x ≈ 38.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = 
= 
, then
x = 
( ) ≈ 38.7° ( to 1 dec. place )
Answer:
y = 5
x = 10
Step-by-step explanation:
-4(2y) + 11y
-8y + 11y = 15
3y = 15
/ 3 /3
y = 5
x = 10
The answer for the equation is 21
X = how much Tim has
y = how much Tom has
x + y = 2.40
x = 3y
Substitute 3y for x
3y + y = 2.40
4y = 2.40
y = 0.60
Plug in y value into previous equation
x = 3(0.60)
x = 1.80
ANSWERS: Tim has $1.80 and Tom has $0.60
