I know that the square root of 49 = 7 since 7 x 7 = 49. But the negative square root of 49 is -7.
Answer:
D. Subtraction property of equality
B. 6.5
Step-by-step explanation:
First blank:
The equation is x + 6.5 = 13.
To solve the equation, you want x alone on the left side, showing "x = some number." Since 6.5 is being added to x, you need to SUBTRACT 6.5. You must do the same operation to both sides of an equation, so you need to SUBTRACT 6.5 from both sides of the equation. What allows you to subtract the same number from both sides of an equation is the
<em>D. Subtraction property of equality </em>
Second blank:
Subtract 6.5 from both sides.
x + 6.5 = 13
x + 6.5 - 6.5 = 13 - 6.5
x = 6.5
<em>Answer: B. 6.5</em>
This inequality has NO SOLUTION:
PROOF:
3x + 1 < 2x - 2 < 5x +7
1st let's analyze the 1st inequality: 3x+1<2x-2
3x-2x <-2-1 Then x <-3
2nd let's analyze the 2nd inequality: 2x-2 < 5x+7
2x-5x < 7+2 Then -3x<9 OR 3x > - 9 and x> - 3
In the 1st we have x <-3 in the 2nd we have x > - 3 which is impossible
