To solve for this, we need to use the Distributive Property, which allows us to multiply the number/variable outside of the parenthesis by all numbers/variables inside of the parenthesis. Once we've done that, we can attempt to simplify the equation.
Our current equation is:
7a + 3(9+5a) = 0
Let's use the Distributive Property.
3(9 + 5a)
3(9) + 3(5a)
27 + 15a
Our current equation now is:
7a + 27 + 15a = 0
Combine like-terms.
15a + 7a = 22a
22a + 27 (If this is not being solved, THIS is your answer as an expression)
Subtract 27 from both sides
22a = -27
Divide both sides by 22 to get a.
a = -27/22.
If we are not solving for a, but getting an expression, your answer is:
22a + 27.
If we are solving for a, our answer is:
a = -27/22.
I hope this helps!
Answer:
900 calories
Step-by-step explanation:
First you have to find the unit rate, how many calories are there in ONE cracker? To find that you have to divide 60 ÷ 12 = 5 and to check with the other one, 75 ÷ 15 = 5
So, one cracker is 5 calories. Now, how many calories are in 180 crackers? You multiply, 180 x 5 = 900
That means there are 900 calories in 180 crackers.
Hope that helps and have a great day!
The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
Step-by-step explanation:
the longest spin of a basketball on one finger is 255 minutes.
We need to find how many hours is that.
So, we need to convert 255 minutes into hours.
We know that,
60 minutes = 1 hour
Using Unitary method:
60 minutes = 1 hour
1 minute = 1/60 hour
255 minutes = 1/60 * 255 hour
255 minutes = 255/60 hour = 4.25 hour
255 minutes is 4.25 hour.
So, The longest spin of a basketball on one finger is 255 minutes or 4.25 hours.
