Answer:
one number is 10 and the other is 2
Step-by-step explanation:
10 is 5 times 2 and 10+2=12.
20 books per box and x number of boxes.
To write an equation you have to figure out what variable you are solving for, which is x. Then you see what x is, which is the number of boxes. Finally you figure out what it takes from the given no. to get to the answer, x.
y = no. of books
x = y/20
Answer:
Rearrange the numbers to their like terms.
which is 2x-x=56-20.
x=36.
Answer:
B
Step-by-step explanation:
(Sorry about the crude drawing)
The drawing shows what the triangle with a terminal side in Quadrant IV looks like.
Secant is the ratio of the hypotenuse to the adjacent side of the angle. In the given ratio, we can set 5 as the hypotenuse and 2 as the adjacent side (you can see them labeled in the picture).
Now, we want to find sin, which is (opposite)/(hypotenuse). However, we don't know the opposite. We can find it by using the Pythagorean Theorem:
So, the opposite side is . But, we see that since it's in the fourth quadrant, it must be negative, so we have opposite = . Now, we can find the ratio because hypotenuse = 5:
sin(θ) = .
Thus, the answer is B.
Hope this helps!
