Darcy harvest 8 3/4 acres of corn every 5/6 of an hour. How many acres per hour?
otez555 [7]

Answer:

The answer is 10\frac{1}{2}\ per\ hour.

Step-by-step explanation:

Given:

Darcy harvest 8 3/4 acres of corn every 5/6 of an hour.

Now, to find the acres per hour it takes to harvest.

Darcy harvest = 8\frac{3}{4}=\frac{35}{4}\ acres.

The time he took to harvest = \frac{5}{6}\ hour.

So, to get the acres per hour we put formula:

Distance = \frac{35}{4}\ acres.

Time=\frac{5}{6}\ hour.

Speed=\frac{distance}{time}

Speed=\frac{\frac{35}{4}}{\frac{5}{6}}

Speed=\frac{35}{4}\times \frac{6}{5}

Speed=\frac{210}{20}

Speed=\frac{21}{2}

Speed=10\frac{1}{2}\ per\ hour.

Therefore, the answer is 10\frac{1}{2}\ per\ hour.

Solve the system of equations using the linear combination method.
Firdavs [7]
1. 5m+3n=41   
3m-6n=9 (multiplying the first equation by 3 and the second by 5), we get;

15m+9n=123
15m-30n= 45 (subtracting the two equations)         
39n = 78           
     n = 2, and
to get m we substitute n with 2
       3m = 9+6(2)                       
             3m = 21                   
                m = 7
Therefore, n=2 and m=7

2. 6g +8h=40
    -6g +2h = -20(Adding the two equations to eliminate g)
             10 h= 20
                 h =2 
to get g we substitute h with two
6g= 40- 8(2)
    = 24
    g= 4
Therefore, g =4 and h =2

3. 9x +5y =35
    2x + 5y =0 (subtracting the two equations to eliminate y)
           7x =35
             x= 5
To get y we substitute x with 5
5y=35-9(5)
  5y = -10
    y = -2
Therefore, x=5 and y=-2
