Answer:
-4x^2 -3x - 5
Step-by-step explanation:
-4x^2 + 2x - 5(1 + x)
Distribute
-4x^2 + 2x - 5 -5x
Combine like terms
-4x^2 -3x - 5
Step-by-step explanation:
The problem bothers on fractions, here we are being presented with mixed fractions.
what we are going to do bascially is to subtract the sum of all the uloaded
peat moss in sites 1 and 2 to get from the peat moss to get the remaining for the third site
therefore
we then have to convert the mixed fraction to further simplify the problem we have
we then solve the fraction to the right of the negative symbol first
We can now convert to mixed fraction
For the third site the remainder is 5 12/25
Answer:
c + 3d = 14.75
2c + 5d = 26
A box of candy is $4.25 and a drink is $3.50
Step-by-step explanation:
Let c represent the cost of a box of candy and let d represent the cost of a drink
c + 3d = 14.75
2c + 5d = 26
Solve by elimination by multiplying the top equation by -2
-2c - 6d = -29.5
2c + 5d = 26
Add them together
-d = -3.5
d = 3.5
Plug in 3.5 as d into one of the equations to solve for c
c + 3d = 14.75
c + 3(3.5) = 14.75
c + 10.5 = 14.75
c = 4.25
So, a box of candy is $4.25 and a drink is $3.50
To find the volume of the box you have to do the formula for volume
the formula for volume is lxwxh aka length x width x height
so first you have to do 3/4 x 1/2
3/4 x 1/2 = 3/8
Next, you have to do 3/8 x 1/4
3/8 x 1/4 = 3/32
so the volume of the box is 3/32
HOPE THIS HELPS!!!
<span>(7 x 10^−12)(4 x 10^5)
= (7x4) x 10^-7
= 28 x 10^-7
= 2.8 x 10^-6</span>
