3a plus 7. you group the whole numbers together and than the a's. so 3+4 is 7. 2a + a is 3a.
Answer:
$2327.5
Step-by-step explanation:
The stock of company A lost 2% today .
Let the price of the stock at the beginning of the day be A.
Therefore, a 2% loss of A = $46.55
That’s
2% /100% x A = $46.55
0.02 x A = $46.55
Divide both sides by 0.02
0.02/0.02 x A = $46.55/0.02
A = $2327.5
The price of stock at the beginning of the opening day was $2327.5
Hey there!
P(y) = 0.46
P(x) = 0.49
P(y') = 0.54
P(x') = 0.51
P(y and x') = 0
x = person that watched the film
y = person that visited the gift shop
P(y and x') / P(x')
0.1 / 0.51 = 0.196
Now convert that into a percentage!
0.196 = 19.6%
Your answer is 19.6%
Hope I helped!

Answer: The length and width are 50 and 30 meters (or 30 and 50 meters).
Step-by-step explanation:
To solve this question, we can represent variables for the length and width in two equations.

To solve for one of the variables, you'll have to substitute one of the variables, so solve for one of them:


Now, we have a standard quadratic equation that we can factor. When factoring, you'll get this:

This tells us that the width could be either 50 or 30.
Substitute 50 into one of the equations to find the length:
2 (l) + 100 = 160
l = 30.
The length and width are 50 and 30 meters (or 30 and 50 meters).
