The answer is 5
explanation:
Let's call our number
a
. The statement written as a formula is
a
12
a
9
=
125
We can simplify the fraction, and we have
a
3
=
125
To solve for
a
, take the third root of both sides:
a
=
(
125
)
1
3
=
5
1 meter = about 39 inches.
So you would need to do 3.5 * 39 = 136.5 is your answer
Given:
Charle order 6 sandwiches and $2 kids meals.
Total amount he has = $32
Price of each sandwich is same.
To find:
The amount spend on each sandwich.
Solution:
Let x be the price of each sandwich.
Price of 6 sandwiches = 6x
Price of Kid meals = $2
Total price = 
Total amount he has = $32
Now,



Divide both sides by 6.

Therefore, the amount spend on each sandwich is $5.
The right answer is B
because 1/2=0.5
A. 1/5=0.2
2/9=0.222
4/8=0.5
B. 3/5=0.6
2/4=0.5
4/6=0.6667
-45=-6(-4+3f)
-45=24+18f
-69=18f
f= -23/6 or -3.83
