P minus p over 6 = p over three plus 2

1 answer:

8 0

The sum of opposites equals zero, which makes the equation zero over 6 equals p over 3 + 2 then you simplify the equation, multiply both sides by 3 which you will get 0=p+6 now we move variables to the left side and change its sign which is -p=6 so your answer will be p=-6 hope that helps you understand

A heptagon has unequal sides that are in a pattern. Each side is 2 more than twice the side of the smaller one before it. Write

bixtya [17]

Heptagon has unequal sides and each side is 2 more than twice the side of the smaller one before it.

Heptagon is a 2 dimensional geometric shape that has got 7 sides.

Lets say the length of smallest side is 'x' units.

Length of the second side will be 2 more than twice the smaller side so the side length will be:

$2\times x+2=2x+2$

Now the length of the third side will be 2 more than twice the second side that is:

$2(2 \times x+2)+2=2(2x+2)+2=4x+4+2=4x+6$

Similarly, length of the fourth side will be:

$2(4x+6)+2=8x+12+2=8x+14$

Similarly, length of the fifth side will be:

$2(8x+14)+2=16x+28+2=16x+30$

Again, length of the sixth side will be

$2(16x+30)+2=32x+60+2=32x+62$

And the length of the seventh side will be

$2(32x+62)+2=64x+124+2=64x+126$

Now, perimeter of any geometric shape is the sum of the lengths of the sides:

Adding all the sides we get:

$x+(2x+2)+(4x+6)+(8x+14)+(16x+30)+(32x+62)+(64x+126)$

$=x+2x+2+4x+6+8x+14+16x+30+32x+62+64x+126$

$=127x+240$

Therefore, the expression for the perimeter of the required heptagon is $127x+240$ .

kyle works at a donut factory where a 10-oz cup of coffee costs 95 cents, a 14-oz cup costs $1.15, and a 20-oz cup costs $1.50.

8_murik_8 [283]

Answer:

The number of a 10-oz cup of coffee was 6

The number of a 14-oz cup of coffee was 6

The number of a 20-oz cup of coffee was 5

Step-by-step explanation:

Let

x ----> the number of a 10-oz cup of coffee

y ----> the number of a 14-oz cup of coffee

z ----> the number of a 20-oz cup of coffee

we know that

$x+y+z=17$ -----> equation A

$10x+14y+20z=244$ ----> equation B

$0.95x+1.15y+1.50z=20.10$ ----> equation C

Using a equation System Solver (Wolfram Alpha)

The solution is

x=6, y=6, z=5

see the attached figure

therefore

The number of a 10-oz cup of coffee was 6

The number of a 14-oz cup of coffee was 6

The number of a 20-oz cup of coffee was 5

(24-y)/4=4 <br> i need to solve for y but cannot remember how to execute the process

Svet_ta [14]

You need to isolate the variable by itself on one side of the equation. You do so by performing the inverse operations that were done to the variable....

(24-y)/4=4 multiply both sides by 4

24-y=16 subtract 24 from both sides

-y=-8 divide both sides by -1

y=8
