The diagram shows that
AB = 5
AC = AB+BC = 5+2 = 7
DE = 7
DF = DE+EF = 7+x
So,
AB/AC = DE/DF
5/7 = 7/(7+x)
5(7+x) = 7*7
5(7+x) = 49
35+5x = 49
5x = 49-35
5x = 14
x = 14/5
So EF = 14/5 in fraction form
In decimal form, EF = 2.8 (since 14/5 = 2.8)
Answer:
True.
Step-by-step explanation:
The left side of a "two column proof" is used for your "work" and the right side justifies your statements and is your "proof."
Distribute
4x+4(less than) -6
Subtract 4 on both side
4x(less than) -10
divide 4 both sides
x(less than)-2.5
(Final answer is bold) Good luck
Answer:
263/10 as a decimal equals 26.3
Step-by-step explanation:
To write 263/10 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 263 by 10 what we write down as 263/10 and we get 26.3
