You have to use the distributive property for the numerator on both equations.
X=3.5y
look at it like this, you need 14 tarts so you need 3.5 teaspoons times 4. 14tarts=3.5(4)
x = 3 ; y = 1
Given:
y = -2x + 7
y = 1/3x
Substitute y by its value to find x.
y = y
1/3 x = -2x + 7
x = (-2x + 7) ÷ 1/3
x = (-2x + 7) * 3/1
x = -6x + 21
x + 6x = 21
7x = 21
7x/7 = 21/7
x = 3
Substitute x by its value to solve for y.
y = -2x + 7
y = -2(3) + 7
y = -6 + 7
y = 1
y = 1/3 x
y = 1/3 * 3
y = (1*3)/3
y = 3/3
y = 1
Hello!
The median is the number in the middle when the data is ordered from least to greatest
Order the numbers first
1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11
From here when find the medians which are two 6's which means the median is 6
Hope this helps!
52.8 because 5,280/100=52.8
So the knot is 52.8
