Henry is mixing concrete. To make concrete he needs to mix cement, sand and gravel in the ratio 3:2:7 by weight.
Henry needs to make 180kg of concrete.
He has 46kg of cement, 29kg of sand and 105kg of gravel.
Which ingredient is Henry short of?

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

the answer is 0.3175 hope that you ^w^
