4x + 3y = 17 and 5x – 3y = 1
–5m + 6n = –8 and –5m + 8n = 6
2x – 7y = –9 and 6x + 7y = 57
5p – 4q = 3 and –5p – 4q = 13
6c + d = 12 and c – d = 2

Equation:4x+3y=17

x=-3/4y+17/4

y=-4/3x+17/3

Equation:5x-3y=1

x=3/5y+1/5

y=5/3x+-1/3

Equation:–5m + 6n = –8

m=6/5n+8/5

n=5/6m+-4/3

Equation:–5m + 8n = 6

m=8/5n+-6/5

n=5/8m+3/4

Equation:2x – 7y = –9

x=7/2y+-9/2

y=2/7x+9/7

Equation:6x + 7y = 57

x=-7/6y+19/2

y=-6/7x+57/7

Equation:5p – 4q = 3

p=4/5q+3/5

q=5/4p+-3/4

Equation:–5p – 4q = 13

p=-4/5q+-13/5

q=-5/4p+-13/4

Equation:6c + d = 12

c=-1/6d+2

d=-6c+12

Equation: c – d = 2

c=d+2

d=c-2

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.

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
