Answer:
The total number of feet in all the boards is 90 and 5/6 feet
Step-by-step explanation:
First, it is necessary to transform the mixed number into a fraction. This can be made following the next rule:
So, the number 8 and three fourth feet is equal to:
That means that we two boards that are 35/3 feet. So, multiplying 2 by 35/3 we get the total feets for the first type of board. That is:
At the same way, we can calculate the total number of feet for the second and third type of board as:
- Four boards that are 13 and five eighths feet:
- Two boards that are 6 one half feet:
Finally, to find the total number of feet in all the boards, we need to sum the total number of feet for every type as:
Converting this number to a mixed number we get:
Because, when we divide 545 by 6, we get 90 as a quotient, 5 is the remainder and 6 is the divisor.
Answer:
use 2 defined points.
Lets use: (-3,0) and (0,3)
The equation is written as y = mx+b, where m is the slope and is the y-intercept
Slope - change in y / change in x:
Slope = (3 -0) /(0- -3) = 3/3 = 1
b is the y-intercept which is the y value when x is o, which is one of the points (0,3) so b = 3
The equation becomes y = x +3
Step-by-step explanation:
uhm you know the excrotery system to the factor
Elsa's answer is incorrect since there is a solution of the given equation. In the given logarithmic problem, we need to simplify the problem by transposing log2(3x+5) in the opposite side. The equation will now be log2x-log2(3x+5)=4. Using properties of logarithm, we further simplify the problem into a new form log (2x/6x+10)=4. Then transform the equation into base form 10^4=(2x/6x+10) and proceed in solving for x value which is equal to 1.667.
