Inequality task : -3(x+2)>-69-12x

Mathematics
1 answer:
lys-0071 [83]3 years ago
7 0

Answer:

-7 > x

Step-by-step explanation:

first we expand the brackets so it will be -3x -6>-69-12x

then we can convert the > to = so it will be :

-3x -6=-69-12x

we can now try to solve the equation for x so :

-3x -6= -69-12x

-6 = -69-9x

63 =-9x

7 = -x

-7 = x

we can then change the symbols back so it will be:

-7 > x

Ierofanga [76]

Answer:

54, 486, 154

x+9x+100+x= 694

11x=594

x= 54

54×9=486

54+100= 154

54+486+154=694.

Hello people can you please help me on this
snow_lady [41]

Step-by-step explanation:

<u>Step 1:  Complete the first equation</u>

0.1 is a tenth, therefore if we have 15.3 then we have 153 tenths.

Step 2:  Complete the second equation

15.3 / 3 = 5.1  

0.1 is a tenth, therefore if we have 5.1 then we have 51 tenths.  

<u>Step 3:  Complete the third equation</u>

15.3 / 3 = 5.1

Jacob has $200 to spend on STAR WARS toys. He already purchased $75 on vehicles and new action figures will cost him $8 each. Ho
just olya [345]

Answer:

15 action figures

Step-by-step explanation:

Jacob had $200 to start off with. He spent $75 on vehicles, so we are going to subtract $75 from $200

200 - 75 = 125

He had $125 left. From the money he has left, he wants to purchase more toys. Action figures are $8 each. We will need to find how many action figures he can buy with the rest of his money. To do that, we will divide $125 by $8

125/8 = 15.625

He can buy 15 action figures with his remaining money. He will have remaining change.

I think the equation is:

8x + 125 = 200

8 gets the variable, 200 is the total, and 125 will not get the variable.
