21. what operations would you use in order to solve 3x – 4 = 26. write the operations in the order you would use them

we are given

we are given to solve for x

step-1: Firstly , we will add both sides 4

step-2: now, we divide both sides by 3

so, we get

.............Answer

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
