The perimeter of the triangle is 56 cm, and the same values for x and y are used to construct the rectangle shown, where the length is 8 cm longer than the width. Find the values of x and
y.
ty
I
x+3
2x
6
2y - 4
First, use the rectangle to find x in terms of y.
Using two equations relating x and y, solve for the value of y.
c. Finally, use the above value for y to find x.
(1) 2x+4y+6=56
(2) L=W+8
(3) 2y-4=(x+3)+8
2y-4=x+11

Phyllis and chen are saving money to go to a football game. each friend starts with some money and saves a specific amount each week. phyllis made a graph to show the total she has saved at the end of each week. chen wrote an equation to show the total, y, he has saved at the end of each week, x. y = 15x + 15 compare the amount that each friend has when both friends start saving. select the correct answer from the drop-down menu to complete the statement. phyllis starts with $ and chen starts with $

The weight of full–grown tomatoes at a farm is modeled by a normal distribution with a standard deviation of 18.4 grams. the 95 percent confidence interval for the mean weight of the tomatoes is calculated using a sample of 100 tomatoes. what is the margin of error (half the width of the confidence interval)?
