The cost of bananas, y, is directly
proportional to x, the pounds of bananas
purchased. If 2.5 lbs of bananas costs
$1.50, find the total cost of a lbs of
bananas.

The Cost Of Bananas, Y, Is Directlyproportional To X, The Pounds Of Bananaspurchased. If 2.5 Lbs Of Bananas

Answers

Answer 1
Step 1 - divide 2.5 and 1.50

2.5/1.50 = 1.66666666667


Step 2 - multiply 1.66666666667 by 9

1.66666666667 • 9 = 15


Final answer

15
Answer 2

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

The cost of bananas, y, is directly proportional to x, the pounds of bananas purchased. Then the relationship is given as,

y ∝ x

y = kx

Then the relationship between 'x' and 'y' will be linear.  If 2.5 lbs of bananas cost $1.50. Then we have

1.50 = k (2.5)

k = 0.60  

Then the equation is given as,

y = 0.60 x

Then the total cost of 9 lbs of bananas will be given as,

y = 0.60 (9)

y = 5.4 lbs

The equation is y = 0.60x. Then the total cost of 9 lbs of bananas will be 5.4 lbs.

Laura goes to the carnival and receives 60 tokens to play games.
•each game required 4 tokens.
•At the end of the evening she used all of her tokens,how many games did laura play?
A.10
B.15
C.16
D.24​

Answers

Answer: (B) 15

Step-by-step explanation:

Laura had 60 tokens to use and each game required 4 of them. By the end of the evening all of her tokens had been spent.

Let x represent the number of games Laura has played. Since Laura used up all of her tokens we can determine that for some integer x, 60 - 4x = 0

Solve for x

60 - 4x = 0

- 4x = - 60

x = [tex]\frac{60}{4}[/tex]

x = 15

Therefore, Laura played 15 games by the end of the evening

A factory produces blue pens and black pens. Each week, 2/3 of the pens produced at the factory are black.

Write and solve an equation that can be used to determine the number of blue pens (x) produced at the factory in a week when 45,000 pens are produced.

Answers

Answer:

15,000

Step-by-step explanation:

1/3 times 45,000 = 15,00

The number of blue pens produced at the factory in a week when 45,000 pens are produced is 15,000.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given that,

A factory produces blue pens and black pens.

2/3 of the pens produced at the factory are black.

If T is the total pens produced at the factory, then the number of black pens produced is 2/3 T.

Number of blue pens = T - 2/3 T = 1/3 T

Given that,

Total pens produced = 45,000

Equation to find the number of blue pens is,

x = 1/3 × 45,000

Solving,

x = 15,000

Hence the number of blue pens produced is 15,000.

The original price of a

discount. How much
will the TV cost after
both the sale and
discount?
A) $314.15
B) $40.00
C) $326.85
D) $359.00


PLEASE HELP

Answers

Answer:

$314.15 (A)

Step-by-step explanation:

We start by subtracting the 15% discount. 15% can be represented by 0.15, and 100% can be represented by 1. So therefore, the new price of the TV will be 1-0.15 = 0.85 of the original price using just the 15% discount. Therefore, 0.85 x 399 = $339.15. We then take this number and subtract another $25 to get $314.15

I believe the answer is A) 314.15

(x-4)(x-4)
=x^2-4x-4x+16
=x^2-8x+16
it’s +16, not negative. he forgot that when you add two negatives together, it becomes positive.

Answer:

Step-by-step explanation:

first, let's solve the equation ourselves.

(x-4)^2= (x-4)(x-4)= x^2−8x+16

now, we can see what's different about the two.

we can say that Marco's answer had the number 16 as a negative, when it was supposed to be positive. Marco wrote the incorrect sign.

What is an equation of the line that passes through the point (-5,-2) and is
parallel to the line x - y = 5?

Answers

Answer:

[tex]y=x+3[/tex]

Step-by-step explanation:

What we need to know

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines have the same slope

1) Rewrite the equation x - y = 5 into slope-intercept form and identify the slope

[tex]x - y = 5[/tex]

Subtract both sides by x

[tex]x - y -x= -x+5\\-y= -x+5[/tex]

Divide both sides by -1

[tex]y= x-5[/tex]

Now, we can tell clearly that the slope (m) of this line is 1. Therefore, a line parallel to this would also have a slope of 1.

Plugging 1 as m into [tex]y=mx+b[/tex], we get:

[tex]y=x+b[/tex]

2) Find the y-intercept (b) of the line parallel to [tex]y= x-5[/tex] and find the final equation

[tex]y=x+b[/tex]

Plug in the given point (-5,-2)

[tex]-2=-5+b[/tex]

Add 5 to both sides

[tex]-2+5=-5+b+5\\3=b[/tex]

Therefore, the y-intercept of this line is 3. Now, plugging this back into our original equation, we get:

[tex]y=x+b\\y=x+3[/tex]
