Answer: 28.1x−3.1
Step-by-step explanation: 1.5(x+3)+3.8(7x−2)
=(1.5)(x)+(1.5)(3)+(3.8)(7x)+(3.8)(−2)
=1.5x+4.5+26.6x+−7.6
=(1.5x+26.6x)+(4.5+−7.6)
=28.1x+−3.1
=28.1x−3.1

Answer:
Tessa receives £60
Step-by-step explanation:
The ratio is 5:3 so 5+3=8 which is then what you use to divide 96
96/8=12
12x5(the 5 comes from the ratio for Tess) is 60 therefore she receives £60
Answer:
y = 0.375x
Step-by-step explanation:
Let there are two variables, one independent variable x and another dependent variable y which are in proportionality relation.
So, y ∝ x
⇒ y = kx ........... (1) {Where k is the proportionality constant}
Let us assume that the given values of 4 and 1.50 are values of x and y respectively.
Hence, from equation (1) we get, 1.5 = 4k
⇒ k = 0.375
So, the proportionality equation is y = 0.375x (Answer)
