Set up a proportion!
40 minutes / 5 holes = m minutes / 20 holes
Cross multiply.
800 = 5m
m = 160.
It will take him 160 minutes to dig 20 post holes.
Good luck Fabian!
Hope this helps
Y=2x+1 is the correct answer
Answer:
ok i cant tell if the dot is a decimal or a spot, im thinking its just a spot
so the answer would be 8:2 4:1 2:0.5
Step-by-step explanation:
if it is a decimal
the first box would be 8:0.2
2x-3y= -4 because 2x=8 since x=4 so,
8 - 3y = 20
-8. -8
-3y = 12
————
-3
y = -4
Answer:
x is 6
<h3>step by step explanation</h3>
8^2x-2 = 8^4x-14
Equating the powers of 8
2x -2 = 4x -14
2x-4x = -14+2
-2x = -12
Dividing through by -2
x = 6
