What is<br> −5.4−(−3.2)−5.4−(−3.2) ?

Mrs. Austin teaches forty-eight students. One-third of her students are out sick with the flu. How many students are sick?

Aneli [31]

16 of the students are sick. How I got this was, divide 48 by 3 and you get 16 therefore 1/3 of 48 is 16.

Can someone answer this truthfully

juin [17]

Answer:

1- 4x -7 =29, x= 9

2-x/3 - 8 = 12, x=60

Step-by-step explanation:

4x-7 =29

4x= 29 +7

4x= 36

x= 9

x/3 -8 =12

x/3 = 12+ 8

x/3 = 20

x= 20(3)

x= 60

The distributive works for multiplication and addition. You switch the order of the problem but it doesn't change the final prod

Alja [10]

Answer:

Is there a question?

Step-by-step explanation:

If it is, by the way I look at it, To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

In ABC, what is the measure of angle B?

NeX [460]

Answer:

D

Step-by-step explanation:

The sum of two remote interior angles (a remote interior angle is the interior angle that is not supplementary to the exterior angle given -- in this case A and B are remote angles) equals the exterior angle.

In This case A + B = 140

A = x + 2

B = 2x

x +2 + 2x = 140

3x + 2 = 140 Subtract 2 from both sides

3x = 138 Divide by 3

x = 138/3

x = 46

<B = 2x

<B = 2*46

<B = 92

Evaluate the expression

larisa86 [58]

Answer:

$12-[20-2(6^2\div3\times2^2)]=88$

Step-by-step explanation:

So we have the expression:

$12-[20-2(6^2\div3\times2^2)]$

Recall the order of operations or PEMDAS:

P: Operations within parentheses must be done first. On a side note, do parentheses before brackets.

E: Within the parentheses, if exponents are present, do them before all other operations.

M/D: Multiplication and division next, whichever comes first.

A/S: Addition and subtraction next, whichever comes first.

(Note: This is how the order of operations is traditionally taught and how it was to me. If this is different for you, I do apologize. However, the answer should be the same.)

Thus, we should do the operations inside the parentheses first. Therefore:

$12-[20-2(6^2\div3\times2^2)]$

The parentheses is:

$(6^2\div3\times2^2)$
