# How do you solve 5x - 10 = 3x + 2

Answer: 5x - 10 = 3x + 2

Subtract 3x over to 5x
Add 10 over to 2

2x = 12

Divide both sides by 2 to get x by itself

x = 6
Answer: 5x - 10 = 3x + 2

5x = 3x + 12

2x = 12

x = 6

Fernando was at the store and i had to buy 4 items but each item cost 1.99 how much did everything cost?

\$7.96

Step-by-step explanation:

4 times 1.99 equals 7.97

\$7.96

Step-by-step explanation:

since each item cost \$1.99 you can multiply by 4

4(1.99)= 7.96

or you can add 1.99 together four times

1.99+1.99+1.99+1.99=7.96

What is the missing constant term in the perfect square that starts with x^2+18x

To make it a perfect square we must add 81 to the expression.

Perfect square

A perfect square is a number that is the result of the product of another number by itself.

For example, 9 is a perfect square as it is the product of 3 and 3.

9 = 3 x 3

Given to us,

at the blank space, there must be some constant so that the equation can be a perfect square.

We know that a perfect square is given as,

Comparing both the equations, we find out that

a² = x²,

2ab = 18x,

a²=x²,

a=x

substituting a's value in 2ab = 18x,

therefore,

Hence, to make it a perfect square we must add 81 to the expression.

How do you write 9/10 as a decimal?

Hey there!

In order to turn a fraction into a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.

So,
as a decimal would be 0.9. Simply divide 9 by 10

Thank you for being part of the Brainly community!
The answer will be 0.9 because just do 9÷10=0.9
To turn a fraction to a decimals you only have to divide the numerator to the denominator.

The interior angle sum of a convex polygon is 1,980°. How many sides does the polygon have? If it is a regular
polygon, what is the measure of each angle? Round to
the nearest tenth, if needed.

Step-by-step explanation:

Formula for finding the internal angle of a regular polygon is

( 2n - 4 )right angle triangle or

( 2n - 4 )90°, it can also be broken down by factorizing the expression since 2 is common,

( n - 2 )180 or supplementary

Now to find the value of n which correspond to the number of sides the polygon has, we equate the formula to the angle sum of the polygon.

( n - 2 ) × 180° = 1980°

open the bracket

180n° - 360° = 1980°

180n°            = 1980° + 360°

= 2340

To find n, divide by 180 which is the coefficient of n

n   = ²³⁴⁰/₁₈₀

= 13

The polygon has 13, sides

To find the measure of each angle,

Recall, the sum total of external angle  = 360⁰

Therefore, to find the value of each of the angles, we divide 360 by n which is 13

³⁶⁰/n

= ³⁶⁰/₁₃

= 27.69⁰

Hey, just adding on to the answer below. Not sure if this is correct for everyone, but it was for me.

Sides: 13 sides

Measure of each angle: 152.3

Step-by-step explanation:

Since we know the sum of the measures of the interior angles of a convex polygon to be 1,980, we can use the angle-sum theorem formula:

(n-2)180=?

to get our answer.

Equation:

(13-2)180 = 1,980

From here we continue using the angle sum theorem but instead with the intent of finding the measure of each individual interior angle (They will all be equal to the same degree)

Use formula

(n-2)180

n

Equation:

(13-2)180

13

This will give you the answer 152.3.

Sorry if this doesn't explain everything correctly or enough, but I hope I helped. :D

(Btw, if you want more of an explanation as how to properly use formulas to get the number of sides, you can go and check out the answer before mine! It really helps, this answer was mainly to just explain the second answer the way I did it that gave me the correct answer!)

The expression 35 + 45x represents a train's distance, in miles, from a terminal after x hours of travel. How far was the train from the terminal at the beginning of its journey? Enter your answer in the box.

At the beginning of the journey, it was 35 miles from the terminal. This can be found, by looking for the constant (35 in this case), which shows that it will never be changed.

hope this helps
