If 2(x + 3) + 7x = 3(x - 2) - 9, then x = ?

Answer:

X=-7

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

Finding the answer to this expression is very simple.

You can work backwards to find it. First off you need to subtract 5 from both sides :

x + 5 - 5 = -2 -5, in which that will give you,

5 - 5 = 0 and -2 - 5 = -7 so,

x = -7 as simple as that!

Answer:

3 3/8 cups of flour

Step-by-step explanation:

So, we know that 2 1/4 is the normal amount of flour you would use in the recipe. but you don't want to do normal. You want to make 1 1/2 times more than you usually do.

To do this, first figure out what half of 2 1/4 is.

(2 1/4) /2 = 1 1/8

Then, because you are looking to use 1 1/2 times more flour, simply add the 1 1/8 to the 2 1/4

You end up using 3 3/8 cups of flour.

Step-by-step explanation:

Just took the test edge 2020

Melissa made 5 three-point baskets in her basketball game.

Cramer's Rule is a system of linear equation solving technique.

Let's say we're given a system of linear equations.

ax+by=c

dx+ey=f

then, the solution of the equation with the Cramer's rule is given by

[tex]x= \frac{\begin{vmatrix}c&b\\f&e\end{vmatrix}}{\begin{vmatrix}a&b\\d&e\end{vmatrix}}[/tex]

[tex]y= \frac{\begin{vmatrix}a&c\\d&f\end{vmatrix}}{\begin{vmatrix}a&b\\d&e\end{vmatrix}}[/tex]

Let Melissa make 'x' 2-point baskets and 'y' 3-point baskets.
So, as she made a total of 14 baskets we have that

x+y=14

and, as she made a total of 33 points we have that

2x+3y=33

We end up with the system of linear equations.

x+y=14

2x+3y=33

This gives us the matrix equation

[tex]\left[\begin{array}{ccc}1&1\\2&3\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}14\\33\end{array}\right][/tex]

Using Cramer's rule we get

[tex]x= \frac{\begin{vmatrix}14&1\\33&3\end{vmatrix}}{\begin{vmatrix}1&1\\2&3\end{vmatrix}}=\frac{14 \times 3 - 1 \times 33}{1 \times 3 - 1 \times 2} = \frac{42 - 33}{3-2}=\frac{9}{1} =9[/tex]

[tex]y= \frac{\begin{vmatrix}1&14\\2&33\end{vmatrix}}{\begin{vmatrix}1&1\\2&3\end{vmatrix}}=\frac{1 \times 33 - 14 \times 2}{1 \times 3 - 1 \times 2} =\frac{33-28}{3-2}= \frac{5}{1} =5\\[/tex]

Hence, Melissa made (y=)5 three-point baskets in her basketball game.

The intersection of two planes contains at lease two points

What is intersection of two planes?

When two planes intersect, they form a line.

The vector equation for the line of intersection is given by

r = r​₀ ​+ tₓ

where r₀​​ is a point on the line

tₓ is the cross product of the normal vectors of the two planes.

The parametric equations for the line of intersection are given by

x = a , y = b and z = c

where a, b and c are the coefficients from the vector equation

r = a (i) + b (j) + c (k)

The line of intersection will be perpendicular to the normal of both the planes

The line of intersection lies on both the planes

Therefore , a line is observed at the intersection of two planes

Hence , the intersection of two planes always contains at least two points and it forms a line

f(a + 2) for f(x) = (3 + x) / (x - 3)

Substitute a + 2 for x in our equation

f(a + 2) = (3 + (a + 2)) / ((a + 2) - 3)

Combine like terms

f(a + 2) = (5 + a) / (a - 1).

Answer:

36.2

Step-by-step explanation:

144.8/4 = 36.2

The answer is 36.2 when 144.8 divided by 4.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

/ Division operation: Divides left-hand operand by right-hand operand

For example 12/2 = 6

Given that digit as :

If the denominator is 144.8, the numerator can be taken as 4, so the fraction would become as:

⇒ 144.8/4

⇒ 36.2

Hence, the answer is 36.2 when 144.8 divided by 4.

Step-by-step explanation:

The value 2 has 1 tenth or 0.2 and the value 5 has 1 hundredth or 0.05.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The values of the number will be:-

2 x ( 1 / 10 ) = 0.2

5 x ( 1 / 100 ) = 0.05

25 x ( 1/ 100 ) = 0.25
