Answer:
So roughly c x c = b/100
5 x 5 x 100 = $2500
Step-by-step explanation:
Lets say c = 5 and b = 1
= 5c =100c/5c x b
= 20c x b
We can also show
= 20c x b =5c
c = 20c/5c x b = 5c
1/20 x 5c = 5c
b=1
One example is 20% = 0.20 x 500 = 100c
= 7.12c = 7c
1= 100%
100 x 71.042 = 710.42 weekly pay. emergency tax 142 = 568
100 x 71.042 = 710.42 weekly pay, normal tax 15% 142.084 =107
710-107 = 603 a week
4.3/7 x 603/7 = 86.1428571429 x 30 = 2584.29
Answer:
x= 50
Step-by-step explanation:
7/x = 14/100
14x = 700
x = 50
the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.
I hope this helped
Answer:
483
Step-by-step explanation:
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
5(2)^3-7/ 4(2)^2 = 5(8) - 7 / 4(4) = 40-7/ 16 = 33/16
1. Substitute 2 in to the places where x are.
2.solve the square root first then multiply whats outside the square root with the numbers. (2)^3 = 8 and (2)^2 = 4, now multply 5 x 8 = 40 and multiply 4 x 4= 16
3. subtract 7 from 40 to get 33.
4. Check if it can be further simplified, this cant so the answer is 33/16
