<h3>Explanation:</h3>

Given:

total score is 63
field goals score 3
touchdowns score 7

Find:

a linear equation representing the relationships given
a graph of that equation
combinations of field goals and touchdowns that give the score

Solution:

1. see above for what is given

2. <em>Touchdowns and field goals can be represented by variables</em>. In the attachment, field goals are represented by x, and touchdowns are represented by y.

The score value of a field goal is 3, so the total score from x field goals can be written as the term 3x.

Likewise, the total score from y touchdowns can be written as the term 7y.

The equation of interest is then ...

3x + 7y = 63

The graph of it, and its integer solutions, is attached.

Possible combinations of (field goals, touchdowns) are ...

(0, 9), (7, 6), (14, 3), (21, 0)

Susan is celebrating her birthday by going out to eat at five guy's for burgers. If the bill in $40 and she wants to leave a tip

damaskus [11]

Answer:

Step-by-step explanation:

Susan can easily figure the tip by the following procedure. 10% of the bill is the amount with the decimal point moved one place to the left, so is $4.00. 5% of the bill is half that, or $2.00.

15% of the bill is 10% + 5%, so is $4.00 +2.00 = $6.00. The tip will be $6.00.

Answer:

24: x = 31

25: x = 15

Step-by-step explanation:

Remark

24 is supplementary which means that the two angles add to 180o which is on the right hand side of the equation

25 is complementary which means that the two angles add to 90o which is on the left hand side of the equation

Twenty Four

3x + 31 +2x - 6 = 180 Collect the like terms

3x +2x + 31 - 6 = 180 Do the adding and subtracting.

5x + 25 = 180 Subtract 25 from both sides

5x + 25 - 25 = 180 - 25

5x = 155 Divide by 5

x = 155/5

x = 31

Check

3x + 31 = 3*31 + 31

3x + 31 = 93 + 31

3x + 31 = 124

2x - 6 = 2*31 - 6 = 62 - 6 = 56

Total 124 + 56 = 180 as it should.

Twenty Five

Equation

3x+ 4x - 15 = 90

Solution

7x - 15 = 90 Like terms have been collected on the left.

7x = 90 + 15 15 was added to both sides

7x = 105 Divide by 7

x = 15 I'll leave the check to you

Luda [366]

Answer:

$42.26

Tom spent more on tax ($1.54 vs his cousin's $0.72)

Step-by-step explanation:

Tom: $22 x 1.07 = $23.54

tax spent = 22 x 0.07 = $1.54

Cousin: $18 x 1.04 = $18.72

tax spent = 18 x 0.04 = $0.72

Total= $23.54 + $18.72 = $42.26
