Rearrange x/4-(-5)=0
Simplify x/4
-5 = -5/1 = -5*4/4
x- (-5*4)/4 = x+20/4
x+ 20/4 = 0
x+20/4 * 4 = 0*4
The equation now takes the shape: x+20=0
subtract 20 from both sides of the equation: x=-20
Answer: x=-20
Answer:
(D)How many hours during the week do you eat in the cafeteria?
Step-by-step explanation:
This question directly gives her the information she needs. She wants to find out how much time students spend eating in the cafeteria and that is exactly what this question is asking.
Answer:
104
Step-by-step explanation:
This is not a distributive property question though.
A distributive property has a number (a) outside the parenthesis
a(b+c)
so in this case a(40+64)
then you would multiply a by both numbers
40a+64a
then add them together
104a
However if it is a number outside the parenthesis and not a variable, it will come out different
For example
5(40+64)
(5*40)+(5*64)
200+320
520
Hope this helps!
