7n - 4 (8n+4) = 159
Romashka [77]

Answer:

n = -7

Step-by-step explanation:

Use distributive property:

7n - 32n - 16 = 159

Combine like terms

-25n - 16 = 159

Add 16 to both sides to isolate variable n

-25n = 175

Divide both sides by -25 to isolate variable n

n = -7

Check your work:

7(-7) - 32(-7) - 16 = 159

-49 + 224 - 16 = 159

159 = 159

I'm not very good at solving these problems
notka56 [123]

1 atom of C has a mass of 12 amu (atomic mass unit).

1 atom of O has a mass of 16 amu.

1 molecule of CO₂ thus has a mass of 12 + 2×16 = 44 amu.

C thus makes up 12/44 ≈ 0.27 of the total mass of CO₂, while O makes up the remaining 32/44 ≈ 0.73.

Then in a 2 kg = 2000 g block of CO₂, carbon makes up about 12/44 × 2000 ≈ 545 g.

In a recent year, 19.4% of all registered doctors were female. If there were 52,500 female registered doctors that year, what wa
sukhopar [10]

Answer: 10,185 registered female doctors.

Step-by-step explanation: We basically want to find how many females were doctors, if 19.4% of the 52,500 females were registered doctors. Basically we want to find 19.4% of 52,500. We will write an equation that works to solve this problem.

19.4/100 = x/52,500 (This equation represents that 19.4% out of 100% is x out of the 52,500 registered doctors.) Solve for x.

19.4/100 x 52,500 = x/52,500 x 52,500.

(19.4 x 52,500 = 1,018,500/100 = 10,185. And, x/52,500 x 52,500 = x.

10,185 = x.

So, 19.4% of all registered doctors would be 10,185 females out of 52,500 females.
