Step-by-step explanation:

4 1/4-5/6

Get a common denominator of 12

4 1/4 *3/3 - 5/6 *2/2

4 3/12 - 10/12

Borrow from the 4

3 + 12/12 + 3/12 - 10 /12

3 15/12 - 10/12

Answer:

2t + n + 3d = 65

3t + 2n + 5d = 85

t + n + td = 40

Step-by-step explanation:

tubs of popcorn = t

plates of nachos = n

drinks = d

The Smiths: 2t + n + 3d = 65

The Langes: 3t + 2n + 5d = 85

The Radfords: t + n + td = 40

So, the correct answer would be the one including all 3 of these equations. :)

Answer:

$f(x) = -x{}^{2}+3x-1\\=-(- 2)^{2} + 3(- 2) -1\\=4+(-6) - 1\\= -2-1\\=3$

$f(x) = - x {}^{2} + 3x - 1\\= -(2){}^{2} + 3(2) -1\\ =- 4 + 6 - 1\\ = - 2 - 1\\= 1$

A fertilizer has the analysis of 12-24-20. How many pounds of N, P, and K are there in the 3000 lbs. of fertilizer?

grigory [225]

Answer:

$W_N=642.857ibs$

$W_P=1285.714ibs$

$W_K=1071.43ibs$

Step-by-step explanation:

From the question we are told that:

Ratio of NPK $R=12-24-20.$

Weight $W=3000 lbs$

Generally the sum of the ratio is given as

$\sum R=12+24+20$

$\sum R=56$

Generally the Weight of N is mathematically given by

$W_N=\frac{12}{56}*3000$

$W_N=642.857ibs$

Generally the Weight of P is mathematically given by

$W_P=\frac{24}{56}*3000$

$W_P=1285.714ibs$

Generally the Weight of K is mathematically given by

$W_K=\frac{20}{56}*3000$

$W_K=1071.43ibs$
