Is -3.4 greater than or less than -.75

less than.

Step-by-step explanation:

when using negative numbers, the smaller number is the bigger number. So because positive 3.4 is larger than positive 0.75, -0.75 would be larger

Answer with Step-by-step explanation:

It is less then -0.75 because of how it fits on a number line. -0.75 is closer to zero then -3.4 hence -3.4 is less then -0.75.

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
