Answer:
5
Step-by-step explanation:
Let x be the number of cell phones with keyboards needed.
40% = 
=
x+45 = 40 -----1
x+120 = 100 -----2
You would want to make the total of 1 the same as 2.
1×
: 2.5+112.5 = 100 -----3
Now 2 and 3 are equal.
x+120 = 2.5x+112.5
Isolate the x and numbers.
120-112.5 = 2.5x-x
Simplify.
1.5x = 7.5
x = 
× 7.5
x = 5
The manager of the store needs to add 5 more cell phones with keyboards.
I only know 23
6x-4 x=4-6=-10
4x+24 x=24-4=20
So! 20-(-10)=10 or 30 because you change the sign with this rule
if the sign are the same you keep change, change. which means keep 20 change - to + and change - to +, so then it becomes 20+(+10)
Answer:
f=4
Step-by-step explanation:
1) first we have to get the "f" by itself. to do this we subtract the 1 from the right side of the equation.
2) and what you do to one side you ALWAYS do to the other side!!! so subtract 1 from the 5 also
3) this leaves you with 4=f
hope this helps!
