Step-by-step explanation:
First of all their is an easier way solving this 2l/ + l^2
but how you need it is c because the base is 100 and each face is 40 how 10x8=80 80/2=40
Answer:
replace one question with itself where the same quantity is added to both sides and yes
Step-by-step explanation:
The other answer is wrong :)
Answer:
x + y <u>></u> 15
10x + 5y <u><</u> 100
we will put it in terms of y
y <u>></u> 15 - x
and
5y <u><</u> 100 - 10x
y <u><</u> 20 - 2x

Simple form of the equation y= ax+b
y= (1/7)x + 12
come from 2 equation :
22= 70 a + b
27= 105 a + b
