Answer:
3 : 1
Step-by-step explanation:
Gold : tetra
21 : 7
3 : 1
Answer: -3 and 12
Step-by-step explanation:
First: your +12 is where you start
Your coordinates for that is (0,12) so, put one point on (0,12)
Second: your slope is -3. So at (0,12) you go down -3 and go to the right 1.

Answer:
w=5
Step-by-step explanation:
Due to the subtraction property of equality, you have to subtract 7 from both sides to isolate the W.
DE is 31 units, EF is 31 units and DF is 62 units
Step-by-step explanation:
A mid-point of a line segment
- Divides it into two congruent parts
- The length of each part is half the length of the line segment
∵ E is the mid-point of segment DF
- That means E divides DF into two parts DE and EF and the
lengths of them are equal
∴ DE ≅ EF
∵ DE = 6x + 1
∵ EF = 7x - 4
- Equate them
∴ 6x + 1 = 7x - 4
- Add 4 to both sides
∴ 6x + 5 = 7x
- Subtract 6x from both sides
∴ 5 = x
Substitute the value of x in DE and EF to find their length
∵ DE = 6(5) + 1
∵ DE = 30 + 1
∴ DE = 31 units
∵ EF = 7(5) - 4
∴ EF = 35 - 4
∴ EF = 31 units
∵ DF = DE + EF
∴ DF = 31 + 31
∴ DF = 62 units
DE is 31 units, EF is 31 units and DF is 62 units
