Answer:
$966
Step-by-step explanation:
Sam's investment = 828
Paul's investment will be temporarily marked as x.
We need to divide 828 by 6 = 138 to find the result, x.
We multiply that by 7. 7 x 138 = 966.
We can write in 3 different ways:
828 : 966
828/966
(or in fraction form, I don't have a fraction line.
Answer:
C
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, so n = 6
sum = 180° × (6 - 2) = 180° × 4 = 720° → C
Well you equal out the two angles to each other and solve for x. then you just plug the the number you got for x back into the equations to get your answers

Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8
