Answer:
Cost of One Journal = $3.99
Cost of One pen = $0.59
Step-by-step explanation:
Let
Cost of One Journal = x
Cost of One pen = y
We can make equation from given statements.
Mr. Bowden purchases 18 journals and 40 pencils for $95.42.
Ms. Jacinto purchases 11 journals and 16 pencils for $53.33.
Now solving these equations to find the value of x
Multiply eq(1) with 2 and eq(2) with 5
We get the value of x is: x=3.99
Now, putting value of x in equation 1 to find value of y.
So, we get the value of y: y = 0.59
Now, finding the costs:
Cost of One Journal = x = $3.99
Cost of One pen = y = $0.59
Answer:y=16.8
Step-by-step explanation:
proportional means that x/y= constant
so there the constant is 1.75
if x=29.4 then 29.4/y =1.75
y = 29.4/1.75
Answer:
C. Determine the principal square root of both sides of the equation.

Answer:
1.15
Step-by-step explanation:
Multiply each shot by its point value. Then add. Divide this sum by the total number of shots taken.
288*2 + 79*3 + 340*0 = 813
----------------------------------------
288 + 79 + 340 = 707
813 / 707 = 14.992
The weighted average is approximately 1.15 points per shot.
