1/2 t-4(2+t)=20
1/2 t-8-4t=20
least common multiple=2
t-16-8t=40
-7t=40+16
-7t=56
t=56/-7=-8
Answer: t=-8
To check
-8/2 - 4(2-8)=-4-4(-6)=-4+24=20
No there isn’t enough water, 975 divided by 70 is 13.92 indicating there would only be enough water for 13 experiments and not 15
Answer:
x=36
Divide the corresponding side (16) by 4/7
Answer:
2x-3y=9 and 4x-6y=30
Step-by-step explanation:
hello :
note y=(2/3)x+5 no y=23x+5
2/3 is the slope....... all lines parallel to this line has same slope.
1) 2x-3y=9 means : 3y = 2x-9 divide by 3 : y=(2/3)x-3..same slope.
2) 4x-6y=30 means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6
but 4/6 = 2/3 so : y=(2/3)x-5..same slope.
