What is 3 - 1.5? Please also explain!

Answers

Answer 1

Answer: Numbers have decimals in between them. For example, between 1 and 2 are the decimals: 1.1, 1.2, 1.3 through 1.9, then it rounds up to 2.

If we need to move up a decimal, we move that same number of times. To go from .5 to our whole number, we move 5 times. .6, .7, .8, .9, then rounding up to 2.

To go from 1.5 to 2 we have to add .5.

Then we just go from 2 to 3. This is 1 whole number.

So the difference is 1.5

3-1.5=1.5

(Or to see it easier 1.5 + 1.5 = 3)

Answer 2

Answer: 3-1.5=1.5 if you need to show work add 1.5 +1.5 and the 5s will be a 10 0 under 1 over to left then 1+1+1= 3

Answers

For Complete question: refer attached figure

Correct Answer:

The system of inequalities that represents this situation is:

$75x+ 95y \leq 85,000$ , $x \leq y$

Step-by-step explanation:

We have , x be the number of $75 trees and y the number of $95 trees . And it's given that the tree budget must not exceed $85,000 . So,

⇒ $75(x)+ 95(y) \leq 85,000$

⇒ $75x+ 95y \leq 85,000$

⇒ $5(13x+ 19y) \leq 5(17,000)$

⇒ $13x+ 19y \leq 17,000$

Therefore, Inequalities are $75x+ 95y \leq 85,000$ , $x \leq y$ .

Janice needs to purchase a new uniform for a job she just accepted. The store indicates that she may have a 30% discount, but that she will need to pay the 8% sales tax on the uniform. If the uniform lists at retail cost of (c), which of the following choices would Janice use to correctly calculate her total cost (T) of the uniform?A. (T) = (c) – 0.3c + 0.08c
B. (T) = 0.7c + 0.08(0.7c)
C. (T) = 0.7 (0.3c + 0.08c)
D. (T) = 0.7 (c – 0.08c)

Answers

I'm not sure I I think its C let me know if its right

Final answer:

The correct formula to calculate Janice's total cost of the uniform is (T) = 0.7c + 0.08(0.7c), as stated in choice B.

Explanation:

To calculate Janice's total cost of the uniform, we need to take into account the 30% discount and the 8% sales tax. The correct formula to calculate the total cost (T) is (T) = 0.7c + 0.08(0.7c), which corresponds to choice B.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

We have the expression:

72 divide 0.75

To find the value of the expression:

Use division operation,

72 / 0.75

= 72 ÷ 0.75

Simplifying,

= 72 x 100 / 75

= 7200/75

= 96

Therefore, the answer is 96.
