Answer:

x >-2

Step-by-step explanation:

We can add 4 to both sides.

Now the equation is -3x<2+4

Simplify to get: -3x<6

Divide by -3 to get x alone

x<-2

Flip the sign since you divided by a negative

x>-2

Answer:

0 and 3 are solution of inequality.

Step-by-step explanation:

Given : -3x – 4 < 2.

To find : Which values are solutions to the inequality.

Solution : We have given

-3x – 4 < 2.

For x = -4 .

-3 ( -4) -4 < 2 .

12 -4< 2.

8 < 2

Which is false statement .

For x = -2 .

-3 ( -2) < 2

6 < 2

This is false statement so, this is not the solution of inequality .

For x = 0 .

3( 0) -4 < 2 .

-4 < 2

We know that negative value is always less than positive .

So, x = 0 is solution of inequality.

For x = 3

-3 ( 3) - 4 < 2

-9 - 4 < 2

-13 < 2

This is also he solution of inequality.

Hence there are two solution 0 ,3.

Therefore, 0 and 3 are solution of inequality.

Anni [7]

Answer:

12.42 = 1242 / 100;

4.6 = 46 / 10;

12.42 ÷ 4.6 = (1242 / 100) ÷ (46 / 10 ) = (1242 / 100) x (10 / 46 ) = ( 1242 / 46 ) x ( 100 / 10 ) = 27 x 10 = 270;

Two liquids Kaylin mixed two liquids for science experiment one container had 7/8 Cup and the other health 9/10 cup what is the

seraphim [82]

Answer:

Step-by-step explanation:

<em>Step 1: Determine quantity per liquid</em>

liquid 1=7/8 cup

liquid 2=9/10 cup

<em>Step 2: Derive expression to calculate total amount of mixture</em>

The expression below can be derived;

T=a+b

where;

T=total amount of mixture

a=total amount of liquid 1

b=total amount of liquid 2

In our case;

a=7/8 cup

b=9/10 cup

replacing;

T=(7/8)+(9/10)=1 31/40 cups

The total amount of mixture=1 31/40 cups

6 pounds of apples and 3 pounds of oranges cost 24 dollars.5 pounds of apples and 4 pounds of oranges cost 23 dollars. Set up a

vitfil [10]

Answer:cost of each pound of apple= $3

And cost of each pound of orange =$2

Step-by-step explanation:

Step 1

Let cost of apples = x

And cost of Oranges =y

Let 6 pounds of apples and 3 pounds of oranges cost 24 dollars be represented as

6 x + 3y= 24----- equation 1

Also, Let 5 pounds of apples and 4 pounds of oranges cost 23 dollars be represented as

5x+ 4y= 23----- equation 2

Step 2

6 x + 3y= 24----- equation 1

5x+ 4y= 23----- equation 2

Using substitution method to solve the equation

6 x + 3y= 24

24-6x=3y

y= 24-6x/3 = 8-2x

Y= 8-2x

Substituting the value of y= 8-2x into equation 2

5x+ 4( 8-2x)= 23

5x+ 32 -8x= 23

32-23= 8x-5x

9=3x

x=9/3

x=3

Putting the value of x= 3 in equation 1 and solving to find y

6 x + 3y= 24

6(3) +3y= 24

18+3y=24

3y= 24-18

3y=6

y=6/3= 2

Therefore the cost of each pound of apple= $3

And cost of each pound of orange =$2
