Answer:
<h2>d = 8</h2><h2>g = 2</h2>
Step-by-step explanation:
8d + 4 = 5d + 28
Group like terms
That's
8d - 5d = 28 - 4
3d = 24
Divide both sides by 3
d = 8
Cross multiply
we have
7(7g + 8) = 38.5(4)
49g + 56 = 154
49g = 154 - 56
49g = 98
Divide both sides by 49
g = 2

33.87 and 33.42 have a difference of 0.45
Answer:
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:
3 1/4
Step-by-step explanation:
3/4 + (1/3 ÷1/6) - (-1/2)
Subtracting a negative is adding
3/4 + (1/3 ÷1/6) +1/2
Parentheses first
Copy dot flip
3/4 + (1/3 * 6/1) +1/2
3/4 + 2 + 1/2
Get a common denominator
3/4 + 2 + 2/4
2 + 5/4
2 + 4/4 +1/4
2+1 + 1/4
3 1/4
