Answer:
x = 2
Step-by-step explanation:
24 - 7x = 10
Rearrange terms,
-7x + 24 = 10
Subtract 24 from both sides,
-7x + 24 - 24 = 10 - 24
-7x = 10 - 24
-7x = -14
Divide by sides by -7,


x = 2
you need 10 8' planks of wood because 15x3= 45+9x4= 77, then 77÷8= 9.625, but you can't get .625 of a plank, so 10. hope you get a good grade!

Answer:
30, 10
Step-by-step explanation:
length=x
wdith=y
xy=300, x=3y
replace x with 3y in the first equation to get
3y^2=300
y^2=100
since you cant have a negative side of a garden, y=10. x=30.
