Answer:
Danalya napped 1 7/20 hours.
Step-by-step explanation:
Rewriting our equation with parts separated
=3+3/4−2−2/5
Solving the whole number parts
3−2=1
Solving the fraction parts
3/4−2/5=?
Find the LCD of 3/4 and 2/5 and rewrite to solve with the equivalent fractions.
LCD = 20
15/20−8/20= 7/20
Combining the whole and fraction parts
1+7/20= 1 7/20
Answer:
75
Step-by-step explanation:
Number of necklace= k × amount of time spent
6= k × 2/5
K = 6÷2/5
K= 6×5/2
K= 15
Therefore the number of necklace made in 5 hours can be calculated as follows
15 = number of necklace ÷ 5
Number of necklace = 15 ×5
Number of necklace = 75
X=-1.8
To solve first use the distributive property to change the equation to -2x+1 1/3+1=5
Then you subtract 1 from 5 so then the equation looks like this: -2x+1 1/3=4
Next subtract 1 1/3 from 4 to get 3.6
then divide it by -2 and you get -1.8
