The answer is
1.6x-(x-2.8)=(0.2x+1.5)-0.7
1.5-0.7
1.6x-(x-2.8)=0.2x+0.8
1.6x-x
0.6x+2.8=0.2x+0.8
2.8-2.8 0.8-2.8
0.6x=0.2x-2
0.6x-0.2x 0.2x-0.2x
0.4x=-2
0.4x/0.4 -2/0.4
X=-5
6 sets of birds were in a brown crate and 2 sets of birds were in a green crate? How many birds altogether were in those crates.
Answer:
- <em> 15</em>
- <em> 42,250</em>
Step-by-step explanation:
The given function is,

where,
P = the total production of apples,
x = the number of trees added.
As the quadratic function has a negative leading coefficient, so it will open downward and at the vertex the value of function is maximum.
The vertex will be at 
The value of the function will be maximum at,

Putting the values,

So at x=15 or for 15 number of trees the production will be ,maximum.
Putting x=15 in f(x) will yield the maximum production of apples.

What we know:
we know that there are <u>75</u> chicks in the hen house, we also know that in all there are 108 chicks
What we need to find:
we need to find out how many chicks were outside
Answer equation:
108 - 75 = 33
Answer:
24.6 % decrease
Step-by-step explanation:
Let x be the original temperature
Increase by 25%
x + .25x
1.25x
Decrease by 40%
The amount decreased is
(1.25x) *.40
.496x
Subtract that from 1.25x
1.25x - .496x
.754x
We need to find the percent decrease
1 - .754 = .246
24.6 % decrease
