Answer:
Yes, Amanda has enough materials to make the concrete mix.
Step-by-step explanation:
Total units = 1+3+5
= 9
9 units = 630kg
1 unit = 630kg ÷ 9
= 70kg (Less than 80kg of cement, more than enough)
3 units = 3 × 70kg
= 210kg (Less than 215kg of sand, more than enough sand)
5 units = 5 × 70kg
= 350kg (Less than 370kg of gravel, more than enough gravel)
4x + 2 < 14
4x < 14 - 2
4x < 12
x < 12/4
x < 3
S = { x <3 }
X=5/2,x=2
i cant explain it but if you got to symbolab.com and input the equation it will solve and show you the steps
Your number would be 10 and the exponet would be 6
