Answer:
x = -6
x = 2
Step-by-step explanation:
x² + 4 - 12 = 0
= (x + 6)(x - 2)
x + 6 = 0
x = -6
x - 2 = 0
x = 2
It should be 8/5 cause 4/5 times 24/12= 4/5 times 2/1. then u multiply.
Answer:
Mean = 7
Median = 8
Mode = 3
Range = 9
Step-by-step explanation:
Answer:
y=0.25x
We can think of k as an unknown number.
8×_=2.00
12×_=3.00
20×_=5.00
If we divide 2 with 8 we are left with 0.25.
It's the same for the other numbers so we know the constant is 0.25.
When we use the formula y=0.25x with the numbers above, it is correct.
8×0.25=2.00
12×0.25=3.00
20×0.25=5.00
480 + 192 = 672 students total
16 + 12 = 28 classrooms total
672/28 = 24 students per room
24 * 12 = 288 students that need to be in school B
288 - 192 = 96 students who have to transfer
