Answer:
48.983.
Step-by-step explanation:
(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).
Using order of operations (PEMDAS):
20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:
= 20.003 + [35.85 - 6.87] Now the outer parentheses:
= 20.003 + 28.98
= 48.983.
The question is incomplete:
Tavon has a gift card for $115 that loses $2.50 for each 30-day period it is not used. He has another gift card for $95 that loses $2 for each 30-day period it is not used.
Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
Answer:
115-2.5x=95-2x
The value of the gift cards will be equal after 40 30-day periods.
Step-by-step explanation:
From the information given, you can write the following equation:
115-2.5x=95-2x, where x is the number of 30-day periods the gift card is not used.
Now, you can solve for x:
115-95=-2x+2.5x
20=0.5x
x=20/0.5
x=40
According to this, the answer is that the value of the gift cards will be equal after 40 30-day periods.
Step-by-step explanation:
2 x 2 + x - 4 = 0
4 + x - 4 = 0
<u>+</u><u>4</u> <u>+4</u>
8 0
<u>8</u> + x = <u>0</u>
8 8
x = 0
For the - 4 + 4 part, it cancels out because it's 0 and for the 8 divided by 8 part, it cancels out too. x is 0 because 0 divided by 8 is 0.
Hope this helped!
