Answer with Step-by-step explanation:
a. The difference between 8 forty-sevens and 7 forty-sevens
Let ⊕ repesents forty- sevens.
So, Model can be represented by
8⊕ - 7⊕
=⊕⊕⊕⊕⊕⊕⊕⊕-⊕⊕⊕⊕⊕⊕⊕
=⊕
Mathematically,
let x represents forty-sevens.
So, it becomes
b. 6 times the sum of 12 and 8.
Mathematically, it is expressed as
Let 12 be written as 4×3
and 8 be written as 4×2
Let ⊕ represents 4 i.e. fours.
so, there are sum of 2 fours and 3 fours.
So, it becomes,
6×(⊕⊕+⊕⊕⊕)
=6×(⊕⊕⊕⊕⊕)
=⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕
=4×30
=120
It should be just 12b, since they all have the same exponent, they can all be combined.
We know that
volume of the box=length*width*height
V=L*W*H----> H=V/[L*W]
V=576 in³
L=12 in
W=8 in
so
H=576/[12*8]----> H=6 in
the answer is
the height of the box is 6 in
Answer:
So you first count how much times the numbers go up,then you add the number you get it is 6+ you add them with 13 and you get 19.
Step-by-step explanation:
So you first count how much times the numbers go up,then you add the numbers so 1 is not enough 2 is not enough 3 is not enough 4 is not enough 5 is not enough 6 is enough, so we add the six with the number that we are adding which is 13,then you get 19
