A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Write an equation that represents the situation. Use $x$ to represent the number of roast beef sandwiches. Then determine how many sandwiches the customer buys. Amount Used for Payment $50 Change Received $16.25 An equation that represents this situation is . The customer buys sandwiches.

Number of roast beef sandwiches bought = 5

Step-by-step explanation:

Cost of a roast beef sandwich = $6.75

x = number of roast beef sandwiches bought

Amount Used for Payment = $50

Change Received = $16.25

Actual amount paid = Amount Used for Payment - Change Received

= $50 - $16.25

= $33.75

Actual amount paid = $33.75

Number of roast beef sandwiches bought = Actual amount paid / Cost of a roast beef sandwich

= $33.75 / $6.75

= 5 roast beef sandwiches

Number of roast beef sandwiches bought = 5

answer: 2 and 1

step-by-step explanation: got this question

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
