Answer:
does the x means multiply or its a variable.. and is it really written that way?
the complete question in the attached figure
16.017 in. ÷ 0.370 in=43.289189 in--------- > <span>the correct level of precision is with three decimals
therefore
the answer is 43.289 in</span>
Answer:
The answer to this question is B
Answer:
40
Step-by-step explanation:
given the fact that mary made 85% of her free throws attempts,
thus she missed the rest 100 minus 85= 15% of the attempts. let the total number of attempts be x. thus:
15% of x=6
15/100 x=6
solve by cross multiplying
x=6 100/15
x=40
hope this helps
Step-by-step explanation:
x = number of true/false questions
y = number of multiple choice questions
x + y = 40
2x + 3y = 144
from the first equation we get
x = -y + 40
this identity we can then use in the second equation
2(-y + 40) + 3y = 144
-2y + 80 + 3y = 144
y + 80 = 144
y = 64
and
x + 64 = 40
x = -24
that does not make any sense.
something is wrong with the problem description.
just think about it :
40 questions - if all of them would be multiple choice tests (creating the max. possible points for 40 questions), we could have only 40×3 = 120 points.
but the description says 144 points.
for 144 points we need at least 48 (144/3) questions.
that does not fit.
the described system does not have any natural number solution. therefore we are getting such crazy numbers as result, when we try.
