Answer: First solve the parentheses using order of operations. Then add and subtract from left to right.
Demo:
(3 * 11) = 33
Equation now looks like:
63 - 21 + 33
63 - 21 = 42
Equation now looks like:
42 + 33
42 + 33 = 75
The value of this expression is 75.
Answer:
Yes the stand would make a profit, a $25 profit to be exact.
Step-by-step explanation:
the equation is 3n>100+0.50n
if the stand sells 50 then n=50 making it 3(50)>100+0.50(50).
by doing the multiplication then adding you'll get 150>125 since 3×50 is 150 ans 0.50×50 is 25 and you add the 25 to 100.
which means it'll gain $150 and spend $125 on maintaining the stand and for supplies with a $25 left over. It would make a profit

Answer:
2y = x, which is a proportional relationship.
Step-by-step explanation:
See the table attached.
The table gives the ordered pair represents a proportional relationship.
Take at least two pairs of the value of x and y.
Let they are (6,3) and (10,5).
Now, the equation for the straight line passing through the two points is given by
⇒ 2(y - 5) = x - 10
⇒ 2y - 10 = x - 10
⇒ 2y = x
Hence, we can write x ∝ y and the constant of proportionality is 2. (Answer)
