Answer:
The value of expression 4 square root 81³ is 2916 .
Step-by-step explanation:
Given expression as :
4 square root 81³
Let the expression written as x =4 
or, x = 4 × 
Or, x = 4 × 729
I.e the square root of = 729
∴ x = 2916
so, the value of expression is x = 2916
Hence The value of expression 4 square root 81³ is 2916 . Answer
Answer:
Martina is 53 inches tall.
Step-by-step explanation:
In order to write an expression that relates the siblings heights we need to attribute variables to each brother. First we will call Martina's height as "m", then we can call her little brother's height as "b". The problem states that Martina's height is 3 inches less than twice the height of her brother so we have:
m = 2*b - 3
Then the problem gives us the height of her brother that is 28 inches tall, so b = 28. We can now compute Martina's height:
m = 2*28 - 3 = 56 - 3 = 53 inches.

Step-by-step explanation:
You multipy 7/8 and 6 and then simplify if needed to get how long it will take
So to solve this question the first step should be to make 7 equal to 42. To do this multiply 7 by 6, likewise with x-4.
The new equation should be 42/6x-24 = 42/12.
We now can just get rid of the numerators (top number) to get 6x-24=12.
The next step is to add 24 to both sides which would leave you with 6x=36.
Divide by 6 and the answer should be x=6
