Answer: One approach is to express

8x

2y

so that the numerator and denominator are expressed with the same base. Since 2 and 8 are both powers of 2, substituting 23 for 8 in the numerator of  

8x

2y

gives

(23)x

2y

which can be rewritten

23x

2y

Since the numerator and denominator of have a common base, this expression can be rewritten as 2(3x−y). In the question, it states that 3x−y=12, so one can substitute 12 for the exponent, 3x−y, which means that

8x

2y

=212

The final answer is A.

Dataset: 147; 159; 164; 182; 172; 171; 162; 163; 157; 145; 164; 188; 172; 163; 162; 164 and 166. a) Arrange the data into a stem
Molodets [167]

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 =\frac{total sum}{numberof terms}

Mean=\frac{2800}{17}

Mean= 164.70

Median⇒since there are 17 terms

Median= \frac{N+1}{2}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

Mario eats twice as many as Yolanda. If Yolanda eats 6 walnuts every day, how many walnuts does Mario eat in a week?
stepladder [879]

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
