Answer:

Option (d) is correct.

Step-by-step explanation:

The equations are :

-x-2y=-4  .....(1)

3x+y=12 ....(2)

Equation (1) can be rewritten as follow :

-x = -4+2y

x = 4-2y .....(3)

So, to solve the above systems of equations, we must substitute the value of x from equation (3) in equation (2). Hence, the correct option is (D).

What is the ratio of hot chips to total chips?
leva [86]

Answer:

189 chips

Step-by-step explanation:

Most sources I found online say there is about 9 servings in one bag of hot chips. The back of your bag says that 1 serving is 21 chips. So if we do some basic math, 21 x 9, that means the total amount of the chips inside the bag are around 189 chips!

The measure of an interior angle of a regular octagon is how many degrees greater than the measure of an interior angle of a reg
harina [27]

Answer:

Step-by-step explanation:

Sum of interior angle of any polygon = 180* (n- 2 )

Here, n= number of sides

Sum of interior angles of regular octagon = 180 * ( 8-2) = 180 * 6 = 1080°

In regular octagon, all the angles are congruent,

So, measure of an interior angle of regular octagon = 1080/8 =  135°

Sum of interior angles of regular hexagon = 180 * ( 6-2) = 180*4 = 720°

In regular hexagon, all the angles are congruent,

So, measure of an interior angle of regular hexagon = 720/6 =  120°

The measure of an interior angle of a regular octagon is  greater than the measure of an interior angle of a regular hexagon by 15°
