2/3n −8 − 2/3n 1/2n − 2/3n = −8We next need to get the fractions over common denominators, in this case, 6 by multiplying each fraction by the necessary for of 1: (3/3) 1/2n − (2/2) 2/3n = −8 3/6n − 4/6n = −8 − 1/6n = −8.
We can finally solve for n by multiplying by -6 to isolate n −6 ⋅(−1/6)n = −8⋅ − 6
1n = 48
n =48
You answer is going to be: 540
