PLEASE HELP ME!! This assignment is already late!If d + 5 >= (greater than or equal to) 17, complete each inequality.

d >= ?

d + ? >= 20

d - 5 >= ?

Answers

d + 5 >= 17
We can subtract 5 from each side:
d >= 12
To get 20 on the right, we have to add 8 to each side (20-12=8).

d + 8 >= 20

To get d - 5 from the first expression (d + 5 >= 17) we have to subtract ten from each side (5-10=-5) and we get:

d - 5 >= 7

26 and 1/6

Answer: 26 and 1/6

72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6

What is the total cost of 1.9 cubic meters of soil if it sells for $40

Answers

Answer:

Step-by-step explanation:

Total cost = 1.9* 40 = 76.0 = $76

When unit rate is given,multiply.

Final answer:

The total cost of 1.9 cubic meters of soil is $76. This is calculated by multiplying the amount of soil bought (1.9 cubic meters) by the cost of one cubic meter of soil ($40).

Explanation:

To calculate the total cost, we have to multiply the amount of soil bought (in cubic meter) by the cost of one cubic meter of soil. Here, the student is buying 1.9 cubic meters of soil and the cost of one cubic meter of soil is $40.

So, Total cost = amount of soil * cost of one cubic meter of soil
= 1.9 * 40
= $76

Therefore, the total cost of 1.9 cubic meter of soil is "$76."
