Answer:
y = - 3
Step-by-step explanation:
Given the 2 equations
6x + 11y = - 3 → (1)
4x + y = = 17 → (2)
Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x
24x + 44y = - 12 → (3)
- 24x - 6y = - 102 → (4)
add (3) and (4) term by term to eliminate x
0 + 38y = - 114
38y = - 114 ( divide both sides by 38 )
y = - 3
Divide 128 by 4. Then multiply that by 3 to get the answer for the weight of box A.
Hey there! Here's your answer:
f (n + 1) = f(n) - 5
Here's why:
<u>6, 1, –4, –9, –14, ...</u>
We need to analyze our current sequence to know what pattern will follow.
6 - 5 = 1
1 - 5 = -4
-4 - 5 = -9
-9 - 5 = -14
(And So On)
We can see successive terms are found by subtracting 5 from previous terms.
I hope this helps! Have a good day :).
With "infinite" numbers of successive random samples, the mean of the sampling distribution is equal to the population mean .As the sample sizes increase, the variability of each sampling distribution decreases so that they become increasingly more leptokurtic.
We have to see how many times 55 pence fits into 3 Pounds:
3/0.55=?
if we multiply both numbers by 100, so that there are no fractions, we have:
300/55=5 and 25 cents left
(check: 5*55=275)
so the correct answer is 5 yoghurts.
