Multiply by 5
Add 3
Subtract 3
Divide by 5
Answer:
Subtract 3
Step-by-step explanation:
The first operation that should be done first in the expression 5x + 3 = 28 is subtracting 3 from both sides.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, 5x + 3 = 28.
The first operation that should be done first is subtracting 3 to both the side of the equation to separate the variable x and the constant term.
∴ 5x + 3 - 3 = 28 - 3.
5x = 25.
x = 5.

36 is 0.9% of what number
(not urgent
Answer: 4000
Step-by-step explanation:
If for example 5 is 1% of what number, you would multiply that by 100/1 and multiply that by 5.
For 36 is 0.9% of what number, you would multiply the 36 by 100/0.9 and multiply that by 36.
100/0.9 is 111.11 and 111.11 x 36 is 4000, so 4000 would be your answer.
The probability of choosing a diamond card from a standard pack of cards is 0. 25, what is the probability of choosing any other suit?
Using the probability of complementary events, it is found that there is a 0.75 probability of any other suit.
What is the probability of complementary events?When two events are complementary, the sum of their probabilities are 1.
In this problem, a diamond card and a card for any other suit are complementary events, hence the equation is:
0.25 + p = 1
p = 0.75.
Thus, there is a 0.75 probability of any other suit.

a rectangular is drawn below its perimeter is 4.8 yards what is the measure of each side one side is 2m another side is M another side is 2 m another side is M
Answer with step-by-step explanation:
m = 0.8
Firstly, we have to see how many M's we are dividing. On the image, it shows 2m + 2m + m + m = 6m. Then, we divide 6 by 4.8, since is would give us the correct value of m. 4.8 ÷ 6 = 0.8.

Please help‼️‼️‼️‼️‼️ Melanie plans to repaint some classroom bookcases.She has 1 7/8
gallons of paint. All of the bookcases are the same size and each requires 3/16 gallon of paint. How many bookcases will she be able to paint
Answer:
The custodian will be able to repaint 7 bookcases with the amount of paint.
Step-by-step explanation:
The custodian has 5 1/4 gallons of paint, to find the number of bookcases the custodian will be able to repaint with this amount of paint if each bookcase requires 3/4 gallons, then we will simply divide 5 1/4 by 3/4 to give us the number.
But first we need to change 5 1/4 to improper fraction,
thus; 5 1/4 =
5 1/4 ÷3/4 = ÷
(We will want to change the division sign to multiplication, to do that, we will have to take the inverse of 3/4 which is 4/3 hence;
= ×
4 will cancel out 4 hence;
=
= 7
Therefore the custodian will be able to repaint 7 bookcases with the amount of paint.

If using the method of completing the square to solve the quadratic equation
x2 -9x + 2 = 0, which number would have to be added to "complete the square"?
Answer:
Add the square of half of the coefficient of [tex]x[/tex] to both sides
[tex]\left(-\dfrac92\right)^2=\dfrac{81}{4}[/tex]
Completing the square:
Rewrite [tex]x^2-9x+2=0[/tex] in the form [tex]y=(x-b)^2 +c[/tex]
Add the square of half of the coefficient of [tex]x[/tex] to both sides:
[tex]\implies x^2-9x+2+\left(-\dfrac92\right)^2=\left(-\dfrac92\right)^2[/tex]
[tex]\implies x^2-9x+2+\dfrac{81}{4}=\dfrac{81}{4}[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 +2=\dfrac{81}{4}[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 +2-\dfrac{81}{4}=0[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 -\dfrac{73}{4}=0[/tex]
[tex]\implies\left(x-\dfrac92\right)^2 -\dfrac{73}{4}=0[/tex]

Questão 02 - Carlos e sua mãe têm juntos atualmente 47 anos. Sabendo que sua mãe ganhou Carlos aos 23 anos, a equação que representa a soma da idade de Carlos com sua mãe é: * (A) 2x = 47. (B) x + 23 = 47. (C) 2x + 47 = 23. (D) x + 2 = 23. (E) 2x + 23 = 47
Answer:
x+23 = 47
Step-by-step explanation:
Let age of Carlos is x. It is mentioned that the sum of age of Carlos and his mother is 47 years old. Age of Carlos is 23.
We need to find the equation that represents the sum of Carlos' age with his mother.
x+23 = 47 is the required equation.
Also, we can find the age of Carlos as :
x = 47 - 23
= 24 years
Hence, the correct option is (B).

Answer:
(i) The surface(sheet) of a conical tent is circular so we must use the formula for the area of a circle to find out;
Given the diameter 14, we must find the radius.
To find the radius we must do 1/2 of the diameter to get the radius.
14 x 1/2 = 7, is the radius
Formula for area of a circle;
a = πr^2
where pi is 3.14 or 22/7, r is the radius which is being squared
Plug in the actual values:
a = πr^2
a = 3.14 x 7^2
a = 3.14 x 49
a = 153.86 square meters, is the area of the conical tent's sheet.
(ii) Since there are 153.86 meters in one sheet, we should multiply that by $12(because $12 per meter) to get the total cost.
So,
153.86 meters x $12 = $1,846.32, it would cost 1,846.32 dollars.
