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

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%.

Lakeesha deposits $1500 into a Young Savers account. The account receives 4% interest compounded annually. What is the balance in Lakeesha's account after 2 years? After 3 years?

Answers

Answer:

1,622 after 2 years at 4% interest. $1,687 after 3.

Step-by-step explanation:

My explanation has been provided in the image linked.

In fact I think the person above me is wrong, here is why:

4 percent (interest) of 1500 = 60

Therefore,

1 year= 1560

2 years = 1620

3 years = 1680

Answers

The first one is 10ab + 20
First answer because 10(ab) is 10 ab and 10(2) is 20. Also 10 is the greatest common factor between 10ab and 20.

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

1) Gallons per minute change is -2/3 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

The tank was full 4 1/2 minutes before Jada arrived
1) Gallons per minute change is -2/3
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
The tank was full 4 1/2 minutes before

Please explain how you solved 5x+2=47

Answers

Answer:

Step-by-step explanation:

5x+2-2=47-2 subtract 2 from both sides

5x=45 simplify

5x/5  = 45/5 divide both sides by 5

x=9 simplify

Subtract 2 from both sides, then divide both sides by 5 to get X=9

An office supply store sells pencils individually or by the case. Pencils purchased individually cost $0.97 each. One case of forty pencils costs $37.20. You have an annual budget of $95.00 for pencils.

Without exceeding the annual budget of $95.00, you can purchase _____ individual pencils.

Answers

0.97, add 7 to the five
You can purchase 97 individual pencils because 0.97*97=94.09 and if you do 98 it goes over the mark so 97 is the answer.

{4x−2y=102x−y=5

{y=2x−3−2x+y=−5

{2x−5y=143x+4y=10

Answers:
Consistent Indpendent
Consistent Dependent
Inconsistent

Answers

Answer:

 (dependent)

(Incosistent)

(Independentt)

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.
