Answer 1

Which statement best describes the expression 3 + y ÷ 2?
The quotient of 2 and the sum of 3 and y

The quotient of the sum of 3 and y, and 2

The sum of 3 and the quotient of 2 and y

The sum of 3 and the quotient of y and 2

Answer 2

ok tell this-> what does \(y ÷ 2\) represent? :)

Answer 3

im stuck

Answer 4

for example if you have -> \(6 ÷ 2\)
well this can be simplified like this-> \(6 ÷ 2=3\)

here 3 is nothing but the quotient of 6 and 2
:)
now if you have this-> \(y ÷ 2\)
what does this represent

Answer 5

some number and 2 ?????

Answer 6

here y is being divided by 2
and y÷2 is nothing but the quotient of y and 2
and then you are adding 3 to it
\(\color{red} 3+y÷2\)

how will you write it all in words?

Answer 7

i mean D

Answer 8

\(\Huge \color{green}✓\) yes :) D is correct

Answer 9

thx

Answer 10

np

Answer 11

The work of a student to find the dimensions of a rectangle of area 8 + 12x and width 4 is shown below:

Step 1: 8 + 12x
Step 2: 4(4) + 4(8x)
Step 3: 4(4 + 8x)
Step 4: Dimensions of the rectangle are 4 and 4 + 8x

In which step did the student first make an error and what is the correct step?

Step 2; 4(2) + 4x(2)
Step 2; 4(2) + 4(3x)
Step 3; 4 + (4 + 8x)
Step 3; 4 + (4 ⋅ 8x)

Answer 12

the student factored out \(4\) in the second step

he did this-> step 2: \(4(4)+4(8x)\)

he just factored out 4 from the step 1: \(8+12x\)

did he do this correctly?

Answer 13

hmmmm....

Answer 14

okay lets factor out \(4\) from step 1: \(8+12x\)

we can write \(8\) as \(4(2)\)
and \(12x\) as \(4(3x)\)

now we can write \(8+12x\) like this-> \(4(2)+4(3x)\)

so do you think that what the student did is correct?

Answer 15

yes

Answer 16

he did this -> \(4(4)+4(8x)\)
and we did it correctly and we got this-> \(4(2)+4(3x)\)

Answer 17

ok it makes more sense now

Answer 18

yes so is he correct?

Answer 19

no...
?

Answer 20

yes he isn't correct on the step 2
:)

Answer 21

:P

Answer 22

Which of these is the algebraic expression for "4 times the sum of 2 and y?"

4 ⋅ 2 + y
4(2 + y)
2 + 4 ⋅ y
2(4 + y)

Answer 23

I'm going for A

Answer 24

no its not A

\(\color{red}4 ~times ~\color{blueviolet}{sum~of~\color{green}2~and~\color{green}y}\)

1st we sum up \(2\) and \(y\)
then you have to multiply it all by \(4\)

Answer 25

so it B???
and don't say I'm guessing all the time

Answer 26

lol okay
yea its B :)

Answer 27

Which expressions are equivalent to 2(2x + 4y + x − 2y)?

2(x + 6y) and 2x + 12y
2(x + 2y) and 2x + 4y
2(3x + 2y) and 6x + 4y
2(3x + 6y) and 6x + 12y
