2r - 18 < = 5r + 3

Subtract both side by 3

2r - 18 - 3 <= 5r +3 - 3

Simplify

2r - 21 <= 5r

Subtract both side by 2r

2r - 2r - 21 <= 5r - 2r

Simplify

-21 <= 3r

Divide both side by 3

-21 ÷ 3 <= 3r ÷ 3

Simplify

-7 <= r

cookies he will need?

Answers

He would need 5 packs of cupcakes which would be 60 cupcakes and we would need 6 packs of cookies to also have 60
Yeah 5 packs for cupcakes for 60 and then 6 for cookies for 60 because 5 times 12 = 60 and 6x10 =60

Which number would make this number sentence true?
12 - (-3) =
A. -9
B. 9

Answers

Answer: 15

Step-by-step explanation: Take 12 and change the -3 to a regular 3.

(12 + 3 = 15.)

Whichever number in the question that’s bigger determines what integer it will have.

C)15 cuz
(-) and (-) = (+)
(-) and (+)= (-)
(+) and (+)= (+)
(+) and (-)= (-)
So 12-(-3)= u can see the - and - so it’s gonna be a plus, so it converts into 12+3.. so you get 15

Name a fraction that is equivalent to three twelfths and also has a denominator that is less than 12. Explain how you found your answer.

Answers

5: six twelfths is one half

6: eight tenths is four fifths

7: four eighths is one half

8: ten tenths is two halves

9: two sixths is one third

10: one quarter, because you divide the top and bottom number by 3

method:

take the first one - four eighths, which is 4/8

the question gives you what to divide them by, 4, so u divide both the top number and bottom number to get 1/2, which is one half :)

Dividing by 6 - six twelfths(6/12) = 1/2(one half)

Dividing by 2-  eight tenths(8/10) = 4/5( four fifth)

Dividing by 4 - four eighths(4/8) = 1/2 (one half)

Dividing by 5- ten tenths(10/10) = 1 = two halves(2/2) =1

Dividing by 2 -two sixths(2/6) = 1/3(one third)

The fraction that is equivalent to three twelfths(3/12) and also has a denominator that is less than 12 is one quarter(1/4).What is Division?

Write an Equation and solve for x.

Answers

Answer:

x = 17

Step-by-step explanation:

The angles 3x + 1 and 4 + 2x MUST total 90 degrees:

5x + 5 = 90 degrees

or:  5x = 85 degrees

therefore:  x = 17

Answer:

x=17

Step-by-step explanation:

(3x+1)+(4+2x)=90

3x+1+4+2x=90

5x+5=90

5x + 5 - 5 = 90 - 5

5x = 85

5x/5 = 85/5

x = 17
