1 is D, because if you wrote out all the choices as equations, you would get that A is 1/2 n - 3, B is also 1/2 n - 3, C is 1/2 - 3, and D is 1/2(n - 3)
2 is A, because 3 times her age minus 4 is 3x-4, with x as Marcys age
3 is C, because although 11 x 5 is 55, it says that 5 times a number is LESS than 55, so the answer is 10, or C
4 is B because the mode is 92, the mean is 122, and the median is 88, which would mean that mean>mode>median
Answer:
She made 7 field goals
Step-by-step explanation:
With the data we can make 2 equations
1 x + 2 y= 26
x+y=19 and y=19-x
Where,
x= free throws
y=field goals
Replacing y in the first equation
1 x + 2 (19-x)= 26
1 x + 38-2x= 26
1 x - 2x= 26 - 38
- 1x= -12
x=12
y=19-12
y=7

Round and then see what the number you have too add, subtract , multiply, and divide and then you would find the answer
Answer: $3.25
Step-by-step explanation:
First you need to calculate the cost of the 8 pounds of nuts.
Cashews = 4 x $4 = $16
Peanuts = 4 x $2.50 = $10
The total cost of 8 pounds of nuts equals $16 + $10 = $26
In order to calculate the cost of 1 pound of the mixture you need to divide the total cost by the total weight.
$26 / 8 lbs = $3.25 / lb
The cost of one pound of the mixture is $3.25.
