Please help me solve this Question Explanation will be appreciated.

Answer:

9 and 5.

Step-by-step explanation:

So we have the expression:

[tex]9+5+7x^2+3x^2y+2x^2[/tex]

In order to combine like terms, the variables must be exactly the same: not one less, not one more.

3x²y and 2x² cannot be combined because the first value has a y.

7x², 3x²y, and 2x² also cannot be combined because the second value has a y.

9 and 5 is the only one that can be combined because they are just integers. They can be added to be 14.

2, 3, 5, and 9 cannot be combined because the 2 and the 3 are tied to the variables as coefficients. They are not constants.

To combine like terms, we can combine numbers with the same power and variables.

We are given the equation: 9 + 5 + 7x^2 + 3x^2y + 2x^2

We can combine 9 and 5 because they are whole numbers by themselves.

We can combine 7x^2 and 2x^2 because they are whole numbers that both have a variable (x) and the same power.

We can't combine anything to 3x^2y because no other number has these features.

Best of Luck!

A term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

A term in an expression is a set of constant or numerical values, variables, and exponents. Each term of an expression is differentiated from others by a mathematical operation. For example, in the expression 2x²+6x-5, 2x², 6x, and -5 all three are terms and it is differentiated from others by the '+' and '-' operators.

The coefficient of a term is the numerical value present in the term. Let's understand this with the similar example above.

In term 2x², 2 is the coefficient.

In term 6x, 6 is the coefficient.

Hence, a term is an expression is a set of constants, variables, and exponents, while the coefficient of a term is the numerical value present in the term.

Answer:

7 5/6

Step-by-step explanation:

Since you're a subtracting a negative, ti cancels each other out and ends up in addition. So it's 5 1/6+2 2/3. And to add fractions the denominators must be the same.

Thus, you multiple 2/3 * 2= 4/6. So 5+2=7.

And 1/6+4/6=5/6.

Therefore the answers is 7 5/6.

In the first term, 5 is a

In the second term (3y + 13) is a

In the third term. -1 is a

Answer:

Kindly check explanation

Step-by-step explanation:

Given the expression : 5x - 8(3y + 13) - 1

In the first term :

5 a Coefficient, which is the numerical value which exists before and multiplying a variable usually in an algebraic expression. Hence since 5 exists before the variable x, then 5 is the Coefficient of x.

(3y + 13) is a factor in the expression 8(3y + 13), it was used to get a simplified form of the initial expression 24y + 104

-1 is a constant term in the algebraic expression as it has no variable attached to it

Answer:

b = -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6b+14=−7−b

6b+14=−7+−b

6b+14=−b−7

Step 2: Add b to both sides.

6b+14+b=−b−7+b

7b+14=−7

Step 3: Subtract 14 from both sides.

7b+14−14=−7−14

7b=−21

Step 4: Divide both sides by 7.

[tex]\frac{7b}{7} = \frac{-21}{7}[/tex]

b= -3

Answer:

b=−3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6b+14=−7−b

6b+14=−7+−b

6b+14=−b−7

Step 2: Add b to both sides.

6b+14+b=−b−7+b

7b+14=−7

Step 3: Subtract 14 from both sides.

7b+14−14=−7−14

7b=−21

Step 4: Divide both sides by 7.

Answer:

3x=96

Step-by-step explanation:

From the information given, you can write the following:

a+x=96 (1)

a=2x (2)

where a is the number of CDs that Sue has and x is the number of CDs that Gwen has.

You can replace 2 in 1 and you would have the following:

2x+x=96

3x=96

From this, you can isolate x to find its value:

x=96/3

x=32

According to this, the equation that could be used to find the number of CDs, x, that Gwen has is: 3x=96.

Answer: g(-3) is 9 .

Step-by-step explanation:

So there are two functions  and  the first function says that to get the solution x has to be greater than 4   and -3 which is the input is not greater than 4  so you can't use that function to solve for g(-3).

using the second function , it says that  x has to be less or equal to 4. And -3 is indeed less than 4 so you have to use the second function to solve for g(-3)  

g(x) = -2x + 3     Input -3  and solve

g(-3) = -2(-3) + 3

g(-3) = 6 + 3

g(-3) = 9

1/20

Step-by-step explanation:

10 x 2 = 20

the both have 20 and it's the first they have in common so that's the common denominator

2/20 , 5/ 20  are the renamed denominators. Find calculations below

Find the renamed fractions

Information we have

Fractions = [tex]1/10 , 1 / 4[/tex]

As LCM ie least common multiple of denominators 10 & 4 = 20

So, multiplying numerator & denominator of [tex]1 / 10[/tex]  with 2, we get

[tex]( 1 X 2 ) / ( 10 X 2 ) = 2 / 20[/tex]

Similarly, multiplying numerator & denominator of [tex]1 / 4[/tex] with 5, we get

[tex]( 1 X 5 ) / ( 4 X 5 ) = 5 / 20[/tex]

Hence, renamed fractions with common denominators are [tex]2 / 20 , 5 / 20[/tex]

Answer:

50⁰

Step-by-step explanation:

Add 130 plus 50 to get 180.

Answer:

x = 50°

Step-by-step explanation:

In a parallelogram consecutive angles are supplementary, thus

∠ BAC + ∠ ABD = 180°, that is

130° + ∠ ABD = 180° ( subtract 130° from both sides )

∠ ABD = 50°

Since ACDB and FGHE are congruent then corresponding angles are congruent, thus

∠ FEH = ∠ ABD = 50° =x

Answer:

65.41

Step-by-step explanation:

65.3 cm³ is the amount of water filled in the balloon.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that Haley fills a balloon with water until it becomes a sphere with a diameter of 5 centimeters.

We need to find how much water does the balloon contain

It means we need to find the volume of the sphere with diameter 5 centimeters.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

Volume of Sphere=4/3πr³

As diameter is 5

Radius=Diameter/2=5/2=2.5 cm

Volume=4/3×3.14×(2.5)³

=1.33×3.14×15.625

=65.25

=65.3

Hence, 65.3 cm³ is the amount of water filled in the balloon.

The greatest number of sandwiches she can make using 8 cups of canned tuna is D...16 sandwiches.

Answer:

B is the right answer.

Step-by-step explanation:

56 + 0.08x = 164

0.08x = 164 - 56

0.08x = 108

0.08x/0.08 = 108/0.08

x = 1,350

To confirm that:

56 + 0.08x

56 + 0.08(1,350)

56 + 108

= 164

164 is the answer.
