5p-30 is the simplification to this rather simple equation.
Answer:
x= 6.85 or 89/13
Step-by-step explanation:
perimeter is sum of all sides added, so add them all and set them equal to 84
4(x-3) + 3x - 1 + 6x + 8 = 84
distribute
4x + 12 + 3x - 1 + 6x + 8 = 84
combine like terms
13x - 5 = 84
solve for x
x = 89/13 = 6.85
a bus took 30
minutes-------------------------- to cover a distance of 20 city blocks<span>
X
minutes------------------------------------------------one (1) city block</span>
I apply a rule of three
<span>
X=(1)*(30)/20=1.5 </span>
Therefore
the bus moved
1.5 minutes/block city

5 inch is the width, 8 inch is the length.
Find to scale between the two widths:
10 /5 = 2 the larger photo is 2 times larger,
Multiply the known length by 2:
8 x 2 = 16
The length would be 16
Answer:
She will get <u>80mg</u> of dextromethorphan and <u>800mg</u> of guaifenesin. And the bottle last for <u>6 days</u> approximately.
Step-by-step explanation:
Given that the Robitussin DM contains dextromethorphan 10mg/5mL and gualfenesin 100mg/5mL. And we are also given that Mrs Smith took four doses and each dose is 2 teaspoons=2X5=10mL.
So, four doses=4X10=40mL.
So, dextromethorphan in 4 doses is = 
And Guaifenesin in 4 doses is = 
Dosage of medicine daily she has to take=40mL and the bottle contains 237 mL. Hence the number of days bottle last = 
≈6 days approximately.
