Answer:

36x - 80

Step-by-step explanation:

Combine like terms by adding/subtracting coefficients

3x -7x = -4x

40x -4x = 36x

There are no constants to combine so simply keep it as is

Answer:

Quadratic function

Explanation:

It is not linear because the difference between y values is not constant.

( $10-5\neq 5-2$ for example) In a linear function, the difference between y values would be constant.

What is the area of the hexagon? 60 m 2 80 m 2 100 m 2 120 m 2

larisa86 [58]

We can think of this hexagon as two trapezoids with the same area. Each has height 5 and bases 6 and 10.

$A = 2 \left(\frac 1 2 (b_1 + b_2) h \right) = h(b_1 + b_2)$

$A = 5(6 + 10) = 80$

Answer: 80 square meters, second choice

Stephen and Laura want to split a bag of fun-sized candy, and decide to use the divider-chooser method. The bag contains 100 Sni

Lubov Fominskaja [6]

Answer:

a) $4.14

b) No

c) 28 Snickers, 40 Milky Ways, 63 Reese's

72 Snickers, 60 Milky Ways, 37 Reese's

Step-by-step explanation:

Since 1 Snickers is $0.01, 1 Milky Ways is $0.03, and 1 Reese's is $0.04:

30 Snickers: 30(0.01) = 0.3

40 Milky Ways: 40(0.03) = 1.2

66 Reese's: 66(0.04) = 2.64

The value is: 0.3 + 1.2 + 2.64 = 4.14

The total value is: 1 + 3 + 4 = 8

A fair share must have the same value, 8/2 = 4. Since one half is 4.14 which is more than 4, it is not a fair share.

First half:

28 Snickers: 28(0.01) = 0.28

40 Milky Ways: 40(0.03) = 1.2

63 Reese's: 63(0.04) = 2.52

Second half:

72 Snickers: 72(0.01) = 0.72

60 Milky Ways: 60(0.03) = 1.8

37 Reese's: 37(0.04) = 1.48
