Answer:
x= 66
Step-by-step explanation:
if you set up the equation mathematically, it would be x+0.5x=99, because 50% is essentially just 0.5.
so, now that you have the equation, you have to add like terms, so it would be 1x+0.5x=99, and 1+0.5 is 1.5, so youre left with the equation 1.5x=99.
from there, you solve for x by dividing each side by 1.5:
1.5x=99
/1.5 /1.5
x=66
im sorry if this didnt make much sense, but i hope this helped!! :D
Answer:
87.5 ml tube of toothpaste slightly offers the better value of money.
Step-by-step explanation:
In order to know the better value of money, we need to find the volume of each toothpaste for 1p.
For first tube of toothpaste:
87.5 ml costs 49p
Therefore, for 1 p = 87.5/49 = 1.78571429 = 1.8 ml
For second tube of toothpaste:
125 ml costs 72 p
Therefore, for 1 p = 125/72 = 1.73611111 = 1.7 ml
Since, 1.8 ml > 1.7 ml
So, 87.5 ml tube of toothpaste slightly offers the better value of money.
Answer:
(a) k = C + 273.15, F = 1.8(k - 273.15) + 32
(b) k = 296.15
(c) 25 celcius is greater than 300 kelvis.
Step-by-step explanation:
(a) one equation would be to solve for k instead of c, and another related equation could be from kelvin to Farenheit.
C = k - 273.15
C + 273.15 = k
k = C + 273.15
F = 1.8(k - 273.15) + 32
(b) for this one you have to substitute in the previous equation and solve for k.
23 = k - 273.15
k = 23 + 273.15
k = 296.15
(c) you have to convert either kelvins to celcius or celcius to kelvins.
C = k - 273.15
C = 300 - 273.15
C = 26.85
So 25 celcius is greater than 300 kelvis.
