Answer:

His estimate is reasonable

Step-by-step explanation:

1/10 + 6/10 = 7/10, which can be rounded to 1

1/10, 2/10, 3/10, 4/10, 5/10, 6/10, 7/10, 8/10, 9/10, 1

As you can see, 7/10 is very close to 1.

Answer:

So all the possible solutions are:

$\bold{523,~400,~379~and,~378.6}$

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Add 78 to both sides:

$78+78=$ Cancels Out

$300+78=378$

So now we know the real answer, but it ask for all possible answers.

(Means anything larger than 300 when you plug it into x - 78 > 300.)

Numbers that are greater than 378:

1.) $377-78=299 > 300$ (False)

2.) $523-78=445>300$ (True)

3.) $0-78=-78>300$ (False)

4.) $-62-78=-140>300$ (False)

5.) $400-78=322>300$ (True)

6.) $379-78=301>300$ (True)

7.) $222-78=144>300$ (False)

8.) $378.6-78=300.6>300$ (True)

Answer:

Step-by-step explanation:

35 is exactly 152 but since its asking for greater then you're right it is 36.

But since it says '>' it means not equal to so it would be:

x > 35

x ≥ 36
