3(q−7)=27 need help plzz 1st peep gets brainlest
ANTONII [103]

━━━━━━━☆☆━━━━━━━

▹ Answer

<em>q = 16</em>

▹ Step-by-Step Explanation

3(q - 7) = 27

3q - 21 = 27

Add 21 to both sides:

21 + 21 = na

27 + 21 = 48

3q = 48

Divide both sides by 3:

3/3 = q

48/3 = 16

q = 16

Hope this helps!

Answer: 5-2x=6-x, x= -1/3

Explanation:

“When I double it and subtract it from five it is the same as subtracting it from six”

So double means multiply by two, and the same as means equal. Use a variable to represent the number.

Therefore your equation is:
5-2x=6-x

So solving the equation would be:
-2x-x = 6-5
-3x = 1
x= -1/3

Amy can paint a room in 12 hours. Alicia can paint the same room in 16 hours. How long does it take for both Amy and Alicia to p
Simora [160]
Well 12 is 3\4 of 16 so honestly it would take the 8 hours working together.

As far as formula if I had to guess it would look like.. 12Amy(Ay)- 16Alicia(Aa) = 4 hours minus 4 from Amy would be 8hours.

in fraction form might make more sense. 3\4 - 4\4 = 1/4 minus that from Amy and she'll finish together with Alicia 4 hours quicker being 8hours.
