What is 2.2r +0.47 = 1.79 what is r

r = .6

Step-by-step explanation:

2.2r +0.47 = 1.79

Subtract .47 from both sides

2.2r +0.47- .47 = 1.79 - .47

2.2r = 1.32

Divide by 2.2 on each side

2.2r/2.2 = 1.32/2.2

r =.6

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
