​

98.64

Step-by-step explanation:

look to the right of the hundredths place

in this case that is to the right of the 4

is the number to the right 5 or greater? then round up the 4 to a 5but if the number to the right of the 4 is less than 5 As in this case, then you leave the 4 as it is.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
