Question 4

The error was that in step 2, when distributing -3 into the parentheses, the person did not change the sign of 24 so that it was negative, since a negative number multiplied by a positive number will always make a negative number. Here is the correct way to solve this equation:

[tex]-5x+12-7x=-3(5x+8)\\-12x+12=-3(5x+8)[/tex]

Distrubute -3 into the parentheses

[tex]-12x+12=-15x-24[/tex]

Subtract both sides by 12

[tex]-12x+12-12=-15x-24-12\\-12=-15x-36[/tex]

Add 15x to both sides

[tex]-12+15x=-15x-36+15x\\3x=-36[/tex]

Divide both sides by 3

[tex]\frac{3x}{3} =\frac{-36}{3} \\x=-12[/tex]

Question 5

The error was that 2 was added on both sides in step 5 instead of being subtracted from both sides. Here is the correct way to do it, starting from step 4:

[tex]10=16x+2[/tex]

Subtract both sides by 2

[tex]10-2=16x+2-2\\8=16x[/tex]

Divide both sides by 16

[tex]\frac{8}{16} =\frac{16x}{16} \\\frac{1}{2}=x[/tex]

I hope this helps!

Answer:

Each exterior angle measures 360/19 degrees, approximately 18.9 degrees.

Step-by-step explanation:

Start at one vertex of the polygon and go clockwise.  When you reach the next vertex, you change direction.  At each vertex you change direction by the same angle.  When you are back to the first vertex, and start along the first side, you have completed a full 360 degrees clockwise.  Since there are 19 sides and vertices, you must have turned 360/19 degrees at each vertex.

Answer:

Step-by-step explanation:

The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is

x=(-oo, 9),(9, +oo)

Answer:

D : 10ab√2a+20a√2a

Step-by-step explanation:

well in a brief explanation you need at least two (2) recessive (y) to make one red plant which there is not any so the two dominant plant will come out successfully as a dominant (Y) and there will also be yellow leaves with the one recessive

Here, the yellow leaves are dominant and red leaves are recessive. Then, if they have four offspring, they will not have offspring with red leaves. Hence, option A , zero is correct.

In genetics, a dominant genotype is a genetic trait that is expressed when an individual has one or two copies of the dominant allele.

Here, since yellow leaves (Y) are dominant over red leaves (v), a plant with the genotype Yy will have yellow leaves.

When a plant with the genotype Yy (one dominant Y allele and one recessive v allele) is crossed with a plant with the genotype YY (two dominant Y alleles), the possible gametes from each parent are:

Yy plant: Y gamete or v gamete

YY plant: Y gamete

The possible offspring genotypes and their corresponding phenotypes can be determined using a Punnett square

 | Y | Y

Y | YY| YY

y | Yy| Yy

As shown in the Punnett square, all of the offspring will have the genotype Yy and therefore have yellow leaves. None of the offspring will have the genotype vv required to produce red leaves.

Therefore, the answer is 0 (none of the offspring would have red leaves), Hence, option A is correct.

7 + 3 = 10, difference means the answer to a subtraction problem, not sure I understand the question

Step-by-step explanation:

The given expression (7 + 3) represented in difference form as [tex]7-(-3)[/tex]

Difference of numbers :

We have to express 7 + 3 as difference of two number.

As we know that,

           [tex]a-(-b)=a+b[/tex]

In above expression, (a + b) is difference of two number a and -b.

Similarly,

Answer:

x = 20

F = 46

Step-by-step explanation:

For x :

( 20 )  * 2 = 40

40 + 3 = 43

For degrees F

Add triangles have a angle sum of 180

So you just subtract 180 by the angles in the triangle

180 - 91 = 89

89 - 43 = 46

46 is remaining so it is the missing degrees ( F )

The solution is, the area of the following figure is 360 in^2.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

For this case we have that by definition, the area of a rectangle is given by:

A = l*w

In this case, the rectangle is 18 in side, & 21 in.

then:

A = 18*21

   = 378

On the other hand, the area of a triangle is given by:

A = 1/2 b * h

Where:

b: It is the base of the triangle

h: It is the height

We have according to the figure that:

b = 21 - 17 = 4

h = 18 - 9 = 9

So:

A = 1/2 *4 *9

   =18

Finally, the area of the figure is:

378 - 18

=360

Answer: The solution is, the area of the following figure is 360 in^2.

Step-by-step explanation:

Answer:

The ratio of red to blue would be 60: 6 which can be simplified to 10:1.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1

Ratio is the comparison of two quantities in terms of same units.

Example : If a & b be two numbers, then the ratio is a/b, where b≠0

Let Blue counters = x

Red counters would be = 3 times of blue counters = 3x

There are a total of 120 counters in a box.

First we have to find, the number of red and the number of blue counters:

3x + x = 120

⇒ 4x = 120

⇒ x = 120/4

⇒ x = 30

There are 30 blue counters.

Red counters = 3×30 = 90

Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left in the box.

Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left in the box.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1.
