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
</span>
The answer would be $42.4. $50 minus $10 is $40. Multiply that by 106% because of tax, and you get $42.4.
Hope this helped! :)
Answer:
17 in
Step-by-step explanation:
Rectangle:
(4*2)+(5*2)
8+10 =18
Triangle:
5+4+3 =12
Both:
12+18 = 30
minus where the rectangle and triangle are together
30-3 = 17
2 1/4 = 2 times 4 + 1 = 9/4 times by 1/3 = 4/12 simplest form is 3/4 inches
