Which expression has the same value as 15 + 9 ÷ 3 − 2
a. 15 + (9 ÷ 3) − 2
b. (15 + 9) ÷ (3 − 2)
c. 15 + 9 ÷ (3 − 2)
d. (15 + 9) ÷ 3 − 2

Answers

Answer 1

Answer:

The answer is A. 15+(9÷3)-2

Step-by-step explanation:

Well first we need to solve the current equation

15+9÷3-2

We should use PEMDAS. Since we do not need to do any parentheses, exponents, or multiplying. So we need to move onto division. 9÷3 would equal 3 so not the original equation looks like...

15+3-2

Now we will move on to adding and add 15 and 3 which equals 18. This leaves us with our last step....

18-2

We need to subtract 2 from 18 which will leave us at 16. Now that we have solved the original equation we can solve the others to find the answer using PEMDAS

A. 15+(9÷3)-2

15+3-2

18-2

16

B. (15+9) ÷(3-2)

24÷1

24

C. 15+9 ÷ (3-2)

15+9÷1

15+9

24

D. (15+9) ÷ 3-2

24÷3-2

8-2

We have all the answers now and only one has the same value which is...

A. 15+(9÷3)-2

This equals 16 as does our original answer

hector's bag contains three kinds of marbles. he is 2 times more likely to randomly select a white marble than a striped marble. he is equally likely to select a white marble as a dotted marble. of the original bag of 10 marbles is tripled, keeping the ratios of striped, dotted, and white marbles the same, how many of each type of marble are in the bag?

Answers

Answer: 12 white, 12 dotted and 6 striped

Step-by-step explanation:

There are 10 marbles. There are twice as many white marbles than striped marbles, and there are the same amount of white marbles and dotted marbles.

Trial and error concludes that there are 4 white marbles, 4 dotted marbles and 2 striped. Then, you have to triple them (multiply by 3)

4x3=12

4x3=12

2x3=6

12 white, 12 dotted and 6 striped

Select all that apply. Which of the following shows that 5/6 = 15/18 is a proportion?
5 • 15 = 6 • 18
5 • 18 = 6 • 15
5.6/6.3 = 5/18
5+10/6+12 = 15/18

Answers

Answer:

5 · 18 = 6 · 15

Step-by-step explanation:

5/6 = 15/18

If this is proportional, then if we flip it, it should work,

To do this, we'll need to do the opposite to both sides

Which we'll multiply 15 by that 6 under the 5, and the 5 by the 18 which was under the 15

So;

5 · 18 = 15 · 6

Which can be rewritten as

5 · 18 = 6 · 15
