Answer:
FALSE
Step-by-step explanation:
Add 8 to both sides
-4a /5= 10
Multiply both sides by 5
-4a= 50
A= - 12.5
Answer:
x = -5/3
-1.667
Step-by-step explanation:
Answer:
tan ∅ = 24 / 7
Step-by-step explanation:
cos ∅ = 7 / 25
sin^2 ∅ + cos^2 ∅ = 1
sin^2 ∅ + (7 / 25)^2 = 1
sin^2 ∅ = 1 - 49 / 625
sin^2 ∅ = 625 - 49 / 625
sin^2 ∅ = 576 / 625
sin ∅ = root 576 / 625
sin ∅ = 24 / 25
tan ∅ = sin ∅ / cos ∅
tan ∅ = 24/25 / 7/25
Therefore, tan ∅ = 24 / 7
OPTION 4. 24 / 7
66 - 18 = 48
Nonfiction : Fiction
48 : 18
Divide both by 6
