Question

Help. i need to know how to do these for quiz tomorrow.

Answer 1

I'm not sure about all of the questions, but I'll help with what I can.

1. 93 + 96 - (-5) + 92 = 286

93 + 96 = 189

189 - (-5) = 194

194 + 92 = 286

2. 3/4 + 5/6 = 1 7/12

Common denominator: 12

9/12 + 10/12 = 19/12

Simplify: 1 7/12

3. (-9)(3)(-5) = 135

-9 × 3 = -27

-27 × -5 = 135

4. 24/((-4) + 2) × 2 = -6

(-4) + 2 = -2

-2 × 2 = -4

24/-4 = -6

5. z - y + x - IyI (I couldn't find the actual mathematical symbol, so I just used two lowercase L's) use x = 9, y = -6, z = -5

-5 - -6 - l-6l

1 - 6 = -5

z - y + x - IyI = -5

6. -13 + n = -33

-13 + 13 + n = -33 + 13

n = -20

Not sure about 7

8. lv + 7l  = 12

lv + 7 - 7l = 12 - 7

lvl = 5

Not sure about the rest

Hope I was able to help!
