Answer:
if red = 1 white = 4/3 or 1 1/3
if white = 1 red = 3/4
if red = 4 white = = 16/3 = 5 1/3
if white = 5 red = 15/4 = 3 3/4
Step-by-step explanation:
white 4
--------= ---------
red 3
if red = 1
white 4
--------= ---------
1 3
using cross products
white *3 = 4*1
divide by 3
white = 4/3
if white = 1
1 4
--------= ---------
red 3
using cross products
3*1 = 4* red
divide by 4
3/4 = red
if red = 4
white 4
--------= ---------
4 3
using cross products
white *3 = 4*4
white *3 = 16
divide by 3
white = 16/3 = 5 1/3
if white = 5
5 4
--------= ---------
red 3
using cross products
3*5 = 4* red
15 = 4 * red
divide by 4
15/4 = red
3 3/4 = red

B) −5x − 7 > −22 and −5x − 7 ≥ −3
C) −5x > −22 and −7 ≥ −3
D) −5x − 7 < −22 and −5x − 7 ≤ −3
The equivalent form of the compound inequality −22 > −5x − 7 ≥ −3 are A) −5x − 7 < −22 and −5x − 7 ≥ −3
If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Then a Set of such values is called solution set to the considered equation or inequality.
The equivalent form of the given inequality can be obtained by dividing the inequality into two parts.
In this case, we are given -22 > -5x - 7 > -3.
The two parts are; -22 > -5x - 7 and -5x - 7 > -3.
Since the −5x − 7 and −22 have interchanged sides, the inequality sign also changes direction.
For part two, we have −5x − 7 ≥ −3 remains unchanged.
Therefore, The choice that reflects these parts is A)-5x - 7 < -22 and -5x - 7 -3
Hence, The equivalent form of the compound inequality −22 > −5x − 7 ≥ −3 are A) −5x − 7 < −22 and −5x − 7 ≥ −3

Step-by-step explanation:
57/10 cannot be simplified
but the decimal answer is 5.7
Let x be the number of needed years.
1. He deposits $10,000 into his checking account and he will withdraw $1,200 from his checking account each year. Then after x years he will have $10,000-$1,200x in his checking account.
2. He deposits $2,000 into his savings account and his savings account earns 8% interest each year, then after x years he will have
3. Equate these amounts of money:
4. Solve this equation:
Conclusion: he needs nearly 6.663 years.
