Answer:
2j-42
Explanation:
The phrase is “42 less than twice Janelle’s age”. Basically, this can be separated into “42 less than” and “twice Janelle’s age”. “Twice Janelle’s age” infers that Janelle’s age is doubled; This can be achieved by 2j because it multiplies Janelle’s age by 2(Times 2 is doubling, times 3 is tripling, and times 4 is quadrupling). The second part is “42 less than” meaning something, in this case Janelle’s age, is subtracted by 42 because less than means negative/minus; This is written as “-42”. So, when we put “42 less than Janelle’s age” together, it becomes -42+2j, which ordered correctly becomes as 2j-42.
Answer:
No its not a proportion, the numerators can't be divided evenly
Step-by-step explanation:
T=b+2c+3j, if b,c,j are 8,3,4 respectively
t=8+2(3)+3(4)
t=8+6+12
t=26
So they chop down 26 trees.
Answer:
d = 102 m
Step-by-step explanation:
A cross-country skier moves 36 meters eastward, then 44 meters westward, and finally 22 meters eastward. We need to find the distance covered by the skier. We know that, the distance covered by an object is equal to the sum of its journey. So,
distance = 36 m + 44 m + 22 m
Distance = 102 m
So, the skier's distance covered is 102 m.
