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:
I dont understand it please commet more
Step-by-step explanation:
Two equations are given in the quastion and there are two unknown variables "x" and "y" in them. So solving will not be an issue at all.
Taking the first equation:
5x + 2y = 16
2y = 16 - 5x
y = 8 - (5x/2)
Now putting the value of x found from the first equation in the second equation, we get
-4x + 3y = -2
-4x + 3(8 - 5x/2) = -2
-4x + 24 - 15x/2 = -2
-8x + 48 -15x = -4
-23x = -4 - 48
-23x = -52
x = 52/23
Now putting the value of x in the first equation we get
5x + 2y = 16
5(52/23) + 2y = 16
260/23 + 2y = 16
260 + 46y = 368
46y = 368 - 260
46y = 108
y = 108/46
= 54/23
So the value of x is 52/23 and the value of y is 54/23
