1. Let
Shortest piece = x
Longest piece = y
Third piece = z
2.
Shortest piece = x
Longest piece = 40 + x
Third piece = (40 + x)/2 OR 20 + 0.5x
3. Add all the expressions since you know that the total of all the pieces is 120 inches
40 + x + 20 + 0.5x + x = 120.
4. Add the whole numbers first, then add the variables.
40+20=60
x+0.5=2.5x
60+2.5x=120
5. To get rid of the 60, do the opposite of addition which is subtraction and subtract 60 from both sides.
2.5x=120-60
2.5x=60
6. Do the same but rather than addition, do the opposite of multiplying which is dividing, on both sides.
x=60/2.5
x=24
7.
Shortest piece = 64-40=24 inches
Longest piece = 24+40=64
Third piece = 64/2=32
Answer:
no it is not
Step-by-step explanation:
it would be 54
Answer:
A
Step-by-step explanation:
The answers are slope intercept which is the easiest form. y=mx+b (m=slope and b is intercept[where crosses y axis]) the slope of this graph is 2 and the intercept is -3 so the Slope-Intercept form is y=2x-3
decimal expansion of 1/7 is 0.14285714285
Notice the 6th digit is 7, the 7th digit is 1, the 8th digit is 4, etc…
Therefore, you just divide which digit you want to know by 6, then look at the digit of the remainder. If the remainder is 0, then you are looking at the 6th digit.
For example if you want to know the 13th digit, 13/6 = 2 remainder 1. Therefore, you look at the first digit.
so for 2007 th digit we have,
Answer: 2007/6= 334 , remainder 3, so we look at third digit , which is 2
