Answer:
The perimeter is 100 feet. This means that all the sides of the shape must add up to equal 100.
x + x + 5 + x - 3 + x + 4 = 100
4x + 5 - 3 + 4 = 100
4x + 6 = 100
4x = 94
x = 94/4
x = 23.5 feet
Answer: So, your relative takes N tablets each 6 hours. a day has 24 hours, and 24/6 = 4, so he takes N tablets 4 times per day, so he takes 4*N tablets.
each tablet has 200mg, and 2.3 g (or 2300 mg) is toxic.
this means that 4*N*200mg must be less than 2300, if we are seeking for the maximum N possible, then:
4*N*200mg = 2300mg
4*N = 2300/200 = 11.5
N = 11.5/4 = 2.87
if you round up this number, you will end up taking more than 2.3g of tylenol per day, this implies that N must be equal to 2.
So your relative needs to take maximum 2 tablets per day.

Answer:
£191.36
Step-by-step explanation:
Sum the parts of the ratio, 1 + 4 = 5 parts
Divide 320 by 5 to find the value of one part of the ratio.
320 ÷ 5 = 64 ← value of 1 part of the ratio , thus
4 parts = 4 × 64 = 256
Thus he bought 64 first class and 256 second class.
Cost = (64 × £0.67) + (256 × £0.58)
= £42.88 + 148.48
= £191.36
