About 9.38

Step-by-step explanation:

Since the is between the and the which simplified is 9 and 10, you just need to guess and check. Eventually you'll get about 9.38 (I used Google cause I was lazy) And if it isn't between the numbers 9 & 10, it's wrong.

The answer is 2√22.

Step-by-step explanation:

You have to elaborate it by finding the common factors :

88 = 1×88

88 = 2×44

88 = 4×22

88 = 8×11

Next, you have to find the perfect square. In the factors above, 4 is the perfect square then, you can square root it :

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
