Answer:
Step-by-step explanation:
Given:
Number of eclairs = 3
Number of humbugs = 
Number of mints = 
Therefore, total number of sweets in the jar is,
Now, probability of selecting a sweet to be humbug is given as:
Therefore, the probability that it is a humbug is .
Answer:
C
Step-by-step explanation:
To find x take 180 and subtract 63 and 77
Try breaking these into sections.
Twice: 2 times
The sum of: add
A number: choose a variable, like x
---Thus "the sum of a number and 4" becomes "add x and 4" which, mathematically, is "x+4"
-----Continuing to put it all together, "Twice the sum of a number and four" becomes "2 times (x+4)" which, mathematically, is "2(x+4)"
Is: equals
-------"Twice the sum of a number and four is" becomes "2(x+4)="
23 less than: subtract 23. This one tends to trick people; "23 less than" will become "__ - 23", NOT "23 - __"
three times the number: 3 times x
---"23 less than three times the number" becomes "subtract 23 from 3 times x" which, mathematically, is "3x-23"
-------So the final phrase: 2(x+4)=3x-23"
Answer:
Step-by-step explanation:
This question is attached to:
(4,-1) turns into (1,4) because the equation for that is (x,y)->(y•-1,x)
