Mathematics
1 answer:
Free_Kalibri [48]3 years ago

Answer:

x=13

Step-by-step explanation:

since they are vertical angles, they equal each other so set both angles to have them equal each other to find x

8x - 12 = 6x + 14

Add 12 on both sides

8x = 6x  + 26

Subtract tax from both sides

2x = 26

Divide by 2 for both sides

x = 13

-2x+15y=-24<br> 2x+9y=24 <br> solve the system of equation
zhuklara [117]

Answer:

x = 12, y = 0

Step-by-step explanation:

Use elimination.

24y = 0

y = 0

Then plug back into the second equation.

2x + 9(0) = 24

2x = 24

x = 12

Plug back into the first equation to check.

There are 8 rows and 8 columns, or 64 squares
lawyer [7]

Complete Question:

There are 8 rows and 8 columns, or 64 squares on a chessboard.

Suppose you place 1 penny on Row 1 Column A,

2 pennies on Row 1 Column B,

4 pennies on Row 1 Column C, and so on …

Determine the number of pennies in Row 1

Determine the number of pennies on the entire chessboard?

Answer:

255 in the first row

18,446,744,073,709,551,615 in the entire board

Step-by-step explanation:

Given

Rows = 8

Columns = 8

Solving (a): Number of pennies in first row

The question is an illustration of geometric sequence which follows

1,2,4....

Where

a =1 --- The first term

Calculate the common ratio, r

r = \frac{T_2}{T_1} = \frac{4}{2} = 2

The number of pennies in the first row will be calculated using sum of n terms of a GP.

S_n = \frac{a(r^n - 1)}{n - 1}

Since, the first row has 8 columns, then

n = 8

Substitute 8 for n, 2 for r and 1 for a in S_n = \frac{a(r^n - 1)}{r - 1}

S_8 = \frac{1 * (2^8 - 1)}{2 - 1}

S_8 = \frac{1 * (256 - 1)}{1}

S_8 = \frac{1 * 255}{1}

S_8 = 255

Solving (b): The entire board has 64 cells.

So:

n = 64

Substitute 64 for n, 2 for r and 1 for a in S_n = \frac{a(r^n - 1)}{r - 1}

S_{64} = \frac{1 * (2^{64} - 1)}{2 -1}

S_{64} = \frac{(2^{64} - 1)}{1}

S_{64} = \frac{(18,446,744,073,709,551,616 - 1)}{1}

S_{64} = \frac{18,446,744,073,709,551,615}{1}

S_{64} = 18,446,744,073,709,551,615
