Final answer:
The phrase '10 times as many as 1 ten' simply means making 10 groups that are exactly the size of 1 ten (which is your original amount). Hence, '10 times as many as 1 ten' is equal to ten tens.
Explanation:
In a mathematical perspective, when you have 1 ten and you want to find out what 10 times as many is, you simply multiply your original amount by 10. In this case, if you multiply 1 ten by 10, the product is 100. However, when you look at it in terms of tens, your original amount is simply 1 group of ten, and if you create 10 groups exactly that size, you end up with 10 tens. So 10 times as many as 1 ten is 10 tens.

a1 = -2(1) + 4
a1 = -2 + 4
a1 = 2
a2 = -2(2) + 4
a2 = -4 + 4
a2 = 0
a3 = -2(3) + 4
a3 = -6 + 4
a3 = -2
a4 = -2(4) + 4
a4 = -8 + 4
a4 = -4
So the first four terms of the sequence are: 2, 0, -2, -4
The answer is:
2, 0, -2, -4

50 rabbits
12% increase per month.
Solve for the increase per month. (multiply 50 by 12%)
50 x 12%= n
50 X .12= 6
6 rabbits per month is increased.
We will solve for the total number of months it will be when the number of rabbits reached up to 1000.
1000-50 +6=n
n=1000-50
6
n = 950 ÷ 6
n= 158.33.... months or 158 months and 10 days.
Since there are 50 rabbits already in the farm, we will subtract 50 from 1000. Every month the rabbits increased 12 % which is 6 (12% of 50) so, we will divide 950 (1000-50=950) by 6. The result is 158.33... months or 158 months and 10 days or .33 month.
158 months x 6= 948 rabbits (950-948=2)
Since 6 rabbits are increased per month, we need to calculate the two rabbits to make up 950.
2 rabbits ÷ 6 rabbits per month =.33 or 33% of the total increased.
33% of 30 days (1 month) =9.9 days or 10 days when rounded off.
