Answer:

x=11∘

Step-by-step explanation:

So to do this, you need to understand that the sum of angles in a triangle is 180∘. If we understand this, we can add up all of the angles in ΔGHI and make the sum 180∘ to get an algebraic equation:

10x+9+3x+13+x+4=180 - Combine like terms

14x+26=180 - subtract 26 on both sides

14x = 154 - divide by 14 on both sides

x=11∘

Answer:

(10x + 9) \degree + (3x + 13) \degree + (x + 4) \degree = 180 \degree \\ 10x + 3x + x  +  9 + 13 + 4 = 180 \degree \\ 14x + 26 = 180 \\ 14x = 180 -26 \\ 14x = 154  \\ x =  \frac{154}{14}  \\  \boxed{x = 11}

To test subtitle 11 in x, your angles should add up to 180 degrees

What is the slope of the lines that are parallel to the line defined by the equation y = -x – 4?
Svet_ta [14]

Answer:

slope = -1

Step-by-step explanation:

parallel lines have the same slope,

y = -x – 4

=> y = -1(x) -4

          ↑ slope

y = mx + b

     ↑ slope

a store received 500 containers of milk to be sold by Febuary 1. Each container the store sold $0.83 and sold for $1.67. The sto
FrozenT [24]
$409.80.

The amount of net profit the store makes on each container is given by 1.67-0.83 (the amount it is sold for subtracted by the amount it costs the store), which is $0.84 per container.  They sell 470 containers, so the net profit at this point is 470(0.84) = $394.80.

However, since the distributor is giving the store a $0.50 refund on all every container under 500 that the store sells, the store gets additional money back:

500-470 = 30 containers not sold
30(0.50) = 15

So the total profit is $394.80 + 15 = $409.80.
