Micheal solved this inequality as shown. Step 1: -6x (x + 3) + 10 < -2. step 2 : -6× - 18 + 10 < -2. step 3: -6x - 8 < -2 step 4: -6x < 6 step 5: x > -1 what property justifies the work shown between step 3 and step 4
a
step-by-step explanation:
fabric (square meters) cloaks
7 21
4/3 4
step-by-step explanation:
we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.
1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.
we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.
therefore, harry will make 21 cloaks from 7 square meters of fabric.
2. let us find how many square meters of fabric will be needed to make 4 cloaks.
first of all we will find fabric needed for 1 cloak by dividing 2 by 6.
we can see that fabric needed for 1 cloak is square meter. now we will multiply by 4 to find fabric needed for 4 cloaks.
85.3-64 = 21.3
so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams
hope i ! have a great day!
