Cherie measures and records the lengths and sizes of the same style of a sandal found at a shoe store.
Butoxors [25]
I found the missing data: 
table:
foot length (in)    Shoe size(S)
8                                   6
8.5                                7
9                                   8
9.5                               9 
10                               10

Choices:
<span>S = x – 2
S = 2x – 10
S = x + 6
S = 2x + 4
</span>
Among the choices, the correct equation is S = 2x - 10

S = 2(8) - 10 = 16 - 10 = 6
S = 2(8.5) - 10 = 17 - 10 = 7
S = 2(9) - 10 = 18 - 10 = 8
S = 2(9.5) - 10 = 19 - 10 = 9
S = 2(10) - 10 = 20 - 10 = 10

Y=3x+2 and x+2y=11 how do you solve these linear equations by using substitution
Pani-rosa [81]
Plug in y=3x+2 into the y in the second equation.

x + 2(3x+2) = 11
x + 6x + 4 = 11
7x + 4 = 11
7x = 7
x = 1

then, plug the x value into x in the first equation.

y = 3(1) + 2
y = 3 +2
y = 5

At the ice cream parlor,sundaes cost $4.25 and waffle cones cost $3.75.You and your friends have $50 to spend.Your group buys 5
stich3 [128]

Answer:

You can buy 7 waffle cones.

Step-by-step explanation:

Let sundae = x

Let waffle cones = y

4.25x + 3.75y ≤ 50

4.25 (5) + 3.75y ≤ 50

21.25 + 3.75y ≤ 50

3.75y ≤ 28.75

y ≤ 7.666666666

* round to the nearest whole to get 7
