Answer:

The answer is C.

Step-by-step explanation:

There is an explanation in my assignments that say a good and easy way of grouping is to find a way to make 100, then add or subtract whatever is next. In this case (70+30) makes 100, then you must add 72, and because its a double diget (i cant spell, sorry!) and and so are the two zeros in the triple diget, so it should not be hard to put the two numbers together if there are zeros, (plural). I hope you understand this!

Answer:

D. 95 + 47 + 5.12 12 ÷ 4 ≠ 4 ÷ 12.

Step-by-step explanation:

(70 +30) + 72 B. 21 + (-14) + (-53) O C. 67 +1 - 18. So 12÷4≠4÷1/4 + 3/4 + 2. C. 20 + 80 + (-11)

Jessica is a custodian at Oracle Arena. She waxes 20 m2 of the floor in 3/5 of an hour. Jessica waxes the floor at a constant ra

Ghella [55]

to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

$\frac{20}{3/5} = \frac{x }{1 }$

you can use cross multiplication to solve for x:

$\frac{3}{5} x = 20$

$3x = 100\\x = 100/3$

so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.

Least to greatest √5,-2.1,0.5,-0.5,5/100

Sladkaya [172]

Answer: -2.1, -0.5, 5/100, 0.5, √5

Step-by-step explanation:

Start with the negative numbers. Take the absolute value - the ones with the largest absolute value are the farthest from 0, so they are the smallest numbers.

-2.1, -0.5

Then, convert the numbers not in decimals to decimals.

5/100 = 0.05

√5 is about 2.3.

5/100, 0.5, √5
