Answer:
A - 2x + 4 + 50 = 10x - 2
Step-by-step explanation:
1.) It is the only equation that makes mathematical sense
2.) The sum of angles ABD and DBC equal angle ABC, and ABC = 10x -2
Note:
x=7 if it is important later on
Step-by-step explanation:
do 51,416×4
ans is 245,664
Answer:
Step-by-step explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
12+ 8 7/8+6+s=29 1/4
Convert 1/4= 2/8.
12+ 8 7/8+6+s= 29 2/8
Combine like terms.
26 7/8+s= 29 2/8
Subtract 26 7/8 on both sides.
s= 2.375 or 2 3/8
The unknown side is equal to 2 3/8.
I hope this helps!

Yes, 1 & 2 are correct. 3 would be explaining how you got your answers. For example, you could use number 1 and say you thought about 10 x 3 equals 30 so 3 groups with 8 left over and so on or however your thought process went.
