The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3

Set this up as a proportion with the model stuff on top and actual building stuff on bottom.
. Cross multiply to get x = 780. The actual building is 780 inches. In feet that is 65.
Answer:
1
Step-by-step explanation:
you move the decimal to the right twice, so it goes from .01 to 1.00 if that makes sense :)
Answer:
3(3a+15b)
Step-by-step explanation:
GCF: 3
Find all the prime factors between 3 and 15
3: 1,3 1*3
15: 1,3,5,15 (1*15 3*5)
3 is the GCF between the 2 numbers.
$52.50 / 42 = 1.25
$1.25 per each slice
