make x the subject of 4(x-3)/a

Answers

The rearranged form of equation 4(x-3)/a=y will be x=ay+3.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, the expression is, 4(x-3)/a=y

First, we open the bracket to make x the variable in the equation.

4x - 12/a = y

4x - 12 = ay

4x = ay + 12

x = ay + 12/4

x = ay + 3

Thus, the rearranged form of equation 4(x-3)/a=y will be x=ay+3.

How long did it take Mariana to drink all the slushy?

seconds

Answers

The amount of slushy that was originally in the cup is 225 milliliters and the time it took Mariana to drink all the slushy is 50 seconds.

How to find the original quantity?

Total quantity she took

Total quantity = 4.5 × 17

Total quantity = 76.5 milliliters

Original quantity = 148.5 + 76.5

Original quantity = 225 milliliters

b. Time taken to drink all

Time =225 milliliters /2.5

Time = 50 seconds

Joe went to the hobby shop and bought 2 model sports cars at $8.95 each and some paints. If he spent a total of 23.65, what was the cost of the paints? Can you give the equation pleaseee

Answers

If Joe spent a total of $23.65 , then the cost of the paints is $5.75  .

In the question ,

it is given that ,

From the hobby shop , Joe bought 2 model sportscars for $8.95 each

the cost for 2 sports car = 8.95*2 = 17.9

the total amount spent by Joe at the shop = $23.65

let the cost of the paint be "$x" .

the above situation can be represented by the equation .

total cost = cost for 2 model cars + cost of paint

substituting the values from above ,

we get ,

23.65 = 17.9 + x

x = 23.65 - 17.9

x = 5.75

Therefore , If Joe spent a total of $23.65 , then the cost of the paints is $5.75  .

Which equation represents a line with slope of -1/3 and y intercept of 5/3?

A. X-3y=5
B.3x-y=5
C.x+3y=5
D.3x+y=-5

Answers

The equation of line with slope is -1/3 and y intercept 5/3 is : x + 3y = 5.

What is equation of line?A straight line's general equation is y = mx + c, while m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents a equation of a straight line having gradient m and intercept c mostly on y-axis.

In the form of a slope intercept, the line's equation looks like this:

y = mx + b

where

slope = m

y-intercept = b

Here given slope = -1/3

y-intercept at 5/3

As a result, the line's equation has a slope of -1 / 3.

Let's use the locations to determine the y-intercept 5/3.

y = mx + b

Here b = 5/3

By substituting ,

y = -1/3x + 5/3

Multiplying both sides by 3,

3y = -x + 5

3y + x = 5

= x + 3y = 5.

Therefore the equation of line is x + 3y = 5.

For the given pair of intersecting lines, we find out that the value of x is 1 and the measure of the angle 1 is 169°.

From the figure we see that there are two lines intersecting each other.

We know,

Sum of all the angles formed = 360

We also know that

If there are a pair of two intersecting lines, then the vertically opposite angles are equal.

=> 20x+11 = 25x-14

=> 5x = 5

=> x = 1

Substituting the value of x in 20x+11 , we have

20*1 + 11 = 21°

Substituting the value of x in 25x-14 , we have

25*1 - 14 = 11°

It is also known to us that the sum of the adjacent angles of a pair of intersecting lines is equal to 180°. This implies that

11° + 1 = 180°

=> 1 = 180° - 11°

=> 1 = 169°

Thus, for the given pair of intersecting lines, we find out that the value of x is 1 and the measure of the angle 1 is 169°.

What is SAS(Side -Angle-Side) triangle?

"SAS" is when we know two sides and the angle between them.

To solve an SAS triangle we use "The Law of Cosines" to calculate the unknown side.

The Law of Cosines = a² = b² + c² − 2bc cosA

where

'b' and 'c' are two given sides

'A' is the angle between side 'b' and 'c' and

a' is the unknown side which we have to find.

In ΔABC , b=21, c=20, a= AC

By the Cosine law

a² = 21²+20² - 2*21*20 cos90°

a² =441 + 400 - 0 (∵cos 90° =0)

a² = 841

a=√841

a=29= AC.

Now, in ΔCDE, b=8, c=15 and a = CE

By the Cosine law

a² = 8² + 15²- 2*8*15cos90°

a² = 64 + 225 - 0 (∵cos 90° =0)

a²= 289

a = 17 = CE.

AE = AC + CE

AE = 29+17= 46.

Answers

There are 19/9 ounces in each sprinkle of sundae

How to determine the number of ounces of sprinkles on each sundae

From the question, we have the following parameters that can be used in our solution:

Number of sundaes = 4

Ounces of sprinkles = [tex]8\frac49[/tex] ounces

From the above parameter, we can calculate the amount of sprinkles using the constant of proportionality formula

This is represented as

Ounces per sprinkle = Ounces of sprinkles/Number of sprinkles

Substitute the known values in the above equation

So, we have the following equation

Ounces per sprinkle = [tex]8\frac49[/tex]/4

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

Given data ,

The angles of the triangle ABC are

∠A = ( 2x + 10 )°

∠B = ( 4x + 2 )°

Let angle ∠C be y

The sum of ∠A + ∠B + ∠C = 180°  

So ,

( 2x + 10 )° + ( 4x + 2 )° + y = 180°   be equation (1)

Now , we can see that AD is a straight line and C is a point on the line AD

The total angle of C on the line AD is 180°

So , ( 5x + 27 )° + y = 180°

y = 180° - ( 5x + 27 )°   be equation (2)

Substituting the value of equation (2) in equation (1) , we get

( 2x + 10 )° + ( 4x + 2 )° + 180° - ( 5x + 27 )° = 180°

On Simplifying , we get

( 2x + 10 )° + ( 4x + 2 )° - ( 5x + 27 )° = 0

( 2x + 4x - 5x ) + ( 10 + 2 - 27 ) = 0

x - 15 = 0

Adding 15 on both sides , we get

x = 15°

Substituting the value of x in the ∠A , ∠B and ∠C equation , we get

∠A = ( 2x + 10 )°

     = 40°

∠B = ( 4x + 2 )°

     = 62°

∠C = 180° - ( ∠A + ∠B )

     = 180° - 102°

     = 78°

Therefore , the angles of the triangle ABC are 40° , 62° and 78°

The measure of ( 5x + 27 )° is

= ( 5 x 15 + 27 )°

= 102°

Hence , the measure of angles of ( 5x + 27 )° , ( 2x + 10 )° and ( 4x + 2 )° are 102° , 40° and 62° respectively
