How do I solve this-
A) -0.3 = -30c
B) [tex]1/5[/tex]a = -6
C) 14 - b = 14.2
Answers
A) -0.3=-30c
divide on both sides ⇒ [tex]\frac{-0.3}{-30} = \frac{-30c}{-30}[/tex]
0.01 = c
B) do the same way. a =-30
C) 14 - b = 14.2
+14 +14
-1b = 28.2
-1b/-1 = 28.2/-1
b = -28.2

The mass of an average grain of table salt in a sample is about 3 x 10^-4 , and the mass of an average grain of rock salt in a sample is about 1.2 x 10^-2
Part A: Convert both masses to standard notation.
Part B: the mass of an average grain of rock salt is about 40 times the mass of an average grain of table salt. If you multiply the mass of table salt in standard notation by 40, what value do you get?
Part C: Is the value you got in part B equal to the mass of an average grain of rock salt? what does this mean?
Answers
Answer:
a. standard notation means in the number written in only number digits.
- to convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.
remember: if the exponent is negative, you have move the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.
3 X 10^-4 --> move 4 places to the right.
answer - table salt: 0.0003
1.2 X 10^-2 --> move 2 places to the right.
answer - rock salt: 0.012
b. we know the standard notation of table salt is 0.003, so we simply multiply 40 by this.
answer - 0.0003 X 40 = 0.012
c. 0.012 = 0.012 (yes)
answer - yes the value i got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.
- i am not sure about the "what does this mean" part. you can put whatever there but i put what i think it could be. i think it would be based on what notes you took on class.
Part(a),
The value of the masses in standard form is Rock salt: 0.012 and Table salt: 0.0003.
Part(b),
The multiplication is 0.012.
Part(c),
yielded a value equal to the mass of an average grain of rock salt. This demonstrates that the mass of an average grain of rock salt is 1/40 that of an average grain of table salt.
How to calculate the standard form?a. Standard notation means in the number written in only number digits. To convert these multiply the two numbers given. FYI these are given in scientific notation, which is used so that numbers are easier to write.
If the exponent is negative, you have moved the decimal to the right. whereas, if the exponent is positive, you have to move the decimal to the left.
3 X 10⁻⁴ --> move 4 places to the right.
Table salt: 0.0003
1.2 X 10⁻² --> move 2 places to the right.
Rock salt: 0.012
b. We know the standard notation of table salt is 0.003, so we simply multiply 40 by this.
0.0003 X 40 = 0.012
C. 0.012 = 0.012 (yes)
Yes, the value I got in part B is equal to the mass of an average grain of rock salt. this shows that the mass of an average table salt is 1/40 times smaller than the mass of an average grain of rock salt.

2:3
4:6
6:9
18:27
Step-by-step explanation:
The constant of proportionality is 2:3 for this problem. On the second one, I saw that there was a 6. 6 was double what 3 is so I multiplied 2 by 2 and got 4. I basically did that with the rest of the problems. like the second one there is a 6 on the left side, 6 is 3 times the amount of two so I multiplied 3 by 3 to get 9. On the last one, there was a 27 on the right side. 27 is 9 times greater than 3 so I multiplied 2 by 9 to get 18 on the left side. I hope I didn't make it too confusing.

Jada walks up to a tank of water that can hold up to 12 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 8 gallons of water. Four minutes later, the tank contains 5 gallons of water.
A) At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
B) How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
C) How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answers
2) we have 5 gallons and lose 2/3 gallons per minute
(2/3 gal/minute)(x minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) There was 10 gallons when the tank is full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
The tank was full 4 1/2 minutes before Jada arrived
gallons per minute since it decreases by 2
gallons in 3 minutes
2) we have 5 gallons and lose 2/3 gallons
per minute
(2/3 gal/minute) (x minutes) = 5 gallons
X=5(3/2) = 15/2 =7.5 minutes to drain the
other 5 gallons
3) There was 10 gallons when the tank is
full
That is 3 gallons more than the 7 gals
there when Jada arrived.
(2/3)(x) = 3
x=3(3/2) = 9/2 = 4 1/2 minutes

There were 1150 pounds of flour in the grain store. After most of the flour was sold, there were 230 pounds left. What was the percentage decrease of the grain store’s flour?
Answers
9514 1404 393
Answer:
80% decrease
Step-by-step explanation:
The percentage change is found from ...
percent change = ((new value)/(old value) -1) × 100%
= (230/1150 -1) × 100%
= -0.8 × 100%
= -80% . . . . . a negative change is a decrease
The store's flour quantity decreased by 80%.

Step-by-step explanation:
{4x−2y=102x−y=5
{y=2x−3−2x+y=−5
{2x−5y=143x+4y=10
The system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
A) The given system of equations are 4x−2y=10 and 2x−y=5
4/2 = (-2)/(-1)=10/5
2=2=2
Since, a₁/a₂ =b₁/b₂=c₁/c₂
The system of equations have infinitely many solution, so they are consistent dependent.
B) y=2x-3 and -2x+y=-5
Here, 2x-y-3=0 and -2x+y+5=0
2/(-2)=(-1)/1≠(-3)/5
-1=-1≠(-3)/5
Since, a₁/a₂ =b₁/b₂≠c₁/c₂
The system of equations are parallel, so they are inconsistent equations.
C) 2x−5y=14 and 3x+4y=10
Here, 2x-5y-14=0 and 3x+4y-10=0
2/3≠(-5)/4≠(-14)/(-10)
Since, a₁/a₂ ≠b₁/b₂
The system of equations have unique solution, so they are consistent independent.
Therefore, the system of equations 2x−5y=14 and 3x+4y=10 have unique solution, so they are consistent independent.
