753,249 - 575,388 = 159,861
i hope it's right :)
Let the 1st number be x; 2nd number be y; 3rd number be z.
x + y + z = 79
x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first
Therefor,
x + (x * 5) + (x+16) = 79
1st step, multiply the 2nd number: x * 5 = 5x
x + 5x + x + 16 = 79
Add all like numbers:
7x + 16 = 79
To get x, transfer 16 to the other side and change its sign from positive to negative.
7x = 79 - 16
7x = 63
To get x, divide both sides by 7
7x/7 = 63/7
x = 9
To check. Substitute x by 9.
x + (x * 5) + (x+16) = 79
9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.
*see attachment for the diagram of the two box plots referred to here.
Answer:
2 inches
Step-by-step explanation:
The median of a box plot is the data value that lies exactly where the vertical line divides the box into two.
Therefore:
Median for Class 1 = 17 inches
Median for class 2 = 15 inches
The difference in the medians of both box plots = 17 - 15 = 2 inches
Step-by-step explanation:
parallelogram area is:h×base
10×14=140
we have two so
140×2=280
traingle is:h×base/2
18-10=8=h
8×14/2=56
56×3=168
168+280=448
Answer:
A) FGE~HGE
Step-by-step explanation:
Because all of the points match up with the points on the other side.
It would be similar to closing a sand-witch and lining up all the edges with each other.
