The first step for solving the equation (a - 5) - 5 = 3 is to remove the parenthesis.

a - 5 - 5 = 3

Calculate the difference between -5 and 5.

a - 10 = 3

Now move the constant to the right side of the equation and change its sign.

a = 3 + 10

Add the numbers on the right side together to get your final answer.

a = 13

Let me know if you have any further questions.

Question

Centennial park is evaluating the capacity of the park and have determined that 15 people can comfortably stand in a section that is 5ft by 8ft , the park has dimensions that are 400yds by 200 yds estimate the number of people who can fit in the park

Solution 1

We have been given that 15 people can comfortably stand in a section that is 5ft by 8ft .

Hence, the area of this section is given by

Hence, we can say that 15 people can comfortably stand in an area 40 square feet.

Now, we know that 1 yard is equal to 3 feet.

Hence, the area of the section 400yds by 200 yds is equal to

Now, in 40ft^2, 15 people can stand comfortably.

Hence, in 720000 ft^2, number of people can stand comfortably is

**Therefore, 270000 people can stand in the park of dimension 400 yds by 200 yds**

Solution 2

If you multiply all those numbers you will get 5.76e9 yds

Question

Which expression is not equivalent to the following expression? 15 - 3 + 15 - 3 - 3 + 15
A. 3(15 - 3)
B. 3(15)
C. 3(15 + 3)
D. 3(12)

Solution 1

In the above problem: it appears that the original expression is equal to 36.

A. 3(15-3) = 3(12)=36

B. 3(15) = 45

C. 3(15+3) = 3(18)=54

D. 3(12) = 36

So it looks like choices A and D are equivalent to the original expression.

A. 3(15-3) = 3(12)=36

B. 3(15) = 45

C. 3(15+3) = 3(18)=54

D. 3(12) = 36

So it looks like choices A and D are equivalent to the original expression.

Solution 2

**Answer: D**

Question

Anna and Alice share a rectangle bedroom that is 18 feet long and 14 feet wide. they split the room into two halves by placing a piece of tape from the northwest corner of the room to the southeast corner of the room. what is the area of each girls half of the room?

Solution 1

The area of the whole room = 14 × 18 = 252

Since they divide it by half, divide the are by 2.

252 ÷ 2 = 126

**Answer = 126 ft²**

Hope this helped☺☺

Since they divide it by half, divide the are by 2.

252 ÷ 2 = 126

Solution 2

126 is the area of one hafe of the room

Question

Rhombus A has base of 7 inches and an area of 35 square inches. Rhombus B has a Base and Height that are three times the base and height of Rhombus A. Find the area of Rhombus b and compare it to the area of rhombus A Explain

Solution 1

Rhombus A:

Area = 35 square inches

base = 7 inches

height = 5 inches

Rhombus B:

Area = 315 square inches

base = 21 inches (7**x 3)**

height = 15 inches (5**x 3**)

A = 21 x 15

The area of Rhombus B is 9 times bigger than the area of Rhombus A. The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.

Area = 35 square inches

base = 7 inches

height = 5 inches

Rhombus B:

Area = 315 square inches

base = 21 inches (7

height = 15 inches (5

A = 21 x 15

The area of Rhombus B is 9 times bigger than the area of Rhombus A. The reason is that 2 dimensions were tripled, so x3 x3 = 9 times bigger.

Question

16 students joined the soccer club. 5/8 of those students were boys. How many boys joined the soccer club?

Solution 1

5/8 is also equal to 10/16, so out of 16 students, 10 were boys. Multiply the numerator and denominator by 2 to find 10/16, and that is how you find the answer.

Solution 2

10 boys joins the soccer club

Question

Lucy created a design with different shapes. Stars made up 1/4 of all the shapes in the design. Eight ninths of the stars are red. What fraction of all the shapes are red stars?

Solution 1

Stars = 1/4

Red stars = 8/9

Multiply:

1/4 × 8/9 = 8/36 = 4/18 = 2/9

**Answer = 2/9**

Hope this helped☺☺

Red stars = 8/9

Multiply:

1/4 × 8/9 = 8/36 = 4/18 = 2/9

Hope this helped☺☺

Question

Convert from radians to degrees -7pi/2

Solution 1

Π=180⁰

-7π/2=(-7*180)/2=-7*90=-630⁰

**-7π/2= -630⁰**

-7π/2=(-7*180)/2=-7*90=-630⁰
