Can someone help me <br><br> 1.3x-338
Olegator [25]

Answer:

Equivalent expressions are expressions which are equal. This means they simplify to the same expression. Simplify the two expressions -1.3x - (-8.9x) = 7.6x and -1.3 + (-8.9X) = -10.2x.

Then simplify each option to determine if it is equal -1.3x - (-8.9x), -1.3 + (-8.9X) or neither:

−1.3x−8.9x  = -10.2x. This is equivalent to  -1.3 + (-8.9X) .

8.9x+(−1.3x)  = 7.6x This is equivalent to  -1.3x - (-8.9x) .

−8.9x+(−1.3x)  = -10.2x This is equivalent to  -1.3 + (-8.9X) .

8.9x−(−1.3x)  = 10.2x Neither

−1.3x+8.9x  = 7.6x This is equivalent to  -1.3x - (-8.9x)  .

−8.9x+1.3x = -7.6x Neither

Thanks for your help!
yan [13]

a and b are the two leg sides

c is the longest side.

a^2+b^2=c^2

a=x

b=9

c=11

a=c-b

11 squared is 121

9 squared is 81

121-81=40

The square root of 40, rounded to the nearest hundredth, is 6.32

What is the ratio of rolling a 2 to rolling a 5?
soldi70 [24.7K]

Answer:

when we have two dice, the odds are not as simple. For example, there's only one way to roll a two (snake eyes), but there's a lot of ways to roll a seven (1+6, 2+5, 3+4).
