you buy 6 apples for $2.70 write and equation that can be used to express the relationship between the total price t and the number of apples a you buy.


1. t= 2.70a

2. t=0.45a

3. t=6a

t= 2.22a​

Answers

Answer:

The correct answer is: 2. t=0.45a

Step-by-step explanation:

Let t be the price of apples

and a be the number of apples

The price and quantity are directly proportional

[tex]t \propto a[/tex]

Removing the proportionality symbol introduces a proportionality constant in the equation

[tex]t = ka[/tex]

So far we know that cost of 6 apples is $2.70

Putting in the equation

[tex]2.70 = k (6)\\k = \frac{2.70}{6}\\k = 0.45[/tex]

Putting the values of k will give us:

[tex]t = 0.45a[/tex]

Hence,

The correct answer is: 2. t=0.45a

5(x – 3) = -15 + 10(x + 3) – 5x
Please help

Answers

Answer:

There are no solutions.

Step-by-step explanation:

Expand 5(x-3) 5x-15

Expand -15+15=5x+15+15

Add 15 to both sides

5x-15+15=5x+15+15

Simplify

5x=5x+30

Subtract 5x from both sides

5x-5x=5x+30-5x

0=30

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We must find the length for the segment AB. The coordinates of the endpoints are A(-3,2) B(0,6).

Calculating the distance:

[tex]d=\sqrt{(0+3)^2+(6-2)^2}[/tex]

[tex]d=\sqrt{3^2+4^2}[/tex]

[tex]d=\sqrt{9+16}[/tex]

[tex]d=\sqrt{25}[/tex]

d = 5 units

The length for segment AB is 5 units

Jadynn's washing machine holds l,086 liters of water. how much water dose it hold in gallons? A gallons is approximately 3.79 liters. round to the nearest tenth

Answers

Answer:

286.5 gallons of water

Step-by-step explanation:

1,086 ÷ 3.79= 286.5435356

Round to the nearest tenth

286.5

Answer:

286.54 gallons

Step-by-step explanation:

You have 1,086 liters and you are trying to find how many gallons it is

Luckily you are given how many liters go into a gallon

So from there it's simple division

1,086/3.79 = 286.5435356200528

Now, it tells you that you only need to round to the nearest tenth. And since the nearest tenth isn't greater than 5, you can just leave it as 286.54

So, 286.54 gallons is the amount that the washing machine holds

3^2x-1=27^x-1

Answers

Step-by-step explanation:

3^(2x) - 1 = 27^x - 1

3^(2x) = 27^x

3^(2x) = (3^3)^x

3^(2x) = 3^(3x)

Therefore 2x = 3x and x = 0.

Which of the following shapes are rhombuses ? Choose two correct answers !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!

Answers

Answer:

Hi there! Your answer is C and D

Step-by-step explanation:

You might know that a Rhombus is a special type of parallelogram whose all sides are equal. The difference between a square and a rhombus is that all angles of a square are right angles, but the angles of a rhombus need not be right angles. So, a rhombus with right angles becomes a square. B is not because all sides are equal and it has right angles. A is not because it does not have equal sides. I hope this helps! :]
