Hello! :)
9 = (3/8)y
Solve for y.
Isolate y by dividing both sides by 3/8, or multiplying by its reciprocal (8/3)
9 · (8/3) = (3/8)y · (8/3)
72 / 3 = y
y = 24
Answer:
B
Step-by-step explanation:
57 over three means
It is the same as asking how many times does 3 go into 57, or how many miles is their per one gallon.
57 divided by 3 equals 19, so B would be the correct answer.
Answer:
10√2 inches (second option)
Explanation:
visualise a square in your head. then, imagine a diagonal running through it. that diagonal would separate the square into two triangles. so to find the diagonal, we first need to find the length of the square (which would serve as the base and height of the triangle).
we can simply divide the perimeter by 4 to get the length of each side, which would then be 40 ÷ 4 = 10.
next, we can use the formula of the pythagorus theorum! it states that a² + b² = c², where a, b and c are represented by the following image:
for our equation, this would translate to 10² + 10² = c², and c would be the length of the diagonal.
100 + 100 = c²
200 = c²
in radical form, the square root of 200 would be 10√2. therefore, the length of the diagonal is 10√2 inches, which is the second option.
i hope this helps! :D
