Answer:
Step-by-step explanation:
4d-4=5d-8
add 4 to both sides
4d=5d-4
subtract 5d from both sides
-d=-4
switch so d is positive
d=4
Answer:
I think its A........ I don't really know.
Step-by-step explanation:
5 x 2 = 10
3.14 x 10 = 31.4
Answer: 150
We know that cos Ф = sin (90 - Ф)
If Ф = 150, then:
cos 150 = sin (150 - 90)
cos 150 = sin 60
Using the equation they gave us:
cos 150 = sin (
- 10)
cos 150 = sin 60
134.4 miles, because 5/7 in decimal form is 1.4, divide 188.3/1.4 = 134.4 miles
