Answer:
Equation : 15x = 270
Where, x = number of days,
Their food will last in 18 days.
Step-by-step explanation:
Given,
Total food = 270 pounds,
Consumption of food per day = 15 pounds
Let x be the number of days,
Then, consumption of food in x days = 15x
∵ Total food will last,
If total consumption = total food
⇒ 15x = 270
Which is the required equation,
Divide both sides of the equation by 15,
We get,
x = = 18
Hence, their food will last in 18 days.

Answer:
Step-by-step explanation:
You need 2 things in order to solve this equation: a trig identity sheet and a unit circle.
You will find when you look on your trig identity sheet that
so we will make that replacement, getting everything in terms of sin:
Now we will get everything on one side of the equals sign, set it equal to 0, and solve it:
We can factor out the sin(theta), since it's common in both terms:
Because of the Zero Product Property, either
or
Look at the unit circle and find which values of theta have a sin ratio of 0 in the interval from 0 to 2pi. They are:
The next equation needs to first be solved for sin(theta):
so
and
Go back to your unit circle and find the values of theta where the sin is -1/2 in the interval. They are:
