1 L = 1000 ml so you can do from 4 L you can do 4000 / 150 = 26,66 (after rounding it to its tenth) beakers.
1 g = 1000 mg so you'd need to take 1000 / 500 = 2 pills.
Again, 1 g = 2000 mg so 2,000 = 2 g of sodum.
<em><u>Part B (Taxi):</u></em>
12 miles = 0.5 miles + (115×0.1) miles
Rate: $2.40 + (115×0.20)
= $25.40
Total cost (with tip): $25.40 + $2
= $27.40
20 miles = 0.5 miles + (195×0.1) miles
Rate: $2.40 + (195×0.20)
= $41.40
Total cost (with tip): $41.40 + $2
= $43.40
50 miles = 0.5 miles + (495×0.1) miles
Rate: $2.40 + (495×0.20)
= $101.40
Total cost (with tip): $101.40 + $2
= $103.40
<em><u>Part B (Uber):</u></em>
12 miles (rate) = $1 + ($1.05×12)
= $13.60
Total cost (with tip): $13.60 + $2
= $15.60
20 miles (rate) = $1 + ($1.05×20)
= $22
Total cost (with tip): $22 + $2
= $24
50 miles (rate) = $1 + ($1.05×50)
= $53.50
Total cost (with tip): $53.50 + $2
= $55.50
<em><u>Part C</u></em>
Uber is a better mode of transportation. This is because given the same distance travelled for both the taxi and the Uber, Uber has a lower cost compared to the taxi.
X= largest integer
X-1=next integer
X-2=lowest integer x + x-1 + x-2 = 267
3x-3=267
3x=267+3
3x=270
X=270÷3
X=90
Now substitute x + x-1 + x-2 = 267
90+ (90-1)+(90-2)=267
90+89+88=267 So largest integer is 90
Answer:
Arlo's weight = 52.3 kg
Explanation:
Let Arlo be "x"
Then,
Arlo = x
Bert = x+20 (Because Bert is 20 heavier than Arlo)
Cassie = x+20-5 (Because Cassie is 5 lighter than Bert)
Donnie = 
(Because Donnie is half of Bert's weight)
Average = 57
Step by step Calculations:
57 = 
(The whole divided by 4 because the total people is 4)
57*4 = x + x + 20 + x + 20 - 5 +
228 = 3x + 35 +
228 - 3x - 35 =
193 -3x =
2(193 - 3x) = x + 20
386 - 6x = x + 20
386 - 20 = x + 6x
366 = 7x
x = 
x = 52.3 kg (corrected to 3 significant figures)
Therefore Arlo's weight is 52.3 kg
the answer would be x=6
to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent
hope this helps :)
