K=am+3mx
K=m(a+3x)
m=K/(a+3x)
Answer: m=K/(a+3x)
Answer:
80
Step-by-step explanation:
A triangle always measures to be 180 degrees. 50+50=100 so 80 degrees is left
The area is 3.2
The scale factor is 2/5
We know that the length is 4 so 4x2/5=8/5
8/5x2=16/5. 16/5=3.2
Answer:
The total money invested in the field will be 
Step-by-step explanation:
step 1
Find the dimensions of the field
Let
x -----> the length of the field
y -----> the width of the field
we know that
The perimeter of the field is equal to



so
----> equation A
------> equation B
substitute equation B in equation A and solve for y




Find the value of x

therefore
The length of the field is 130 meters and the width of the field is 35 meters
step 2
Find the area of the field
The area of the field is

substitute

step 3
Find the number of bags of seed
Divide the area by 460

Round up to the nearest whole number

step 4
Find the cost of the seed

step 5
Find the total money invested in the field

Count the boxes and add the sides and the bottom and that’s the perimeter
