2.75 cups of water mixed with 3.5 cups of pancake mix will make 19 pancakes. How much water is needed if there is only 1.5 cups of pancake mix left?

1 5/28 cups of water

Step-by-step explanation:

Water : pancake mix

2.75 : 3.5

X : 1.5

2.75/X = 3.5/1.5

X = 2.75 × 1.5/3.5

X = 33/28 or 1 5/28 cups

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

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

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

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

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
