points and every shot he made behind the three-point line he earned 3 points. Mr. Sarpy shot a total of 50 shots and earned a total of 115 points. Write a system of equations that best models x, the number of 2 point shots, and y, the number of 3 point shots.

Answer:

x + y = 50 (1) and 2x + 3y = 115 (2); x = 35, y = 15

Step-by-step explanation:

Since x represents the number of 2 point shots and y represents the number of 3 point shots. If the total number of shots is 50, then x + y = 50 (1)

Also, the total 2 point shots is number of 2 point shots × points per shot = 2x and the total 3 point shots is number of 3 point shots × points per shot =  3y. Since the total number of points is 115, then

2x + 3y = 115 (2)

So, the system of equations are

x + y = 50 (1) and 2x + 3y = 115 (2)

We can solve for x and y by substituting x = 50 - y into (2)

So, 2(50 - y) + 3y = 115

100 - 2y + 3y = 115

100 + y = 115

y = 115 - 100

y = 15

So, x = 50 - y

= 50 - 15

= 35

Semmy [17]

Answer:

Hi there!

Your answer is:

Smallest number: 24

Median number: 25

Largest number: 26

Step-by-step explanation:

three consecutive numbers:

n, n+1, n+2

5(n+2)= (n+1+n)3 -17

5n+10= (2n+1)3-17

5n+10= 6n+3 -17

5n+10= 6n-14

-6n

-n+10= -14

-10

-n= -24

/-1

n= 24

ΔABC ~ ΔDEF. What is the length DF?
lana [24]

ΔABC ~ ΔDEF

that means the ratio of DF to AC = the ratio of DE to AB

x:3.5 \\6:4

cross multiply

4x=6(3.5)\\4x=21\\x=\frac{21}{4}\\ x= 5.25

so DF = 5.25 cm
