Which answer choice contains only equations?
a.2+h=14 and k-25=2
b. c-14 and d+134
c.10=3+s and 22-y
d.15+x and 55=r-1

Option A

Step-by-step explanation:

This is the answer because it is the only thing with only equations...

(ex. 25+7=32 and 34+7=41) those are ONLY equations

I hope that this helped you, have an amazing day

The answer is A

Step-by-step explanation: Just took the quiz!!!

answer: 10 meter

step-by-step explanation:

need details

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.
