-2x <-12

solve the inequality

Answers

Answer:

x > 6

Step-by-step explanation:

-2x < -12

divide by -2

switch signs because you're dividing by a negative number

-2x/-2 < -12/-2

x > 6

Hope this helps :)

Answer:

x > 6

Step-by-step explanation:

Solve -2x <-12 for x.  Your answer must be a set of real numbers.

Divide both sides by -2.  Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:

-2x < - 12

-----   ------

 -2      -2

This becomes x > 6, "the solution set"

The Ramirez family has a circular garden with a diameter of 22 feet. They cover the garden with mulch. The cost of mulch is $1.25 per square foot. To the nearest dollar, how much will it cost to cover the garden with mulch. Show your work.

A.$380 B. $475
C. $1.520 D. 1.900

Answers

Answer:

b) $475

Step-by-step explanation:

if it has a diameter of 22 feet, that means it has a radius of 11 feet

the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380

Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475

b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has
a radius of 11 feet
the formula of the area of a circle is Tr?. so
square the radius and you will get 121, multiply
that by TI and you get 380
Now we know the area is 380 square feet, so
multiply that by $1.25 and the answer is $475

(HELPP) twelve people can paint a barn in 15 days. how many days will it take for them to finish the work if each person's productivity is increased by 25%?

Answers

Answer:

11.25 days

Explanation:

15 / 12 = 1.25

1.25 x 0.75 = 0.9275

0.9375 x 12 = 11.25

I suggest you do this
15 times .25 and it will give you how many people you will have. Then you do 15/12 which gives you 1.25 then you multiply how many people you have and 1.25

3.75 x 1.25 = 4.68

4.68 is how many days it would take. Again I’m not sure I haven’t done this in a while
