Which method represents a correct way to solve the inequality 4-2x<6

1 answer:

4 0

First subtract 4 from btoh sides of the equation
4 - 4 - 2x < 6-4
-2x < 2
Now divide both sides by -2
x > -1

NOTE: when dividing by a negative as above the inequality sign is flipped.

One month,ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as ruby. Together they worked 126 hours

Misha Larkins [42]

I + 6 = r

4r = s

i + r + s = 126

4i + 24 = 4r

s= 4r

i = r-6

4i+24=i+6
-3i=18

i = 6

What is a real world provlem tjat involves dividing a decimal by a whole number?

Alina [70]

Money makes for nice decimal examples.

If you had $1.50, and you wanted to split it among three people, you would have :

1.50 divided by 3 (which would be $0.50 each)

Diego's sister is twice his age minus 9 years. She is also as old as half the sum of the ages of Diego and both of his 12-year-o

slava [35]

Answer:

Diego is 14 years old.

Sister is 19

Step-by-step explanation:

x = Diego's age

x + 24

2x-9 = 2

First to get rid of the fraction we multiply each side by 2

2(2x-9) = 2((x+24)/2)

4x-18 = x+24

The we isolate x

4x-18 = x+24

-x+18 -x+18

3x = 42 Now we divide each side 3

3 3

x = 14

So Diego is 14

Now we can solve for his sister. We can use one of the two equations from earlier to do this.

Plug 14 in for x and then solve for his sister

2(14)-9

28-9

His sister is 19

Describe how you can use the make a ten strategy to find the sum 7+9

kondor19780726 [428]

I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
