46 follows 45 and 46 is preceded with 47
Numbers are 4 and 8
<u>Step-by-step explanation:</u>
Step 1:
Let the numbers be x and y. Given that their sum is 12 and difference is 4. Form equations for this data.
⇒ x + y = 12 ------ (1)
⇒ x - y = 4 -------- (2)
Subtract eq (2) from (1)
⇒ 2x = 8
⇒ x = 4
Step 2:
Find y.
⇒ y = 12 - x = 12 - 4 = 8
12 hours u half to divide it equally
Answer:
x = 9
Step-by-step explanation:
5x+4 = 49
subtract 4 from both sides
5x = 45
divide both sides by 5
x = 9
Answer:
The common ratio is -3
Step-by-step explanation:
we know that
In a<u> Geometric Sequence</u> each term is found by multiplying the previous term by a constant called the common ratio
In this problem we have
-2,6,-18,54...
Let
a1=-2, a2=6,a3=-18,a4=54
a2/a1=6/-2=-3
a3/a2=-18/6=-3
a4/a3=54/-18=-3
Each term (except the first term) is found by multiplying the previous term by -3
therefore
we have a geometric sequence and the common ratio is -3
