Answer:
or 
Step-by-step explanation:
4x + 15 < 40
Subtract 15 from both sides
4x + 15 - 15 < 40 - 15
4x < 25
Divide both sides by 4
4x/4 < 25/4
x < 6.25
or
x < 6 1/4
2x2x2x2x2x2= 64
4x16= 64
8x8= 64

Answer:
8 weeks
Step-by-step explanation:
Given data
Matteo
Amount= $400
Spending per week= $10
Hence his balance after x weeks is given as
y=400-10x-------------1
Luca
Amount= $200
Spending per week= $15
Hence his balance after x weeks is given as
y=200+15x-------------2
Equate 1 and 2
400-10x=200+15x
collect like terms
400-200=15x+10x
200=25x
x= 200/25
x= 8 weeks
Hence it will take 8 weeks
