Explanation:
A)
Let t and f represent the numbers of two-point and four-point questions, respectively.
__
B) The number of points for each type of question is the product of the point-value per question and the number of questions of that type.
2t + 4f = 100 . . . . . the test is worth 100 points
t + f = 40 . . . . . . . . there are 40 questions on the test
_____
<em>Additional comment</em>
The test will have 30 two-point questions and 10 four-point questions.
25+1=26 25x4=100 this is the answer
Step-by-step explanation:
Rearrange this algebraically to solve for
Price per pound
. To do this, divide both sides of the equation by
Number of pounds
to get
Price per pound
by itself.
Total cost = number of pound
=Total of cost /Number of pounds
=33/5
=$6.6
8^2 + b^2 = 24^2
64 + b^2 = 576
-64 -64
b^2 = 512
Take the square root from b^2 and 512 =
b = 22.627
Answer 22.63 (rounded up)
It is 8 ft long on the unmeasured side length
