Answer:

Step-by-step explanation:

Since it is only addition and subtraction, you can rearrange the order of the equations. This is what the three eqautions will look like after the arrangement:

1.6z + 8.3 z = ? (9.9z)

6.2y - 5.1y = ? (1.1y)

4.3x + 5.5x = ? (9.8x)

Then you just add and subtract.

Answer:

the answer is D

Step-by-step explanation:

{4x+3y=34

{2x+y=16

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The system of equations to find the cost of large and small candles are,

4x + 3y = 34

2x + y = 16

Option D is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 4 - 8 is an equation.

We have,

At Yankee Candle, four large candles and three small candles sell for $34. For two large candles and one small candle, the cost is $16.

Large candles = x

Small candles = y

Now,

4x + 3y = 34

2x + y = 16

Thus,

The system of equations to find the cost of large and small candles are,

4x + 3y = 34

2x + y = 16

Option D is the correct answer.

D. in Step 3

Answers

Answer:(b) step 1

Step-by-step explanation:

The wrong step in the student's workings is step 1

How to determine the wrong step?

The equation is given as:

x^2 - 2x - 8 = 0

Expand the equation

x^2 + 2x - 4x - 8 = 0

Factorize the equation

x(x + 2)- 4(x + 2)

Factor out x + 2

(x - 4)(x + 2) = 0

The above means that the factored equation of x^2 - 2x - 8 = 0 is (x - 4)(x + 2) = 0

This means that the step 1 of the student's step is wrong and incorrect

Is x + 5 a factor of P(x) = x ^ 3 + 4x ^ 2 + 2x + 35

Answers

Answer:

yes

Step-by-step explanation:

If ( x + 5) is a factor of p(x) then p(- 5) = 0

p(- 5)

= (- 5)³ + 4(- 5)² + 2(- 5) + 35

= - 125 + 100 - 10 + 135

= 0

Since p(- 5) = 0 then (x + 5) is a factor of p(x)

Answer:

(x +5 ) is a factor

Step-by-step explanation:

x + 5 = 0

x = -5

P(x) = x³ + 4x² + 2x + 35

P(-5) = (-5)³ + 4*(-5)² + 2*(-5) + 35

= -125 + 4*25 - 10 + 35

= -125 + 100 - 10 + 35

= -25 -10 +35

= -35 + 35

= 0

P(-5) = o. So, (x +5 ) is a factor

Solve for x, using the exterior angle theorem.

Answers

Answer:

x=121 degrees

Step-by-step explanation:

The extetior angle theorem states that one exterior angle is equivalent to the sum of the opposite two interior angles. So, we can say that x is the sum of the opposite two interior angles, (53 and 68), and 53+68=121.

Need to know the following angle

Answers

Given:

[tex]m\angle A=(2x-15)^\circ[/tex]

[tex]m\angle B=(x-5)^\circ[/tex]

[tex]\text{Exterior}\ m\angle C=148^\circ[/tex]

To find:

The [tex]m\angle ABC[/tex].

Solution:

In triangle ABC,

[tex]\text{Exterior}\ m\angle C=m\angle A+m\angle B[/tex] [Exterior angle theorem]

[tex]148=(2x-15)+(x-5)[/tex]

[tex]148=3x-20[/tex]

[tex]148+20=3x[/tex]

[tex]168=3x[/tex]

Divide both sides by 3.

[tex]\dfrac{168}{3}=x[/tex]

[tex]56=x[/tex]

Now,

[tex]m\angle ABC=(x-5)^\circ[/tex]

[tex]m\angle ABC=(56-5)^\circ[/tex]

[tex]m\angle ABC=51^\circ[/tex]

Therefore, [tex]m\angle ABC=51^\circ[/tex].
