Ayumi, a chef, wants to determine how many meals she cooked in
one evening. The table shows the four meals
she made and the number of people that
were served each meal. (Lesson 1-3)
Meal Number of People
Lasagna
27
Spaghetti & Meatballs 21
Steak & Potatoes
19
Shrimp Scampi
13
She uses the following steps to determine
how many total meals she cooked.
Step 1: 27 + 21 + 19 + 13
Step 2:27 +13 + 21 + 19
Step 3: (27 +13) + (21 +19)
Step 4: 40 + 40
Step 5: 80
Which property did Ayumi use in Step 3?

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
