Blake estimated that 130% of 20 is “2.6.” without doing any calculations, explain to blake how you know he is wrong. then after explaining why he is wrong, show the work to estimate correctly.

100 % represents the actual amount. For e.g. 100 % of 10 is 10 .

So 100 % of 20 have to be 20.

And 130% is more then 100%, therefore the value of 130%, should be more then 2.6 .

So 130% of 20 is 2.6 is wrong .

And to find 130% of 20, we just multiply 130 and 20 and divide by 100 which gives 26 .

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

10 you would take 50/ .2
