6x +30 -3x +6 =12x +18
3x +36 =12x +18
3x-12x = 18 -36
-9x = -18 | -1
9x =18
x= 18/9
x=2
Answer:
numero tres es correcto
Step-by-step explanation:
Answer:
The first four terms in the sequence 57, 50, 43, and 36
Step-by-step explanation:
Put the numbers in place of x (or n in this case).
You subtract that number you put in place of n by 1.
You then distribute the difference of n and 1.
You then subtract the distributed number by 57
The mean of data is 164.70, median and mode of data are 164
Given that Dataset: 147; 159; 164; 182; 172; 171; 162; 163; 157; 145; 164; 188; 172; 163; 162; 164 and 166. and asked to arrange data in stem and leaf diagram and asked to determine mean, mode and median form the stem and leaf diagram
STEM LEAF
14 5 7
15 7 9
16 2 2 3 3 4 4 4 6
17 1 2 2
18 2 8


Mean= 164.70
Median⇒since there are 17 terms
Median=
the term
Median=9th term=164
Mode⇒ most frequent number
Mode⇒164
Therefore, 164 is mode and median ,164.70 is mean
Hence,The mean of data is 164.70, median and mode of data are 164

let
x-------> walnuts that Mario eats in a week
y-------> walnuts that Yolanda eats in a week
we know that
x=2y-------> equation 1
y=6*7-------> y=42 walnuts
substitute the value of y in equation 1
so
x=2*42-----> x=84 walnuts
therefore
the answer is
Mario eat in a week 84 walnuts
