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! :)

The straight angle ;
60 + x = 180
So x = 120

A
Step-by-step explanation:
3x9+ 27 + 8= 35
Answer:
96 squared units
Step-by-step explanation:
Please find attached the diagram used in answering this question
The surface area is equal to the area of each shape
Area of a triangle = Area of a triangle = 1/2 x ( base x height)
1/2 x 2 x 3= 3
there are 4 triangles, area of both triangles = 3x4 = 12
Area of rectangle = length x width
Area of middle rectangle = 6 x 7 = 42
Area of two side rectangles = (3 +3) x 7 = 42
surface area = 42 + 42 + 12 = 96
1) in order for two lines to be perpendicular, their gradients must multiply together to get -1
-1/3*b=-1
b=3
5=3(3)+b
5=9+b
b=-4
equation of the line is y=3x-4
2) parallel lines have the same gradient
4=2(-3)+b
4=-6+b
b=10
equation of the line is y=2x-10
