Well, the equation would become 5*10 + 4*-5. (because when a number and a variable are right next to each other, that means they are multiplying). Now all you have to do is solve using the Order of Operations.
5*10+4*-5
50+ 4*-5
50-20
30
You are left with 30 as the correct answer. Hope this helped!

Which statement is true about the equations –3x + 4y = 12 and x – y = 1?

Firlakuza [10]

-3x + 4y = 12
x - y = 1....x = y + 1

-3(y + 1) + 4y = 12
-3y - 3 + 4y = 12
-3y + 4y = 12 + 3
y = 15

x - y = 1
x - 15 = 1
x = 1 + 15
x = 16

Find the greatest four digit square number by division method

Agata [3.3K]

9999 is largest 4 digit number, and 100^2 is 10000, or 1 greater than the largest 4 digit number. This means that the closest square root of the largest perfect square is most likely 99. So 99^2 (9801)is the largest perfect square of four digits.
