Answer:

No.

Step-by-step explanation:

Plug in -2 for y and 7 for x in the first equation:

x - 5y = -3

(7) - 5(-2) = -3

Simplify. Remember to follow PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, multiply -5 with -2:

7 + (-5 * -2) = -3

7 + (10) = -3

Next, add:

7 + 10 = -3

17 ≠ -3

(7, -2) is not a solution for the given system of equations:

T + 3/4t - 7/2 how do I simplify the 3/4t fraction with t?​
Vanyuwa [196]

Answer:

1 3/4 t -7/2

Step-by-step explanation:

Answer:

from least to greatest 112 121 124 137 147 156 173 189

Step-by-step explanation:

if you subtract each number from a number that is greater than all the numbers for example 200 then what ever has the most left will be greatest and least will be least for example 121 - 200 is negative 79 and 189 - 200 is negative 11 negative 11 is higher so its a greater number there is also easier ways to do this but this is just extra
