Answers:


1) -3(x + 8) = -21

2) Division Property of Equality

3) x + 8 = 7

4) Subtraction Property of Equality


Reasoning:


You are already given the equation, so that will be #1 in the Given.

#2 shows both sides being divided by -3, so you will put the Division Property of Equality.

#3 shows the Division Property after it is carried out, so you will put the equation after the division is done.

#4 shows you are subtracting 8 from both sides, so put the Subtraction Property of Equality.

Amelia and Barrett sold a total of 137 raffle tickets at the football game. Barrett sold 10 fewer than twice as many as Amelia.
gtnhenbr [62]

Answer:

Barett Sold 88 Tickets

Step-by-step explanation:

To Start off we are told that the Total of tickets sold between Amelia (A) and Barrett (B) was 137.

Total = 137

Since Barett Sold 10 less than twice as many tickets as Amelia, we can make the following equation, where Barett is B and Amelia is A.

A + B = 137

A + (2A-10) =137   (Barett equalls 10 less than twice Amelia)

Now we can solve the equation for A

A + (2A-10) =137

3A - 10 = 137  (Combine Like Terms)

3A = 147 (add 10 on both sides)

A = 49 (divide by 3 on both sides)

Now that we have the amount of tickets that Amelia sold we can plug it in for B to find out how many tickets Barett Sold

(2A-10) = B

(2*49) - 10 = B

(2A-10) = B

98 - 10 = B

88 = B

What is 3t-7=5, then 6t=
mel-nik [20]
I think the answer is 24t, because 3t is probably 12 and 6t is the double of 3t so the double of 12 is 24..

lana66690 [7]

Answer:

1 13/24 liters

Step-by-step explanation:

To find the answer we have to subtract the liters of water in the bucket from the liters of water in the pail.

3 3/8 - 1 5/6

27/8 - 11/6

change the denominator

3x27/24 - 4x11/24

81/24-44/24

37/24

convert into a mixed number

1 13/24 liters
