Please Answer This Question With Equation Will Give 20 Points And Mark Brainliest

Answers

Answer 1

Hello there!

Given the equation below:

[tex] \displaystyle \large{ \frac{3x + 3}{2} = 9}[/tex]

Our first step is to get rid of the denominator by multiplying the whole equation by 2.

[tex] \displaystyle \large{ \frac{3x + 3}{2} \cdot 2 = 9 \cdot 2} \\ \displaystyle \large{ 3x + 3 = 18}[/tex]

Isolate x-term - first, we subtract 3 both sides.

[tex] \displaystyle \large{3x + 3 - 3 = 18 - 3} \\ \displaystyle \large{3x= 15} \\ [/tex]

Divide both sides by 3 to leave only x-term.

[tex] \displaystyle \large{ \frac{3x}{3} = \frac{15}{3} } \\ \: \displaystyle \large{x = 5}[/tex]

Therefore, the value of x is 5.

Checking Answer

Optional Step:

First, we substitute x-value that we got in the equation.

[tex] \displaystyle \large{ \frac{3x + 3}{2} = 9} \\ \displaystyle \large{ \frac{3(5)+ 3}{2} = 9}[/tex]

Evaluate the expression.

[tex] \displaystyle \large{ \frac{15 + 3}{2} = 9} \\ \displaystyle \large{ \frac{18}{2} = 9} \\ \displaystyle \large{ 9 = 9}[/tex]

Since both sides are equal. The equation is true!

Answer

Hence, x = 5.

A number increased by 10 is 32. How would I write that as an equation?

Answers

Answer:

4.

Step-by-step explanation:

Remember that “of” means multiplication, so from your question we infer the following equation:

(1/2)x + 10 = 12

First, subtract 10 from both sides:

(1/2)x = 2

Multiply both sides by 2 to eliminate the fraction:

x = 4

Now substitute for x in the original equation to prove this:

(1/2)x + 10 = 12

x = 4

(1/2)4 + 10 = 12

4/2 + 10 = 12

2 + 10 = 12

12 = 12

So the number, x, is 4.

it is an example of your question.

h=54+1/2at^2 solve for a
Im lost on if I should square the 1/2at first?

Answers

Answer:  a = (2h-108)/(t^2)

Other answer formats are possible.

===========================================================

Explanation:

Let's say we want to solve the equation h = 54 + 10a for the variable 'a'. This is relevant to the problem at hand don't worry.

What we'd do is two things

Subtract 54 from both sides Divide by 10

So the steps look like this

h = 54 + 10a

h-54 = 10a

(h-54)/10 = a

a = (h-54)/10

Now let's say we wanted to solve this equation: h = 54 + ca, where c is a constant and can stand in place of any number. The steps would be pretty much identical. Instead of dividing both sides by 10, we divide both sides by c. We can do this as long as c isn't zero of course.

That means the equation h = 54+ca solves to a = (h-54)/c

---------------------------

Why did I do those examples? To build up to the equation your teacher gave you.

Let's replace c with 0.5t^2

This is because 1/2 = 0.5

The 1/2at^2 is the same as (1/2t^2)a

So instead of a = (h-54)/c, we'd get a = (h-54)/(0.5t^2)

As a last optional and encouraged step, we can multiply every term by 2 to get rid of that decimal value.

Doing so makes a = (h-54)/(0.5t^2) turn into a = (2h-108)/(t^2)

---------------------------

Here's another way to solve:

h = 54 + (1/2)at^2

h-54 = (1/2)at^2

2(h-54) = at^2

2h-108 = at^2

(2h-108)/(t^2) = a

a = (2h-108)/(t^2)

In the second step, I subtracted 54 from both sides. Immediately afterward, I multiplied both sides by 2 so I could clear out the fraction. Then I divided both sides by t^2 to fully isolated the variable 'a'.

At Chase Bank, you earned $50 in interest last year. If the interest rate is 4.5% and
your money was in the account for one year, what was your principal deposit, rounded to
the nearest dollar?

Answers

Answer:

$1,111

Step-by-step explanation:

Let x = principal amount

x multiplied by 1.045 will equal the final amount

Since 50 was earned, x + 50 will also equal the final amount

1.045x = x + 50

Let's move the x terms to left side by subtracting both sides by x

1.045x = x + 50

- x        - x

0.045x = 50

Divide both sides by 0.045 to isolate the x variable

0.045x/50 = 50/50

x = 1,111.111111111

To convert the measurements of metric system into another units of metric system we have to either multiply it by 10, 100, 1000, 10000, 100000, etc or divide by 10, 100, 1000, 10000, 100000, etc.

If we have to convert bigger unit into smaller unit then we have to multiply the unit by the multiples of 10, then the decimal point is shifted to right by 1 or 2 or 3 or 4 , etc. places.

For example, 1.2 kg is converted into g so we have to multiply it by 1000, so decimal point is shifted to right by 3 places, i.e.,

1.2 x 1000 = 1200 g

If we have to convert smaller unit into bigger unit then we have to divide the unit by the multiples of 10, then the decimal point is shifted to left by 1 or 2 or 3 or 4 , etc. places.

For example, 12 cm is converted into m so we have to divide it by 100, so decimal point is shifted to left by 2 places, i.e.,

12 / 100 = 0.12 m

Answer:

30+(2x+7)+63=180(sum of angles of triangle )

30+2x+7+63=180

2x+100=180

2x=180-100

x=80/2

x=40

Answer:

[tex]\boxed {\boxed {\sf (2x+7)+30+63= 180}}[/tex]

[tex]\boxed {\boxed {\sf x=40}}[/tex]

Step-by-step explanation:

We are asked to write an equation to solve for x and use the equation to find x.

We know that the angles in a triangle must add to 180 degrees. Therefore, the sum of the three angles in this triangle: 30, 63, and (2x+7) must equal 180. We can set up an equation.

[tex](2x+7)+ 30 +63= 180[/tex]

Now we can use the equation to solve for x. First, we combine like terms on the left side of the equation. The 3 terms without variables or constants can be added.

[tex]2x+ (7+30+63)= 180[/tex]

[tex]2x+ (100)= 180[/tex]

We are solving for x, so we must isolate the variable. 100 is being added to 2x. The inverse operation of addition is subtraction. Subtract 100 from both sides of the equation.

[tex]2x+100-100= 180-100 \\2x=180 -100 \\2x=80[/tex]

x is being multiplied by 2. The inverse operation of multiplication is division. Divide both sides of the equation by 2.

[tex]\frac {2x}{2}= \frac{80}{2}[/tex]

[tex]x= \frac {80}{2} \ \\[/tex]

[tex]x=40[/tex]

The equation is (2x+7)+ 30+63= 180 and x is equal to 40.

Skye wants to buy 3 erasers each for her 4 best friends. If erasers cost $0.72 each, how much money does Skye need?

Answers

Answer:

3 x 4 = 12 erasers   12 x $0.72 = $8.64

Step-by-step explanation:

Answer: Skye will need $8.64

Step-by-step explanation:

We can start by seeing how many erasers she needs in total. We can multiply the 3 erasers for all 4 of her friends.

3 x 4 = 12 Erasers

Now we multiply the cost of one eraser by the total amount she needs, 12.

0.72 x 12 = 8.64

So the amount of money Skye needs for all her friends to have 3 erasers is $8.64
