X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
Answer:
26.4 m
Step-by-step explanation:
The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse. Hence,
sin 40° = 
= 
c = 
<u> c = 26.4 m (3 sf)</u>
Here is the solution for the given problem above:
Given: 5/8 yard of ribbon = total length of the ribbon
1/12 yard = length of the ribbon after Tom cut it equally
? = number of pieces of 1/12 yard from 5/8 yard
So to divide fractions, here is the solution
5/8 divided by 1/12
5/8 multiplied by 12/1
5x12 is 60
8x1 is 8.
So 60/8 would be 7.5. Therefore, the number of pieces that was cut from the 5/8 ribbon is 7.5. Hope this answer helps.
