Slove this inequality 3b-7 less the 20

Answers

Answer 1

Answer:

Hi friend

#24

y/9+5=0

Simplify to both sides

1/9 y+5=0

Now subtract 5 from both sides

1/9 y+5-5=0-5

1/9 y=-5

Multiply both sides by 9 so we can find the y value

9(1/9 y)= (9)(-5)

y=-45

The answer is A ( Your answer was not good)

#25

3b-7<32

First you need to add 7 to both sides

3b-7+7=32+7

3b<39

Now divide both sides by 3 so we can find the value for b

3b/3<39/3

b<13

The answer is A

#26

3p-16<20

Now we gonna do the same thing

Add 16 to both sides

3p-16+16<20+16

3p<36

Now divide both sides by 3

3p/3<36/3

p<12

The answer is C

#27

3p-6>21

Just do the same thing

Add 6 to both sides

3p-6+6>21+6

3p>27

Divide both sides by 3

3p/3>27/3

p>9

The answer is B

I really hope that's help and good luck :0

At a candy store, Erika bought 3 kilograms of cinnamon red hots and 1 kilogram of gummy bears for $21.00. Meanwhile, Irene bought 3 kilograms of cinnamon red hots and 3 kilograms of gummy bears for $39.00. What is the cost of one kilogram of each type of candy?

Answers

Taking the difference of the both you can see that 2 kg of gummy bears would cost $18. So each kg of gummy bear is $9. Now subtract $9 from what Erika bought, and 3 kg of red hots are $12. So each kg of red hots are $4.

Mark Brainiest Answer plz.

Is the permeter of a pentagon five times the length of one side? why or why not

Answers

If it's a REGULAR pentagon ... all sides the same length ... then yes,
because all 5 sides of any pentagon form the whole outline for the
perimeter.

But if it's not a regular pentagon, then the sides have different lengths.
You might get lucky, and pick one side that happens to be 1/5 of the
perimeter, but that would just be blind luck. For an irregular pentagon,
you can't say that the perimeter is five times the length of any one side.

Answer:

Yes

Step-by-step explanation:

Rearrange the formula a2 + b2 = c2 for a. A) a = (c2 − b2)2 B) a = (c2 + b2)2 C) a = c2 − b2 D) a = c2 + b2

Answers

Answer:

the correct answer is:

a = √c^2 − b^2

Step-by-step explanation:

a^2 + b^2 = c^2

Explanation:

a^2 + b^2 = c^2

a^2 = c^2 − b^2

a = √c^2 − b^2

Answer:

C2 + a2 +2 = b
