Elimination 18x+27y=7.5 4x+6y=20

so this equation has no solution.

Step-by-step explanation:

18 x + 27 y = 7.5 .......equ No  1

4 x + 6 y = 20........equ No 2

4 x = 20 - 6 y

x =

substitute the value of x in equ No 1108 y

18 { }  + 27 y = 7.5

18( 20 - 6y) + 27 y × 4 = 7.5 × 4

18 × 20 - 18 × 6 y +27 × 4 y =30

360 - 108 y + 108 y = 30

360 - 0 y = 30

330= 0 y

y = 330 ÷ 0 cannot be defined

so we cannot find x also .

so this equation has no solution.

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
