Question

ILL FAN AND GIVE A MEDAL, FOR HELP..
the picture of the problem will be below...

Answer 1

anyone?

Answer 2

It would be the first line. 4 less than a number divided by 3 would mean x / 3 - 4, not x / 3 + 4

Answer 3

A number divided by 3 is 4 more than -11. So, x / 3 = 4 + -11
x / 3 = -7
x = -21

Answer 4

If you see an 'is', you can just replace with an = sign normally.

Answer 5

thank you :)

Answer 6

did you get the image I just sent?

Answer 7

Yes

Answer 8

okay, what is the answer to it? and can you help me with some more aftert that?

Answer 9

Since there's no statement, I assume the first line is correct.
The error is with line 5. -8 - 4 is -12, not -4 which is -8 + 4

Answer 10

Identify the solution set of the inequality, using the given replacement set.



x < –4; {–10, –4.3, –4, –3.9, 2, 6.5}









A.

{–10, –4.3, –4}








B.

{–4, –3.9, 2}








C.

{–10, –4.3}








D.

{–3.9, 2}

Answer 11

Solve.

8y – 24 > –16









A.

y > –5








B.

y > –1








C.

y > 1








D.

y > 5

Answer 12

The first one would be C. A = {–10, –4.3, –4} is not valid as x < -4, which means -4 is not inclusive. B and D are out because x cannot be 2 which is more than -4.

Answer 13

what about the rest of the questions?

Answer 14

8y - 24 > -16
For linear inequality, solve it as if the inequality is an equal sign.
8y - 24 > -16
8y - 24 + 24 > -16 + 24
8y > 8
8y / 8 > 8 / 8
y > 1
So, the answer is C

Answer 15

and the other questions? (their are 5 on the quizso that leaves 3 more left)

Answer 16

-t / 5 >= 15
Likewise, with this question, except for one special rule. If you change the sign of the expressions in inequality questions, you need to flip the inequality sign as well.
-t / 5 * 5 >= 15 * 5
-t >= 75
t <= -75
Notice that the >= is flipped to <=, because the sign on t and 75 is changed.

Answer 17

what about this one?

Answer 18

An opened circle on the number line means exclusive. So, just count backwards and you will see that the circle is on -7. The red line extends to the right so y would be bigger than some value, which is -7. y > -7 or y + 5 > -7 + 5 -> y + 5 > -2.

Answer 19

a b c or d?

Answer 20

-s / 2 >= 9
-s / 2 * 2 >= 9 * 2
-s >= 18
s <= -18
Notice that the sign got changed again. Now see that the sign is lesser or equal to, so the circle would be a closed circle. Furthermore, the red line will be extending to the left, because of <. So, the answer would be A.

Answer 21

For question 3, the answer is A

Answer 22

what about this one?

Answer 23

The explanation for question 3 is above

Answer 24

what about question 5?

Answer 25

Also A

Answer 26

Which expression is equivalent to this one?

–5(6 + 11)









A.

(–5) · 6 + 11








B.
(–5) + 6 + 11







C.

(–5) · 6 · 11








D.

(–5) · 6 + (–5) · 11

Answer 27

Which expression is equivalent to this one?

k · 6 + k · s









A.

6(k + s)








B.

s(6 + k)








C.

k(6 + s)








D.

k · (6 + k) · s

Answer 28

What is the solution to the equation?



5(8 + 7) = 5 • x + 5 • 7









A.

x = 1








B.

x = 5








C.

x = 7








D.

x = 8

Answer 29

-5(6 + 11).
By the distributive law, the -5 is distributed to the 6 and 11. So, -5(6 + 11) = -5 * 6 + -5 * 11 which is D.

Answer 30

thank you

Answer 31

what about the one that is this k · 6 + k · s
?

Answer 32

k * 6 + k * s
This time, you just need to think in reverse or factor it.
k(6 + s) which is C

Answer 33

5(8 + 7) = 5 • x + 5 • 7

Answer 34

5(8 + 7) = 5 • x + 5 • 7
5 * x + 5 * 7 is the same as the previous question, 5(x + 7)
By comparing both sides, 5(8 + 7) = 5(x + 7), so x = 8

Answer 35

D would be the answer

Answer 36

what about this one?

Answer 37

What is the solution to the equation?

12y + 6 = –18









A.

y = –2








B.

y = –1








C.

y = 1








D.

y = 2

Answer 38

7x + 6 = -22
7x + 6 - 6 = -22 - 6
7x = -28
7x / 7 = -28 / 7
x = -4
B
I hope you understand how I got the answer

Answer 39

Try 12y + 6 = –18 on your own first. If you need help understanding, just ask

Answer 40

okay

Answer 41

I don't understand how to do it

Answer 42

...
12y + 6 = -18
You want y to be alone, so you have to get rid of the 12 and 6.
To get rid of the 6, you need to subtract 6 from the left hand side of the equation. But, any operation you do to one side must be applied to the other side. So
12y + 6 - 6 = -18 - 6
6 - 6 = 0 and -18 - 6 = -24
12y + 0 = -24
Anything added to 0 is itself.
12y = -24
Now, you have to remove the 12. However, this time, you can't add or subtract 12. Instead, you have to divide by 12 on both sides because any operations must be applied to both sides.
12y / 12 = -24 / 12
12 / 12 = 1 and -24 / 12 = -2
1 * y = -2
Anything multipled by 1 is itself.
y = -2
A

Answer 43

thank you, let me write it down so ill know how to do it

Answer 44

how do you do division ones?

Answer 45

anything divided by itself is 1
12 / 12 = 1
for the -24, you factor out a 2 to get -2(12).
-24 / 12 = -2(12) /12
Notice the 12 / 12? It equals to 1.
So, -2(12) /12 = -2 * 1 = -2

Answer 46

like this one \[2-\frac{ z }{ 3 }=12\]

Answer 47

?

Answer 48

I don't understand how to do the equation I just put.

Answer 49

2 - z / 3 = 12
Now see the negative on z? This time, you add z / 3 to both sides of the equation
2 - z / 3 + z / 3 = 12 + z / 3
2 = 12 + z / 3
Now you got a positive z. Next, remove the 12 by subtracting 12 from both sides
2 - 12 = 12 - 12 + z / 3
-10 = z / 3
Next, get rid of the 3 by multiplying 3 to both sides.
-10 * 3 = z * 3 / 3
-30 = z or z = -30

Answer 50

okay that kind makes sense :) thanks
