Answer:

Step-by-step explanation:

0.25(x+40) = 3+0.75(x - 4)

Answer:

Step-by-step explanation:

Let the consecutive even integers be 2n and 2n+2.

lesser integer = 2n

Greater integer = 2n+2

If twice the lesser of two integers is 4 less than two times the greater integer, this is expressed mathematically as;

2(less integer) = 2(greater integer) - 4

Substituting the given integers;

2(2n) = 2(2n+2)-4

2(2n) = 2[(2n+2)-2]

2n = 2n+2-2

2n = 2n

2 = 2

This two values cancels out and become 0 = 0. This equality shows that it is an identity pair and it is true for all even integers.

Yes, the shape I can onto shape II by a sequence of transformations.

Two images are given we have to determine that whether any of shape can onto other shapes.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The shape I can be mapped into shape II through a series of transformations.

The first sequence would involve translating shape I 8 units up and 4 units left, reflecting shape I across the x-axis, then rotating shape I 90 degrees counterclockwise about the origin.

Therefore, the shape I can onto shape II by a sequence of transformations.

9/5 + 9/5 = 18/5 = 3 3/5

15 x 6 = 90

90 + 3 3/5 = 93 3/5

Step-by-step explanation:

65 - 32 = 13

13 divide by 65 = 0.20

0.20 x 100% = 20%

so the percentage drop is 20%

therefore, Marcus is correct.

Answer:

-13/4

Step-by-step explanation:

1.) convert to improper fraction.

-39/8 * 2/3

2.) multiply top

-39 * 3 = -117

3.) multiply bottom

8 * 3 = 24

4.) simplify

-117/24 = -13/4

Answer: y= - 4x+18

Step-by-step explanation:

Equation: y=mx+b

***remember: b is the y-intercept and m is the slope.

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

3= x1

2= x2

6= y1

10=y2

m=[tex]\frac{10-6}{2-3}[/tex]= [tex]\frac{4}{1}[/tex]= -4

m=-4

Now we have y=-4x+b , so let's find b.

You can use either (x,y) such as (3,6) or (2,10) point you want..the answer will be the same:

   (3,6). y=mx+b or 6=-4 × 3+b, or solving for b: b=6-(-4)(3). b=18.

   (2,10). y=mx+b or 10=-4 × 2+b, or solving for b: b=10-(-4)(2). b=18.

Equation of the line: y=-4x+18

Answer:

x=2c/3+1

Step-by-step explanation:

Subtract 2c from both sides.

−3x=−3−2c

The equation is in standard form.

−3x=−2c−3

Divide both sides by −3.

-3x/-3=-2c-3/-3

Dividing by −3 undoes the multiplication by −3.

x=-2c-3/-3

Divide −3−2c by −3.

x=2c/3+1

Answer: Choose which answer you think fits

Step-by-step explanation:

The roots are there to confuse you. They have the exact same numbers under the radical, so you can treat it like a variable and add 4 + 3 since theyre like terms.

[tex]7(5\sqrt{x2y} ) = 35\sqrt{x2y}[/tex]

If that's an x^2, bring the x out and keep the y inside the radical to get:

[tex]35x\sqrt{y}[/tex]

Answer:

I notice that the first equation has a 7x, term and the second equation has a -7x term. These terms will cancel if we add the equations together—that is, we'll eliminate the the x terms:

Step-by-step explanation:

2y+7x= -5 + 5y-7x=12

0.07 = 0.07

0.07 > 0.06 (or any number greater than 0.07)

0.07 < 0.08 (or any number less than 0.07)

Answer:

1) 0.07 can only equal 0.07

2) > means greater than, so the answer would be anything greater than 0.07.

3) < means less than, so the answer would be anything less than 0.07.

What is Congruency

Triangles that are identical in size and shape are said to be congruent triangles. Inferred from this is that the matching sides and angles are equal. Without checking each of the triangles' sides and angles, we can determine whether the two triangles are congruent.

Rule of Congruency:

1- SAS (Side-Angle-Side): Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle.

2- ASA (Angle-Side-Angle): Two triangles are congruent if two triangles and the included side of one triangle are equal to two angles and the included side of the other triangle.

3- AAS (Angle-Angle-Side): Two triangles are congruent if any two pairs of angles and one pair of corresponding sides are equal.

4- SSS (Side-Side-Side): If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.

5- RHS (Right angle- Hypotenuse-Side): If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent.

Since JK= QP
KL= KR
Angle LKJ= Angle QRP

So Δ LKJ ≅ Δ QRP.

Answer:

let's see what to do...

Step-by-step explanation:

H is between G and I.

G I = G H + H I

38 = 8 x + 7 + 3x - 2

38 = 11 x + 5

subtract the sides of equation minus 5

38 - 5 = 11 x + 5 - 5

33 = 11 x

divided the sides of equation by 11

33 ÷ 11 = 11 x ÷ 11

3 = x

So the lenght of (G H) is :

8 x + 7 -----¢ 8 (3) + 7 = 24 + 7 = 31

And we're done.

Answer:

30

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| - 10 | + | - 20 |

= 10 + 20

= 30

Answer:

|-10| + |-20| = 30

Step-by-step explanation:

Absolute Value

The absolute value of x, written |x| is a positive number that represents the distance from the origin and the number.

In practice, the absolute value is found writing the number without the negative sign, if present.

For example:

|-9| = 9

|76| = 76

|0| = 0

The given expression is

|-10| + |-20|

Calculate each absolute value separately:

|-10|=10

|-20|=20

Thus:

|-10| + |-20| = 10+20 = 30

|-10| + |-20| = 30
