Answer:
t = 1 1/4 hours
Step-by-step explanation:
Lets first make an equation to represent the situation. t + 1/2 = 1 3/4
Because we cant add fractions with different denominators we have to change 1/2 to 2/4.
Next, we need to isolate t. Subtract 2/4 from both sides of the equation to get 1 1/4.
t = 1 1/4.
Answer:
x = π/4.
Step-by-step explanation:
3sin(2x) = 2sin(2x) + 1
3sin(2x) - 2sin(2x) = 1
1sin(2x) = 1
sin(2x) = 1
When a variable n = π/2, sin(π/2) = 1 [refer to the unit circle].
2x = π/2
x = π/4.

Answer:
47
Step-by-step explanation:
2m+-m=7
3m-8=7
Then add 8 to both sides of the equation.
simplify.
Divide both sides of the equation with the same term.
simplify.
m=5
