If 50 liters cost $325, how many liters would cost $130?

Answers

Answer 1

Answer:

20 liters

Step-by-step explanation:

$325 / 50L = $6.5 per L

$130 = ? L

To find this, divide 6.5 from 130

130 / 6.5 = 20L

Answer 2

Answer:

20 liters

Step-by-step explanation:

50 liters cost $325 and the price should stay linear.

So we can solve like this...

325/50 = 6.50

One liter costs $6.50

130/6.50 = 20

20 liters would cost $130.

B. 25°

C. 108°

D. 130°

Answers

Answer:

90 degrees

Step-by-step explanation:

A triangle's degrees add up to 180. You are already given 2 of the. Let x be the 3rd angle. Here is the equation: 29+61+x=18. x=90.

Hope this helped!

Answer:

A.90°

Step-by-step explanation:

A triangle's interior angles are equal to 180°.

So since two angles are given all you need to do is add the given angles and subtract the sum from 180°.

61°+29°=90°

180°-90°=90°

The missing angle m<R is equal to 90°

Your answer is: A.90°

Hope this helps! :)

Log10 (2x + 1) - logio(3x - 2) = 1

Answers

Answer: x=3/4

Step-by-step explanation:

To solve, first express the left side as one logarithm. To do so, apply the quotient rule which is log_bM/N=log_bM-log_bN .

log((2x+1)/(3x-2))=1

Then, express the equation to its equivalent exponential form to eliminate the logarithm.

Note that the exponential form of log_b M=a is M=b^a .

Since the base of the logarithm in the given equation is not written, it indicates that its base is 10.

So re-writing the equation, it becomes:

log_10((2x+1)/(3x-2))=1

And its exponential form is:

(2x+1)/(3x-2)=10^1

(2x+1)/(3x-2)=10

Now that the equation has no more logarithm, the next step is to remove the x in the denominator.

To do so, multiply both sides by 3x-2.

(3x-2)*(2x+1)/(3x-2)=10*(3x-2)

2x+1=30x-20

Next, combine like terms.

To combine 30x and 2x, bring them together on one side of the equation. So, move 2x to the right side by subtracting both sides by 2x.

2x-2x+1=30x-2x-20

1=28x-20

To combine 20 and 1, bring them together on the side opposite the term with x. So, add both sides by 20.

1+20=28x-20+20

21=28x

And, divide both sides by 28 to have x only at the right side.

21/28=(28x)/28

3/4=x

Hence, the solution to the given equation is x=3/4 .

For this question, find the common denominators of the fraction to add them.

A common multiple of 6 and 8 is 24.

So, 5*4 = 20 6*4 = 24

3 20/24 of potting soil initially

Then, 3*3 = 9 8*3 = 24

2 9/24 used

To find how many pounds are left:
