Answer:

x=11

Step-by-step explanation:

6=x-5

11=x

Answer: The answer is 11.

Step-by-step explanation: If y=6 and the problem is y=x-5 Then you could do 5+6 (since we know y=6) and get the answer of 11. To check it the answer you can do 11-5 which equals 6.

I hope this helps

Answer:

15 sides

Step-by-step explanation:

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:

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.

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! :]

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

Answer:

If the equation is "5/7(x)=3" then the answer's x=21/5

Step-by-step explanation:

Combine multiplied terms into a single fraction.

Multiply all terms by the same value to eliminate fraction denominators.

Simplify.

Divide both sides of the equation by the same term.

Simplify.

Answer:

The length for segment AB is 5 units

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

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

Answer:

The slope of AB is 4/3

Step-by-step explanation:

The Slope of a Line

If a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

It's required to find the slope of the line AB shown in the figure. The coordinates of the endpoints are A(-3,2) B(0,6), thus the slope is:

[tex]\displaystyle m=\frac{6-2}{0+3}[/tex]

[tex]\displaystyle m=\frac{4}{3}[/tex]

The slope of AB is 4/3

Answer:

[tex]\sqrt{x} 42[/tex], [tex]\sqrt{x} 114[/tex], 12, [tex]\sqrt{x} 150[/tex],22

Step-by-step explanation:

the numbers are 22 [tex]\sqrt{x} 150\\[/tex] [tex]\sqrt{x} 114[/tex] [tex]\sqrt{x} 42[/tex] and 12, 22 and 12 stays the same

[tex]\sqrt{x} 150[/tex] gives you= 12.24

[tex]\sqrt{x} 114[/tex]=10.67

[tex]\sqrt{x} 42[/tex]=6.48
