Answer:

Adrian would have to purchase 9 cans and 3 frozen dinners.

step-by-step explanation:

Let us consider the sodium is denoted by a variable "s"

Let us consider the can is denoted by a variable "c"

Each can of soup containing the sodium = s = 350 mg  

Each frozen dinner containing the sodium = s = 700 mg  

The number of cans purchased by Adrian = c = 9 cans

The total amount of sodium = 5250 mg

Total amount of sodium purchased by Adrian

in 9 cans = 9 × 35  = 3150 mg

Subtracting 5250 mg by 3150 mg will give 2100 mg

So,   5250 mg - 3150 mg = 2100 mg

Dividing 2100 mg by 700 mg of sodium of frozen sodium will give the value 3.

So, Adrian would have to purchase 3 frozen dinner.

<u>Hence, Adrian would have to purchase 9 cans and 3 frozen dinners to collectively contain 5250 mg of sodium.</u><u> </u>

Verification:  

The total amount of sodium = 5250 mg

Total amount of sodium purchased by Adrian in 9

cans = 9 × 350 = 3150 mg

Total amount of sodium purchased by Adrian in 3 frozen dinners = 3 × 700 = 2100 mg

Total sodium = sodium purchased in cans + sodium purchased in frozen dinners

5250 = 3150 + 2100

5250 = 5250

L.HS = R.HS

Question
Aleonysh [2.5K]

Answer:

\large \boxed{-40, \ 4, \ -4}

Step-by-step explanation:

f(x)=-9x+14

\sf Put \ x \ as \ 6.

f(6)=-9(6)+14

f(6)=-54+14

f(6)=-40

g(x)=-3x^2

\sf Put \ g(x) \ as \ -48.

-48=-3x^2

\displaystyle \frac{-48}{-3} =\frac{-3x^2 }{-3}

16=x^2

\sqrt{16} =\sqrt{x^2 }

x= \pm 4
