Please tell me which one are positive and negative
Karo-lina-s [1.5K]

Answer:

Negative, Positive, Negative, Positive

Step-by-step explanation:

1. 18.75 + (-19)

Adding a negative is the same as subtracting. 18.75 - 19 is -0.25 so the first answer is negative.

2. -3 \frac{7}{10} + 3\frac{4}{5}

If you convert the fraction in the second term to one with the same denominator (three and 8 10ths), you can see that since 8 tenths is more than 7 tenths, the equation will result in positive 1/10

3. 9.4 + (-9\frac{3}{5})

3/5 is the same as 6/10 or .60

9.6 is more than 9.4, so the negative is further from zero than the positive.

4. -7 + 7 + 1/2

-7 + 7 is zero. zero + 1/2 is positive 1/2

Solve for x, find the simplified radical & decimal
Ronch [10]

Answer:

x = 6\sqrt{2} = 8.485

Step-by-step explanation:

In a 45-45-90 triangle, the hypotenuse is \sqrt{2} times the length of a leg.

So, if you are given the hypotenuse, then divide its length by \sqrt{2}

x = 12/\sqrt{2} = 12\sqrt{2}/2 = 6\sqrt{2} = 8.485
