2500:(325+175)= 8750-3200:8+115*2= hasil desimal dari 7/8= 6,25+(3 1/4+75%)= 4,75-1/2*(35%-1/4),=
Answer (3)
4 x − 5 y = 20 − 5 y = − 4 x + 20 y = 5 4 x − 4
B
The slope of the equation 4 x − 5 y = 20 is 5 4 . This is derived by rearranging the equation into slope-intercept form. Therefore, the answer is option B: 5 4 .
