-4x + y = 6
-5x - y = 21
add both of them
-9x = 27
x = -3
(-4*-3) + y = 6
-12 + y = 6
y = 18
Answer:
(c) 22
Step-by-step explanation:
The range of a set of data is found from a box and whisker plot by subtracting the lower whisker value from the upper whisker value:
range = 66 -44 = 22
The range in the number of pretzels is 22.
Answer:
5
Step-by-step explanation:
20%=0.2
25 x 0.2 = 5
You can build as many numbers as you like: just pick three primes and repeat them as required.
The only caution is that you have to pick large enough primes to make sure that the result is larger than 1000.
Since
, it is enough that the prime repeating three times is larger than 10.
So, for example, we can pick
- 2, not repeating
- 3, repeating twice
- 11, repeating 3 times
The result is
