Answer:
The length of DF is 15
Step-by-step explanation:
Since the two lines are equal, which is given by the markings on the triangle, then you can set the two lengths equal and find x.
7x - 13 = 3x + 3
4x - 13 = 3
4x = 16
x = 4
Now that we know x = 4, we can plug into the DF length to find its amount.
DF = 7x - 13
DF = 7(4) - 13
DF = 28 - 13
DF = 15
Step-by-step explanation:
You have 5 digits.Youdonot say if duplication is allowed. I will assume not
For the first digit you have 5 choices. One of the 5 digits is gone.
You now have 4 digits to choose from. You pick one. Now you have but 3 left.
The total answer if 5*4*3*2*1 = 120
Answer:
5x-y +5 =0
Step-by-step explanation:
y – 5x = 5
5x-y +5 =0
Answer:
90 miles
Step-by-step explanation:
60 miles per hour + 30 = 90
1/2 of 60 = 30
The uncertainty in x is the horizontal width of the rectangular marker, which is 0.05 mm.
The uncertainty in y is the height of the rectangular marker, which is 0.1 g.
