Step-by-step explanation:
a)
8÷2=4
12÷3=4
27÷9=3
•it does'nt always take the same amount of time to serve each customer .
•10×3=30
b)
according to the question
2=18 point
4=36 point
8=72 point
18=9×2
36=9×4
72=9×8
so 1dollar =9point
•each dollar spent appears to earn the same number of point
•because 81=9×9, it costs 9 dollar
Answer:
x ≥ −4
The line is shaded to the right of −4 where the values are greater. The closed circle indicates that −4 is include
If 3/5 of all the brownies is 21, then 5/3 of 21 is the number of the brownies that Lauren brought in.
That probably sounded super confusing. When multiplying a number by a reciprocal of a fraction (a fraction where the numerator and denominator is reversed), the previous fraction multiplication is reversed.
Multiplying 21 with 5/3 will give us the original number of brownies.
Lauren originally brought 35 brownies.
Answer:
Hollow-circle rightward-facing arrow with start point number 1.
Step-by-step explanation:
x/8 > 2/(3 + 2^2 + 1) * 2
Multiply both sides by 2:
x/4 > 2/(3 + 2^2 + 1)
Resolve bracket:
x/4 > 2/(3 + 4 + 1)
x/4 > 2/8
x/4 > 1/4
Multiply both sides by 4:
x > 1
To graph this on the number line, you must draw an arrow facing to the right starting from the number 1. It is important that the circle with the arrow is hollow - this is because a hollow circles means more/less than, whereas a filled circled means more/less than or equal to, and this inequality is only more than, not more than or equal to.
46+19+54= 119, so the answer is 119
