Tamara is planting bushes around her house. so far today she has planted 5 bushes and she wants to plant at least 12 bushes today. which inequality can be used to find the number of bushes?

b+5 ≥ 12

Step-by-step explanation:

Let the additional bushes to be planted be represented by a variable b

Since Tamara already planted 5 bushes, 5 will be a constant in the inequality ;

So,

b+5 ≥ 12 will be the inequality used to find number of bushes.

step-by-step explanation:

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.
