What is the value of 6 r + 6 − 4 s , when r = 7 and s = 3 ?

36

Step-by-step explanation:

6r + 6 - 4s

r = 7

s = 3

6(7) + 6 - 4(3)

42 + 6 - 12

(remember PEMDAS, adding/subtracting left to right)

48 - 12 = 36

therefore the answer is 36

hope this helps ! :)

Hey there!

6r + 6 - 4s

If r = 7 & s = 3, then SUBSTITUTE it into the EQUATION

6(7) + 6 - 4(3)

6(7) = 42

42 + 6 - 4(3)

42 + 6 = 48

48 - 4(3)

4(3) = 12

48 - 12

= 36

36

Good luck on your assignment and enjoy your day!

the answer is ! ?

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
