-2(3x - 9) + 5x = -10
-6x + 18 + 5x = -10
-6x + 5x = -10 - 18
-x = -28
x = 28 <===
Answer:
185
Step-by-step explanation:
It seems like you're using the Pythagorean theorem, which would mean that b is equal to
, which is equal to
. The number beneath the radical symbol is <u><em>185</em></u>.
Ok, the expression represents the total amount paid because the 4 is the total tax being ADDED to the rest of the expression is 3(26-7). We need to distribute the parentheses by doing: 3*26-3*7. The 3*26 is the three soccer balls multiplied the cost of each ball without the balls being on sale, which is the $26. This brings you to $78. However we then need to do the 3*7, which is the three soccer balls being multiplied by the amount of money you save on each ball being purchased since they're on sale. So that would be $21. Then, $78-$21=$57. $57 is the cost of the three soccer balls without the tax, so we then plug 57 back into the original equation and add 4 to it, since the $4 is the tax. And finally, $57+$4=$61, which is the total amount of money the coach spent on the 3 soccer balls.
For the second part of the equation: Since parentheses comes first in PEMDAS, we need to solve the parentheses first by solving 3(26-7). I've explained how to distribute that in the first explanation above. But basically you just distribute the parentheses using the three, which is 3*26-3*21. You then add four when you finish distributing the equation, since addition comes after parentheses in PEMDAS
Answer:
It will be $506.876 more.
Step-by-step explanation:
The equation for continuously compounded interest is given by
.......... (1)
where, A is the final amount, P is the principal amount, r is the annual interest rate and t is the number of years.
Now, in our case, P = $500, r = 7% i.e 0.07 and t = 10 years.
Then, from equation (1),
dollars
Therefore, the interest will be (A - P) = $(1006.876 - 500) = $506.876. (Answer)
