Answer:
x =2
Step-by-step explanation:
The x- intercept is when y = 0
Hence, 5x - 2y = 10
5x - 2(0) = 10
5x = 10
Therefore, x = 2
The Associative property of addition is where you group the numbers differently with parenthesis. That equation could be written as (8+6) + 7 = 21 or (7+8) + 6 = 21
All you have to do is regroup the numbers
Answer:
I think it's 0.04
Step-by-step explanation:
Each 10 years the pupil gets smaller by 0.4 millimeters

again dont take my word for it im not a goddess lol
Answer:
4600
Step-by-step explanation:
This is an arithmetic sequence with common difference d between consecutive terms.
d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4
The sum to n terms of an arithmetic sequence is
= 
[ 2a + (n - 1)d ]
where a is the first term
here a = - 6, d= 4 and n = 50, hence
= 
[ (2 × - 6) + (49 × 4) ]
= 25 ( - 12 + 196 )
= 25 × 184
= 4600
54.5981500331 is the answer
