Answer:
20 questions
Step-by-step explanation:
12/15 can be reduced to 4/5
you can create a ratio like the following:
4/5 = x/25
cross-multiply to get:
5x = 100
x = 20
If the question is 3*2/3=2+N/3
N=0
If the question is 2/3=2+N/3
N=-4
Answer:
{−1008,−504,−252,−126,…}
Step-by-step explanation:
-504÷(-1 008)=0.5
(-252)÷(-504)=0.5
(-126)÷(-252)=0.5
In this sequence ,we multiply by 0.5 each time to get the next term
then it’s a geometric sequence.
Answer:
2y-4x
Step-by-step explanation:
<span>xy-5
x=5 and y=2
We basically plug in the number values they gave for x and y
(5)(2)=10-5=5
Final answer: 5
Note: I assume y=2 because you already have the x value stated, the only other vairble there is y
