Answer:
9x - 2x + 62 = 9x + 24
Number of correct answer each obtained = 19
Step-by-step explanation:
Given that:
Number of correct answers = x
POINTS for correct answers = 9
POINTS for incorrect answers = - 2
SCHOOL A:
Number of correct answers = x
Number of incorrect answers = x
Initial point = 62
Initial point + 9(number of correct answers) + - 2(number of incorrect answers)
62 + 9x - 2x
SCHOOL B :
Number of correct answers = x
Number of incorrect answers = 0
Initial point = 24
Initial point + 9(number of correct answers) + - 2(number of incorrect answers
24 + 9x
Since they end up tied :
School A = School B
62 + 9x - 2x = 24 + 9x
9x - 2x + 62 = 9x + 24
Number of correct answers gotten :
9x - 2x + 62 = 9x + 24
7x + 62 = 9x + 24
7x - 9x = 24 - 62
-2x = - 38
x = 19
Hence, Number of correct answers each obtained = 19
Area of a circle=pi x r^2= 3.14 x 8^2(half of the radius)=3.14 x 64=200.96
area of triangle= 1/2 bh=1/2(16)(8)=1/2(128)=64
200.96-64=136.96 sq.ft
If you multiply out the answers, which is easier, then you can find the correct answer.
The factors need to multiply together to create the original problem, so it's just a matter of plug and chug.
The answer is B.
Answer:
The equations which describe this situation are:
C. f + (2f) + (2f + 2.50) = 11.25
E. 5 f = 8.75
Step-by-step explanation:
Here, the number of loaves of bread purchased = 3
The price of a loaf of French bread = f
The price of whole grain bread = 2 x ( Price of the french bread)
= 2 x (f) = 2 f
The price of cinnamon raisin bread
= ( Price of the whole grain bread) + $2.50
= 2 f + $2.50
Also, the total price paid for the 3 loaves of bread = $11.25
⇒ The cost of ( French + whole grain + Cinnamon raisin) bread = $11.25
or, f + (2f) + (2f + 2.50) = 11.25
or, 5 f = 11. 25 - 2.50 = 8.75
or, 5 f = 8 . 75
Hence the equations which describe this situation are:
C. f + (2f) + (2f + 2.50) = 11.25
E. 5 f = 8.75
