Answer:

The answer is w - 2 = 4.

Step-by-step explanation:

w + 7= 11 is not correct because 4 + 7= 11 and the solution is true.

w - 1= 3 is not correct because 4 - 1= 3 and the solution is true.

6 + w = 10 is not correct because 6 + 4 = 10 and the solution is true.

w - 2 = 4 is correct because 4 - 2 does not = 4, but 2 and the solution is not true.

Therefore, w - 2 = 4 is correct.

I hope this Helps! Have a great day (:

The number of bacteria, B, in a refrigerated food is given by the function b(t) = 15t2 - 60t + 125, where t is the temperature o

Nimfa-mama [501]

Answer: $b(t(h))=135h^2+180h+125$

Step-by-step explanation:

Given: The number of bacteria, B, in a refrigerated food is given by the function $b(t)=15t^2-60t+125$ , where t is the temperature of food in degrees Fahrenheit.

The function $t(h)=3h+4$ gives the temperature, t, of the food h hours after being removed from the refrigerator.

Now, the number bacteria in the food in h hours is given by:-

$b(t(h))=15(3h+4)^2-60(3h+4)+125\\=15(9h^2+16+24h)-180h-240+125\\=135h^2+240+360h-180h-240+125\\=135h^2+180h+125$

So, The number bacteria in the food in h hours is given by:

$b(t(h))=135h^2+180h+125$

The sum of two numbers is 73. When the smaller number is subtracted from twice the greater number, the result is 50. Find the nu

Karolina [17]

Answer:

The big number is 41 and the small number is 32.

Step-by-step explanation:

b + s = 73

2b - s = 50 Add these equations together

3b = 123 Divide both sides by 3

b = 41

Now plug this into the first equation to find s

41 + s = 73

-41 - 41

s = 32
