Answer: x=5
Explanation:
sin=opposite side/hypotenuse
The opposite side is x and the hypotenuse is 10.
So your equation is: sin(30)=x/10
In order to get x by it self times ten to each side of the equation.
10 x sin(30)= x
Put 10 x sin(30) into graphing calculator and make sure your calculator is set to degrees.
Your answer:
5= x
Work on paper:
K so you have to set 2 equations like this
x meaning the amount of adults
and y meaning the amount of kids
x+y=11
13.5x+8.25y=111.75
Then use substitution method and you get
x=11-y from the first equation
plug that in to the second and you get
13.5(11-y)+8.25y=111.75
Solve for y in that equation by distributing and then combining like terms
148.5 - 13.5y + 8.25y = 111.75
148.5 - 5.25y = 111.75
Then, you need to subtract 148.5 from each side and cancel the negatives
5.25y=36.75
solve for y and you get
36.75/5.25 = 7
y=7

Answer:
5.907 kilometers.
Step-by-step explanation:
Please consider the complete question.
According to Jax's pedometer, he walked 2.783 km while taking care of the livestock in the morning and 3.124 km taking care of the livestock in the evening. How far did Jax walk while taking care of the livestock today?
To find the total distance covered by Jax, while taking care of the livestock, we will add distances covered by Jax in the morning and evening.
Therefore, Jax walked for 5.907 kilometers, while taking care of the livestock.
