simplify the equation

Answers

The first one is correct.
It simplifies to 5/3 x plus 2/3 x which equals 7/3 x. This becomes 2 and 1/3 x.
And 8/3 is 2 and 2/3.
The last 2 answers are wrong because 1/3 times -8 gives a negative number.
Remember that when you multiply by 3/3 you change the form but not the number.

if there are 139,799,000 square miles of water on earth what percent is left on earth that is not covered in water

Answers

There are 196.1 million square miles on earth so subtracting 139.8 from that is 57.1 so 57.1 million square miles of earth is not covered with water

The percentage of earth that is not covered in water is given by the equation A = 29 %

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total area of earth be = 196,900,000 square miles

And , 71% of Earth’s surface is covered in water

So ,

Percentage of earth's surface covered in water = 71 %

And , area of earth covered by water = 139,799,000 square miles

Substituting the values in the equation , we get

So , the remaining percentage of earth not covered in water A = 100 - 71

On simplifying the equation , we get

Remaining percentage of earth not covered in water A = 29 %

The remaining area of earth = 0.29 x 196,900,000

The remaining area of earth = 57,101,000 miles²

Therefore , the value of A is 29 %

Hence , the percentage is 29 %

Directions: Solve for x, then find each angle measure

Answers

Answer:

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

so

9x + 3 + 11x - 21 + 5x - 2 = 180

25x = 180 - 3 + 21 + 2

25x = 200

x = 200 : 25

x = 8

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

E = 9 * 8 + 3 = 75°

D = 5 * 8 -2 = 38°

F = 11 * 8 - 21 = 67

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

check

75 + 37 + 67 = 180°

The required simplified value of the x is 8, as of the given condition.

A figure of the triangle is given, from the measures of the angle we have to determine the value of the x.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
As for the property of a triangle, the sum of the angle is 180,
5x - 2 + 11x -21 + 9x + 3 = 180
25x -20 = 180
25x = 200
x = 8

Thus, the required simplified value of the x is 8.

the price of a machine is given as GHC 20,000 plus VAT. If the VAT rate is 12%, find the price that a customer must pay for the machine.

Answers

Answer:

Step-by-step explanation:

12/100 × 20000

= 2400

Price customer must pay = 20,000+ 2400 = 22400.

If price of a machine is given as GHC 20,000 plus VAT. If the VAT rate is 12%. Then 22400 is the price that a customer must pay for the machine.

What is Percentage?

Percentage, a relative value indicating hundredth parts of any quantity.

Given,

The price of a machine is given as GHC 20,000 plus VAT

The VAT rate is 12%,

We need to find how much a customer has to pay for the machine..

12% is changed to decimal number by dividing with 100.

12/100=0.12

Now multiply 20000 with 0.12 to find 12% of 20000

0.12×20000=2400

Now we have to add 2400 with 20000 to get the cost of machine after adding VTA

20000+2400=22400

Hence 22400 is the price that a customer must pay for the machine.

Can someone please tell me how to subtract 1 3/8 by 3/4
Please help!

Answers

Answer:

2 1/8

Step-by-step explanation:

In order to subtract two fractions with unlike denominators, you have to bring them to THE SAME denominator. You can do that by multiplying both the numerator and denominator of 3/4 by 2 (so it can have a denominator of 8) to get 6/8. Then, simply add 1 3/8 and 6/8 by combining the numerators and keeping the denominators the same. You should get 1 9/8 which is, as a mixed number, 2 1/8

A car moving at a constant speed passed a timing device at t = 0. After 6 ​seconds, the car has traveled 534 ft. Write a linear function rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device.

Answers

Answer:

d = 89t

Step-by-step explanation:

d = distance --- t = timing device --- x = speed or feet per x

d = tx

linear equation from this (SOLVE) --> 534 = 6x ---> 89 = x

linear equation --> d = 89t

Answer:

[tex]f(x)=89x[/tex]

Step-by-step explanation:

With the given information, you have 2 points.

1. (0, 0)

2. (6, 534)

With 2 points, you can calculate the slope of the linear function.

[tex]m=\frac{y2-y1}{x2-x1} \\m=\frac{534-0}{6-0} \\m=\frac{534}{6} \\m=89[/tex]

Finally, you can write a function:

[tex]f(x)=mx+b[/tex]

No need to calculate the y-intercept as thats already given in point (0, 0).
