Answer:
6x + 14 ≥ 28
Step-by-step explanation:
6 times a number (6x)
14 more than (so, add 14 to 6x)
greater than or equal to, so this symbol ≥
= 6x + 14 ≥ 28
SOLVED:
6x≥14
x≥2.333333333333333
Answer:
A. 605 mL of the 35% solution
B. 55 mL of the 95% solution
Step-by-step explanation:
It is given that, you need 660 mL of a 40% alcohol solution. On hand, you have 35% alcohol mixture. You also have a 95% alcohol mixture.
Let x and y be the amount of 35% alcohol solution and 95% alcohol solution (in mL) respectively.
So,
Amount equation:
...(1)
Alcohol equation :
...(2)
On solving (1) and (2), we get
Now, substitute y=55 in (1).
Therefore, we need 605 mL of the 35% solution and 55 mL of the 95% solution.
Answer:
1 inch = 80 miles
Step-by-step explanation:
4 and three quarters = 4.75
380 divided by 4.75 = 80
Double check and multiply 4.75x80
4.75 x 80 = 380
D/H = 0.25
18/H = 0.25/1
Cross multiply and solve for H
