Answer:

42 and 22 are the numbers

Step-by-step explanation:

Let the numbers be x and y

[tex]x + y = 64[/tex]

[tex]x - y = 20[/tex]

On adding both

[tex]x + y + x - y = 64 + 20[/tex]

[tex]2x = 84[/tex]

[tex]x = \dfrac{84}{2} [/tex]

[tex]x = 42[/tex]

Using 1

[tex]42 + y = 64[/tex]

[tex]y = 64 - 42[/tex]

[tex]y = 22[/tex]

Answer:

6 groups

2 girls, 3 boys

Step-by-step explanation:

To find the answer, first find the Greatest Common Factor or the GCF. The GCF in this case is 6. So, the amount of groups is 6. Then divide each number by 6, so there will be 2 girls in each group and 3 boys in each group.

Answer:

A) Translating 20 units right

Step-by-step explanation:

The triangle is in the same orientation as it would be on the other side of n. It would be translated 20 units instead of 10 because you reflected the triangle twice so you would need to multiply 10 by 2. The 10 also represents the triangle only being reflected once. It would be to the right because the triangle moved to the right.

Step-by-step explanation:

steps are in the picture above.

The length of the ladder needed to reach a window with 50 feet above the ground is 52 ft.

The angle formed with the ground and the ladder is 75 degrees.

The window is 50 ft above the ground.

The situation forms a right triangle.

Therefore, using trigonometric,

sin 75  = opposite / hypotenuse

where

Therefore,

sin 75 = 50 / h

cross multiply

h = 50 / sin 75

h = 50 / 0.96592582628

h = 51.763809036

h = 52 ft

Therefore, the length of the ladder needed to reach a window with 50 feet above the ground is 52 ft.

7 pencils in each holder

:]

Ryan will put 7 pencils in each pencil holder.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n"  ways; then the two events in succession can occur in m × n  ways.

Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.

Pencil = 21

Pencil holder = 3

Therefore, we will do as 21 divided by 3

21/3 = 7

Hence, there are 7 pencils in each pencil holder.

Answer:

3.25

Step-by-step explanation:

Perimeter of triangle = 3(5) = 15 cm

Perimeter of rectangle = 2(2x - 3 + 4)

Perimeter = 2(2x + 1)

Perimeter = 4x + 2

4x + 2 = 15

4x = 15 - 2

4x = 13

x = 13/4

x = 3.25

The difference between the numbers 1.4 and 1.7 is -0.3 after using the number line.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that:

As we can see in the number line:

1.4 < 1.7

If we take the difference between these two numbers

From the number line:

= 1.4 - 1.7

= -0.3

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

After using the arithmetic operation concept:

The difference between the numbers:

= 1.4 - 1.7

= -0.3

Thus, the difference between the numbers 1.4 and 1.7 is -0.3 after using the number line.
