Set up a proportion of acres to days. 1/2 acre is to 4 days as 2 3/4 acres is to x days.
x= # days to clear 2 3/4 acres
2 3/4 to improper fraction= 11/4
(1/2)/4 = (11/4)/x
cross multiply
(1/2 * x) = (4 * 11/4)
on the right, the 4 "cancels out"
1/2x= 11
divide both sides by 1/2
x= 11 ÷ 1/2
to divide fractions, multiply by reciprocal/inverse of 1/2
x= 11 * 2/1
x= 22 days
ANSWER: It would take 22 days to clear 2 3/4 acres.
Hope this helps! :)
Answer:
26) x = 4
Step-by-step explanation:
26)
20x + 5 + 24x - 1 = 180
20x + 24x = 180 + 1 - 5
44x = 176
x = 176/44
x = 4
Area=l x l
32cm=2L
divide both sides by 2
L=16cm
Answer:
Explanation:
The figure labeled A cannot be because the cross and the line are not oriented in the same relative position as in X.
The figure labeled B cannot be because the line and the the image with the three lines are not oriented in the same relative position as in X.
You cannot tell about the figures labeled C because you do not see the images of the cross and the line.
The figure labeled E cannot be because the image with the three lines is not oriented in the same relative positiion with respect to the other two as in X.
You cannot tell about the figure labeled F because the image of the cross and with the three lines are not shown.
The figure labeled G is correct: you can just rotate the cube labeled X 90 degrees counterclockwise about a vertical axis that passes through the center of the cube and get the cube labeled G.
We can rewrite this by subtracting the right side to get
... 3^(-x) -x^3 -x = 0
A graphing calculator shows this to have a solution near x=0.5.
_____
There are no algebraic means for solving such a combination of exponential and polynomial functions.
