Answer: 6 to 1, 6: 1 or 
Explanation:
In mathematics, the purpose of a ratio is to compare the quantity or values of two different items. For example, if in a recipe 1 spoon of sugar needs to be added for every 3 spoons of water the ratio of spoons of sugar to water is 1 to 3.
In this context, the first step is to find the values of the two items compared. In the case presented these items are the eyes in a spider vs the number of spiders. Also, it is known each spider has 6 eyes. This means the ratio of eyes to spides is 6 to 1, which means for each 6 eyes there is 1 spider. Moreover, this ratio can be written as 6 to 1, using a colon as 6: 1, or as a fraction .
Answer:
A The sum of the first 11 terms is 88
Step-by-step explanation:
Since -4 - (-7) = -1 - (-4) = 2 - (-1) = 3
Your sequence is an arithmetic sequence with a common difference of 3.
The formula for the sum of an arithmetic sequence is
where 
In your case 
, n = 11 and 
We know everything except the eleventh term.
So, we need to find the eleventh term or 
= 
+ (n - 1)d
= -7 + (11 - 1)3
= -7 + 30 = 23
Now, S = 
The sum of the first 11 terms is 88
The answer to your question above would be: 7z-2/z-7
74 + 5x + (3x + 2) = 180 ** The sum of the 3 angles in a triangle is 180**
74 +5x + 3x + 2 = 180
76 + 8x = 180
8x = 180 - 76
8x = 104
X = 13
