Answer:

The value of x in terms of b is: [tex]\mathbf{x=-\frac{6}{2b}}[/tex]

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: [tex]-2(bx-5)=16[/tex]

First we need to find

The value of x in terms of b

We need to find value of x

[tex]-2(bx-5)=16[/tex]

Multiply -2 with terms inside the bracket

[tex]-2bx+10=16[/tex]

Subtract 10 from both sides

[tex]-2bx+10-10=16-10\\-2bx=6[/tex]

Divide both sides by -2b

[tex]\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}[/tex]

So, The value of x in terms of b is: [tex]\mathbf{x=-\frac{6}{2b}}[/tex]

The value of x when b is 3

We have the equation for the value of x in terms of b:

[tex]\mathbf{x=-\frac{6}{2b}}[/tex]

Put b = 3

[tex]x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1[/tex]

So, The value of x when b is 3 is: x = -1

(HELP) My Subaru Crosstrek can travel 107 miles on 3 gallons of gas. How many miles can my
car travel on a full tank of gas? A full tank of gas is 14 gallons.

Answers

9514 1404 393

Answer:

  499 1/3 miles

Step-by-step explanation:

Let m represent the number of miles the car can travel on 14 gallons. We assume distance is proportional to gas usage, so ...

  m/14 = 107/3

Multiplying by 14, we have ...

  m = 14(107/3) = 1498/3 = 499 1/3

The car can travel 499 1/3 miles on a full tank of gas.

The number of fish in a lake decreased by 25% between last year and this year.
Last year there were 60 fish in the lake. What is the population this year?

Answers

the population would be 45 fish

Answer: This population, the population is 45 fish.

Step-by-step explanation: This problem can be solved by a rule of three.

Last year there were 60 fish in the lake. That was 100, that is, decimal 1.

This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So

60 fish - 1

x fish - 0.75

This population, the population is 45 fish.

To complete a planter box, mr. Michaels will purchase cedar boards that are 2 inches wide and 8 inches long. He will need to cut down the length of the boards into pieces that are 1 1/3 inches long. How many pieces can mr. Michael cit from each 8 inch board so he can determine how many he will need to purchase?

Answers

Answer:

6 pieces

Step-by-step explanation:

Since Mr. Michaels need to cut down the 8 inch long boards into pieces that are 1¹/₃ inches long, the number of pieces he can cut out from the 8 inch long board that are 1¹/₃ inches long is 8 ÷ 1¹/₃ = 8 ÷ 4/3

= 8 × 3/4

= 2 × 3

= 6

So, Mr. Michaels can cut 6 pieces that are 1¹/₃ inches long from the 2 inches wide and 8 inches long board.

the perimeter means you add up all the sides
so you do

(12b-8) + (12b-8) + (9b+8)
now you just add the like terms

12b+12b+9b = 33b
-8+-8+8= -8
so the perimeter is 33b-8

A map has a scale of 1 cm to 14 km.
On the map, the distance between Manchester and London is 18.8 cm.

What is the real distance, in km, between Manchester and London?

Answers

Answer:

Real distance between Manchester and London = 263.2 km

Step-by-step explanation:

Given that:

A map has a scale of 1 cm = 14 km

Ratio = 1 : 14

Distance from Manchester to London = 18.8 cm

Let,

x be the real distance between Manchester and London.

Ratio = 18.8 : x

As the relationship is proportional,

1 : 14 :: 18.8 : x

Product of mean = Product of extreme

14*18.8 = x

x = 263.2 kilometers

Hence,

Real distance between Manchester and London = 263.2 km

A video store is offering 20% off all outdated videos. Let s be the original price of the purchase. Use the expression s-0.2s for the new price of the purchase. Write an equivalent expression by combining like terms.

Answers

Answer: The equivalent expression is:

new price = s*0.8

Step-by-step explanation:

When the original price of something is A, and we have X% off, the new price if that object will be:

New price = A - (X%/100%)*A

Like in this case, the original price is s, and the discount is 20%

Then the new price can be written as:

new price = s - (20%/100%)*s = s - 0.2*s = s*(1 - 0.2) = s*0.8

This is the equivalent expression we wanted to get.

 

Answer:

new price = s*0.8
