Answer:
2x + 4y = 110
Step-by-step explanation:
Let
The quantity of small tables = x
The quantity of large tables = y
The smaller tables can fit 2 people, the larger tables can seat 4 people.
Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.
Number of people×quantity (small table) + number of people×quantity (large table) = 110
2x + 4y = 110
Answer:
9 mph = the speed in still water
Step-by-step explanation:
Let r = the speed in still water
Then the speed going down stream is r + 3
and the speed going upstream is r - 3
d = rt or t = d/r
time going downstream is 16/(r + 3) and time going upstream is 16/(r - 3)
The total time was 4 hours, so
Multiply thru the equation by (r + 3)(r - 3)
Then 16(r - 3) + 16(r + 3) = 4(r + 3)(r - 3)
16r - 48 + 16r + 48 = - 36
- 36 = 32r
- 32r - 36 = 0
4(r - 9)(r + 1) = 0
r = 9 or -1
But a rate of speed cannot be negative, so x ≠ -1
So, r = 9 mph = the speed in still water
Answer:
I'll help you! Answer is <u>3/2</u>. It's Friday so most people aren't on Brainly doing homework lol
Step-by-step explanation:
The heaviest bag (far right) weighs 4.75 lbs, whereas the lightest bag (far left) weighs 3.25 lbs. As mixed numbers, these would be and . To find how much heavier the 4.75 lb bag is, you must subtract the 2 numbers.
<h3>Step 1. Convert each to a complex fraction</h3>
=
- Numerator = (4 x 4) + 3 = 19
- Denominator = 4 (stays the same)
=
- Numerator = (3 x 4) + 1 = 13
- Denominator = 4 (stays the same)
<h3>Step 2. Subtract fractions like normal </h3>
<h3><u>Final answer: 3/2</u> <u>(</u>Hope this helps!)</h3>
