Explain how to solve the equation and how to check the solution.
40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
equations by using inverse operations, including squares, square roots, cubes, ... A pair of inverse operations is defined as two operations that will be ... The following examples summarize how to undo these operations using their ... x is divided by 2, so we multiply by 2 on both sides. 2. 8 2. 2 x. ∙ = ∙. Solution: 16. explanation:

Step-by-step explanation:
Answer:
B,C, E, F
Step-by-step explanation:
B : 5+3 x 4. first you do 3 x 4 which is 12 the + 5 which equals 17
C: I-6+4I first you do -6 + 4 which equals -2 but it is absolute power so it is 2
E: 2 x 2 x 2 x 2 x 2 is 32
F: 12 divded by 4 is 3, so then 3 x 3 is 9
The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle
the measure of an angle is 12 degrees. what is the measure of its supplement
Answer:
168
Step-by-step explanation:
Supplementary angle is two angles that total 180 degrees.
180-12=168
The diagonal of a TV is 42 inches. The base is 38 inches wide. How tall is the Tv? Round your answer to the nearest tenth. Put your answer in the box. EX: 10
Answer:20.6 inches
Step-by-step explanation:
The diagonal measure of a rectangular TV screen is 42 inches. The width of the screen is 36.6 inches.
The diagonal , width and height forms a right angle triangle
So we apply pythagorean theorem
Diagonal is the hypotenuse
LEt the height of the screen is 'h'
c^2= a^2 + b^2
42^2= 36.6^2 + h^2
Subtract 36.6^2 from both sides
h^2 = 424.44
Take square root on both sides
h=20.60194
Round to nearest tenth
Height of the screen = 20.6 inches
Answer:
1,600 inches
Step-by-step explanation:
You need to take the height of the tv and the base of the tv. So you need to take 42x38= 1,596. Now you need to round to the nearest tenth. So take 1,596 and the nearest tenth would be 1,600. Because 1,596 is closer to 1,596 then 1,590.

Step-by-step explanation:
Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

Mrs. Little would like to set up each station to be able to make 64 pancakes. How many teaspoons of salt should be measured out for this quantity of pancakes?
(Salt 3/4 tsp of salt)
Answer:
48
Step-by-step explanation:
all you do is 64 times 3/4
48 tsp of salt should be measured for 64 pancakes.
What is Equation?Two or more expressions with an equal sign is called as Equation.
Given,
Mrs. Little would like to set up each station to be able to make 64 pancakes and Salt for 1 pancake is 3/4 tsp.
We need to find how many teaspoons of salt should be measured for 64 pancakes.
1 pancake=3/4
64 pancakes=x
Now, x=3/4×64
x=48.
Therefore 48 tsp of salt should be measured for 64 pancakes.
