Answer:
so whats the answer
Step-by-step explanation:
Height: width
4:3 = 24:x
x = 18
The frame will be 18 inches wide.
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>
All you gotta do is subtract both of the numbers to get how much you need.
93 - 75 = 18
We can double check to see if it's right by using addition
18 + 75 = 93
Sonny needs to borrow 18$ to meet his required amount :D
Answer:
10=y/11-13
We move all terms to the left:
-10-(y/11-13)=0
-y/11+13-10=0
We multiply all the terms by the denominator
-y+13*11-10*11=0
We add all the numbers together, and all the variables
-1y+33=0
We move all terms containing y to the left, all other terms to the right
-y=-33
y=-33/-1
y=+33
