Put the equation in standard form with a positive x coefficient. 2y+5=-4(x+2)
umka21 [38]

The standard form of equation is: 4x+2y = -13

Step-by-step explanation:

the standard form of a linear equation in two variables is given by:

ax+by = c

Given equation is:

2y+5=-4(x+2)

Distributing -4 into the round bracket

2y+5 = -4x-8

Adding 4x on both sides

4x+2y+5 = -4x-8+4x\\4x+2y+5 = -8

subtracting 5 from both sides

4x+2y+5-5 = -8-5\\4x+2y = -13

The standard form of equation is: 4x+2y = -13

Pauty went to the shopping mall at 11:30 A.M.
natka813 [3]
It’s 12:35, if you add 40+25 it equals 65, 60 minutes is an hour, subtract 65-60 and you’ll get 5. The hour brings you to 12:30 and then you add the remaining time (5 minutes), which will give you 12:35.
