Answer: 47
Step-by-step explanation:
3.50x + 5.50x + 6 = 51
# 10
9x + 6 = 51
Subtract 6 from both sides
9x = 45
Divide both sides by 9
x = 5
#11
5x - 18 - 4x = -36
x -18 = -36
Add 18 to both sides
x = - 18

y = 5/2x -11 that is the correct answer mark me as brainliest
If you would like to write 45 minutes to 1 hour in the simplest form, you can do this using the following step:
1 hour = 60 minutes
45 minutes : 60 minutes = 45 : 60 = 3 : 4 (divide both numbers by 15)
The correct result would be 3 : 4.
This is a question of direct proportionality. The mass of hemoglobin is expected to increase with increase in volume of the blood.
Therefore;
10 cm^3 of blood ---------- 1.2 g of hemoglobin
39 cm^3 of blood ---------- x g of hemoglobin
The,
x = (39*1.2)/10 = 4.68 g of hemoglobin.
That is, 39 cm^3 of blood contains 4.68 grams of hemoglobin.
