Answer:
3cm
Step-by-step explanation:
volume of cuboid =length × base × height
so height will be
volume divided length ×base
v=60cm^3
lenght=5cm
base=4cm
h= 60 ÷(5×4)
h= 60÷20
h= 3cm
remember that cm^3 will cancel one time with 5cm and second time 4cm and leave you with cm

Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
