Answer:
1-1/2. 2-15
Step-by-step explanation:
Answer:
x= 16.3
Step-by-step explanation:
3x/6+1=7
3x/7=7
times 7 on each side
3x=49
divide each side by 3
x=16.3 continuing
if the line is parallel then that means it has the same slope, jjust a different y-intercept. so you'd have to substitute both the x and y value into the equation and keep the y-intercept a variable then solve for it, you'll get 4. so the equation is y=x/3 +4
Is that the question? Because it is trying to trick you.
x=83
y=-24
Those are your answers

bd:cd=7:2
if cd is 5 cm then cd=2:5 then ab=3:x
2:5=3:x
15=2x
x=15/2
x=7.5 cm</span><span>
