Answer:

3x +6-6 =2y

=) 3x =2y

=) 3x/2 =y

Let x = 4 then, 3 ×4 / 2 =y

= ) 12/2 =y

=) 6 =y

y =6

Answer:

3

Step-by-step explanation:

3×2 + 6 - 2×3 =6

to make the LHS equals to RHS (6).

x should be 2 and y should be 3

Answer:

slope: 1.5/3

y intercept: 3

Step-by-step explanation:

the line goes through the vertical line and meets at 3

from one point to the other it goes up 3 and over 1 and a half

if 1.5/3 doesn't work try 3/1.5

The length of ND = 3 units

The length of N'D' = 6

6 / 3 = 2

The scale factor is 2

Answer:  A) 2

Step-by-step explanation:

The shape has been enlarge which means B and D are  ruled out because if a shape gets enlarge its scale factor has to be greater than 1.

We will use the coordinate of the image of D  to find the scale factor.

Pre-image:  (2,2)   Enlarge or image: (4,4)    

So as we can see to get from 2 to 4 you will have to multiply by 2. So the scale factor is  2

6*4+2 / 2-7

1: 20+2 / 2-7

2: 20+1-7

3: 21-7

14

In this equation we need to use OoO ( order of operations) Or Pemdas!

The first step seince there arnt any exponents or parenthesies we need to multiply 6*4=20 Next we need to divide 2 by 2 wich is 1. Now that we got multiplication and divition done we add 10+1 wich is 21. Last but not least wesubtract 21 by 7= 14 Therefor the awnser is 14!

Sandy didnt follow Pemdas and she did not go from left to right. She added and did not divide on step one and on step 2. All the other steps are right sandy messed up on step 1. Therfore sandy got a difrent awnser than she was soupossed to.

Answer:

19

Step-by-step explanation:

The answer is 19 because if you draw a number line and count from -3 to 16 you will get 19.

You can also add 3+16 because it takes 3 steps to go back from -3 to 0, and then 16 steps forward to go to 16.

Hope this helps!

Answer:

true for all x

Step-by-step explanation:

3(2x-4)=6(x-2)

Distribute

6x - 12 = 6x -12

Subtract 6x from each side

6x-12 -6x = 6x-12-6x

-12 =-12

Since this is always true, there are infinite solutions

Answer:

The statement is true for any value of x, because both sides are identical.

Step-by-step explanation:

Step 1- Distribute into the parenthesis

(3)2x-(3)4=(6)x-(6)2

Step 2- Simplify the equation

6x-12=6x-12

Step-by-step explanation:

Answer:

the volume of the truck = 390 ft³

Step-by-step explanation:

given:

Length that measures 10 ft, a width of 6 ft,

and a height of 6 1/2, Ft.

find:

What is the volume of the

moving truck?

volume of a rectangular prism = L x W x H

where L = length = 10 ft.

W = width = 6 ft.

H = height = 6 1/2 ft

plugin values into the formula:

V = 10 x 6 x 6.5

V = 390 ft³

therefore,

the volume of the truck = 390 ft³

Answer:

16. a = 13

Step-by-step explanation:

Answer:  see proof below

Step-by-step explanation:

Given: A + B + C = π               → A = π - (B + C)

                                               → B = π - (A + C)

                                               → C = π - (A + B)

Use Sum to Product Identity: sin A - sin B = 2 cos [(A + B)/2] · sin [(A - B)/2]

Use the following Cofunction Identity: cos (π/2 - A) = sin A

3 hours is 180 minutes as there are 60 minutes in 1 hour. How many times does 30 minutes go into 180 minutes?

180/30=6

So, we have six of these 30 minute time slots that fit into 3 hours. So, we multiply our 37.5 miles by six to find the total mileage!

Answer:

Step-by-step explanation:

It is mentioned in the question that

Height of baseball expressed in feet

T = time in seconds

Also

[tex]h= -16t^2+64t+3[/tex]

Now the time is 3.5 so put this value to the above equation

h = -16(3.5)^2 + 64(3.5) + 3

= -16(2.25) + 224 + 3

= -196 + 227

= 31

Therefore the height of a baseball is 31 feet and the same is to be considered

It is clear from the diagram that,

⇒ (2x - 5) + (x + 5) = 180

⇒ (2x + x) + (5 - 5) = 180

⇒ 3x + 0 = 180

⇒ x = 180/3

⇒ x = 60°

◈ From the geometry of figure,

⇒ ㄥ6 = (2x - 5)

⇒ ㄥ6 = (2×60 - 5)

⇒ ㄥ6 = 120 - 5

⇒ ㄥ6 = 115°

Step-by-step explanation:

Karina's statement is accurate, as the minimum requirement for a trapezoid is one pair of parallel sides.

A trapezoid is a polygon with four sides. If one side of a quadrilateral is parallel to the other it is a Trapezoid.

The statement written by Nico is

A 4-sided polygon with at least one pair of parallel sides must be a parallelogram.

The statement written by Karina is

A 4-sided polygon with at least one pair of parallel sides must be a trapezoid.

Nico's statement is incorrect because a polygon with a minimum of 2 pairs of parallel sides is a Parallelogram.

Karina's statement is correct, as a minimum of one pair of parallel sides is needed to make a trapezoid, more than one pair is a parallelogram but that is also a trapezoid with two pairs of parallel sides.

Therefore, Karina's statement is accurate.

Answer:

5m•5m•5m

Step-by-step explanation:

You are multiply the factor by itself as many times as the exponent says. so if the factor is 5m, you would multiply it by itself by the exponent, which in our case is 3.

An expression is defined as a set of numbers, variables, and mathematical operations. The expression (5m)³ can be expressed as 5·5·5·m·m·m.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The given expression (5m)³ can be expressed in the following manner,

[tex](5m)^3 = 5 \cdot 5 \cdot 5\cdot m\cdot m\cdot m[/tex]

Hence, the expression (5m)³ can be expressed as 5·5·5·m·m·m.
