2 * 2 and 3/4.

2 and 3/4 = (4*2 + 3) / 4 = (8 + 3) / 4 = 11 / 4

2 * 11/4 = 22 / 4 = 5 and 2/4

= 5 and 2/4 or 5 and 1/2 or 5.5

Hope this helps.

F−g+(−2)f, minus, g, plus, left parenthesis, minus, 2, right parenthesis where f = -3.005f=−3.005f, equals, minus, 3, point, 005

valentina_108 [34]

Answer:

$f-g+(-2) = -9.705$

Step-by-step explanation:

Given

$f = -3.005$

$g=4.7$

Required

Determine $f-g+(-2)$

We have:

$f-g+(-2)$

Open brackets

$f-g+(-2) = f-g-2$

Substitute values for f and g

$f-g+(-2) = -3.005-4.7-2$

Solve

$f-g+(-2) = -9.705$

4. A solution of 60% fertilizer is to be mixed with a solution of 21% fertilizer to form 234 liters of a 43% solution. How many

solniwko [45]

Given:

A solution of 60% fertilizer is to be mixed with a solution of 21% fertilizer to form 234 liters of a 43% solution.

To find:

The quantity of the 60% solution in the mixture.

Solution:

Let x be the quantity of the 60% solution and y be the quantity of the 21% solution.

Quantity of mixture is 234. So,

$x+y=234$

$x=234-y$ ...(i)

The mixture has 43% fertilizer. So,

$\dfrac{60}{100}x+\dfrac{21}{100}y=\dfrac{43}{100}\times 234$

Multiply both sides by 100.

$60x+21y=10062$ ...(ii)

Using (i) and (ii), we get

$60(234-y)+21y=10062$

$14040-60y+21y=10062$

$-39y=10062-14040$

$-39y=-3978$

Divide both sides by -39.

$\dfrac{-39y}{-39}=\dfrac{-3978}{-39}$

$y=102$

Putting this value in (i), we get

$x=234-102$

$x=132$

Therefore, 132 liters of the 60% solution must be used.
