The chessboard is about 26.4 centimeters long. to find the answer you need to know the length of one side of a square, which is about 3.3 centimeters, because the area is 11, so the square root of 11 is about 3.3 centimeters. there are 8 squares, so you have to multiply 8 times 3.3 which equals 26.4.
y= 1/10x - 6
Which if you plug in 70 for x, y equals 1.
Rebecca has $1 and Tim has $70, together they have $71.
Answer:
The other person is correct, my bad I got mixed up with the numbers
The answer is A. Slope is rise/run. According to the graph, you can trace out and see that it rises 1 and goes to the right 4 times. This means that it has a positive slope of 1/4. And the line crosses the y intercept at y = 3
So answer choice A is correct.
Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions
