Hi!
So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599.
Take the parts I put in bold, and write the equation.
$230 + x = $599
Now we need to find x.
Whatever we do to the equation, we do it to both sides.
Our goal is to isolate x on one side.
Subtract 230 from both sides.
$230 - $230 + x = $599 - $230
x = $369
The answer is A. $230 + x = $599 x = $369
Hope this helps! :)

Step-by-step explanation:
you did not even try a calculator to find the result ?
64 is 8×8 or 8².
so, sqrt(64) = 8.
similarly for 4 :
4 is 2×2 or 2².
so, sqrt(4) = 2
so,
sqrt(64)/ sqrt(4) = 8 / 2 = 4
so, d. is the right answer.
((n-2)×180)/n = 156
(n-2)×180=156n
24n =360
n =15
360/n =36
n = 10
a)15 b)10
Answer:
72
Step-by-step explanation:
1 out of 10 do not recommend naps, so 9 times as many do recommend naps.
9 × (8 doctors) = 72 doctors . . . . . recommend naps
Answer:
f(1) = 2
Step-by-step explanation:
Since y is a function of x, that is;
y = f(x)
f(1) implies the value of y when x = 1.
To obtain this value we draw the vertical line x = 1 and check where the line intersects the graph of f(x).
In this case, the line x = 1 will intersect with the graph of f(x) on the line y = 2. The function f(x) assumes the value 2 between x = 0 and x = 4. Therefore,
f(1) = 2
