Answer 1
Answer:

Answer:

$49

Step-by-step explanation:

We have been given that Eric bought lunch for him and his friends at Papa's Pizza. His bill was $50 with tax. If he used a 15% off coupon and then left a 20% tip based on the discounted ticket.

First of all, we will find amount of bill after 15% discount by finding 85% of $50 as:

\text{Bill after 15 percent discount}=\$50* (85)/(100)

\text{Bill after 15 percent discount}=\$50* 0.85

\text{Bill after 15 percent discount}=\$42.5

Amount paid in tip would be 20% of $42.5, so total amount paid after 20% tip would be 42.5 plus 20% of $42.5.

\text{Total amount of bill after tip}=\$42.5+\$42.5* (20)/(100)

\text{Total amount of bill after tip}=\$42.5+\$8.5

\text{Total amount of bill after tip}=\$51

Now, we will subtract $51 from $100 to find amount of change that is \$100-\$51=\$49

Therefore, Eric will get $49 in change.

 
Answer 2
Answer:

Answer:

49

Step-by-step explanation:

50*0.85 (15% off) = 42.5, 42.5*1.20 (20% tip) = 51, 100-51 = 49

Answer:

7/3x  +  2/3 = 7/9x  -  5/6

7/3x  -  7/3x  +  2/3 = 7/9x - 7/3x  -  5/6     (7/9x-7/3x--->7/9x-21/9x---> -14/9x)

2/3= -14/9x - 5/6

2/3+5/6 = -14/9x - 5/6 + 5/6  -  (2/3 + 5/6---> 4/6 + 5/6---> 9/6 ----> 3/2)

3/2 = -14/9x

3/2   /    -14/9  =  -14/9x   /   -14/9 -   (3/2   /   -14/9 ------>  3/2  x  -9/14 ----->

Which linear system has the solution (6, 6)A:4x - 3y = -1 -2x + y = -3
B: x + y = 12 3x - 2y = 6
C: 3x + y = 4 4x - 3y = 1
D: 4x + 3y = 0 2x - y = 0

Answers

B: x+y=12 3x-2y=6
6+6=12 (3×6)-(2×6)=6
By substituting x = 6 and y = 6 into the options we have that the correst answer is option B.

Step-by-step explanation:

Isolate the variable

3p + 4 - 4 = 25 - 4

Simplify

3p = 21

Solve for p

3p/3 = 21/3

Latrell is packing boxes that can contain two types of items. Board games weigh 3 pounds and remote controlled cars weigh 1.5 pounds. The box can hold no more than 25 pounds.Let x represent the number of board games. Let y represent the number of remote controlled cars.



Enter an inequality that represents the situation.

Answers

The correct answer is:

3x + 1.5y ≤ 25

Explanation:

The variable x represents the number of board games.  Each one weighs 3 pounds, which gives us the expression 3x.

The variable y represents the number of remote control cars.  Each one weighs 1.5 pounds, which gives us the expression 1.5y.

The sum of their weights gives us the expression 3x+1.5y.

Since the box can hold no more than 25 pounds, the inequality must be less than or equal to:

3x+1.5y≤25

Answer:

THE ANSWER IS 3x+1.5y ≤  25
