two
infinitely many

Answers

Answer 1

Answer:

its b lol

Step-by-step explanation:

jus got it right

Answer 2

There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

What is a linear equation?

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We have a linear equation in one-variable:

0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)

0.75(x + 40) = 0.7(x + 20)

75(x + 40) = 70(x + 20)

75x = 70x - 1600

x = -370

Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

the total cost of renting a cotton candy machine for 4 hours is $72. what equation can be used to model the total cost y for renting the cotton candy machine x hours

Answers

An equation which can be used to model the total cost (y) for renting the cotton candy machine (x) hours is y = 18x.

What is an equation?

An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

What is a system of equations?

A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneously.

In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Let x represent the number of hours.Let y represent the total cost.

Translating the word problem into an equation, we have;

y = 72/4 × x

y = 18x

Jason has $90 to spend. He wants to purchase a bag for $35,one eraser for $10, and three pencils. Each of the pencils costs the same price. This will use up all of Jason's money. Determine the price of a pencil.​

Answers

Answer:

1 pencil = $15

Step-by-step explanation:

Starting money = 90

Bag price = 35

Eraser price = 10

Price per 1 pencil = X

90 - 35 = 55

$55 after buying the bag.

55 - 10 = 45

$45 after buying the eraser.

45 ÷ 3 = 15

One yardstick for measuring how steadily—if slowly—athletic performance has improved is the mile run. In 1958​, the local record for the running of a certain distance was 3​ minutes, 59.3 ​seconds, or 239.3 seconds. In the​ half-century since​ then, the record has decreased by 0.5 seconds per year.

Answers

Answer:

They will hit 180 seconds in 118.6 year

Step-by-step explanation:

Let M be the record for the mile (in seconds)

Let x be the year after 1958

So, x=(year)-19548

We are given that In the​ half-century since​ then, the record has decreased by 0.5 seconds per year

So, slope = m = 0.5

Now we will use point slope form

y = mx+c

So, we can express M as,

[tex]M=239.3-0.5 \times x[/tex]

Now we are supposed to find when they will hit 180 seconds

Substitute M = 180 in equation

180=239.3-0.5x

x=118.6

So, they will hit 180 seconds in 118.6 year

      = 7/5 y

y - 0.32 y (just add)

     = 1y - 0.32y

     = 0.68 y

y - 2/5y

      = y (1 - 2/5)

      = 3/5 y
