Which makes the proportion true? AB/?= EF/GH

Answer:

The value of "X" would be 2.

To solve for x, you'd have to get it by itself. To do so, you'd simplify both sides by solv8ng the exonents of each side (2^2 = 4) and (2^3 = 8). This leaves you with 4x = 8, which you'd then divide both sides by 4. Thus getting 2 as a final answer.

Step-by-step explanation:

Answer:

See Below.

Step-by-step explanation:

The sum of an A.P. is given by:

[tex]\displaystyle S_n=\frac{n}{2}(a+x_n)[/tex]

Where n is the number of terms, a is the initial term, and xₙ is the last term.

Therefore:

[tex]\displaystyle S_{30}=\frac{30}{2}\Big(a+x_{30}\Big)=15(a+x_{30})[/tex]

And likewise:

[tex]\displaystyle S_{20}=\frac{20}{2}\Big(a+x_{20}\Big)=10(a+x_{20})\\\\ S_{10}=\frac{10}{2}\Big(a+x_{10}\Big)=5(a+x_{10})[/tex]

Substitute:

[tex]15(a + x_{30}) = 3(10 (a + x_{20}) - 5(a + x_{10} ))[/tex]

Distribute:

[tex]15a+15x_{30}=30a+30x_{20}-15a-15x_{10}[/tex]

Simplify:

[tex]15x_{30}=30x_{20}-15x_{10}[/tex]

Simplify:

[tex]x_{30}=2x_{20}-x_{10}[/tex]

The nth term for an A.P. is:

[tex]x_n=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference.

So, it follows that:

[tex]x_{30}=a+d(30-1)=29d+a\\ x_{20}=a+d(20-1)=19d+a\\ x_{10}=a+d(10-1)=9d+a[/tex]

Therefore:

[tex]29d+a=2(19d+a)-9d-a[/tex]

Which follows that:

[tex]29d+a=38d+2a-9d-a\\ \\ 29d=29d \\\\ d\stackrel{\checkmark}{=}d[/tex]

the graph is pasted

A graph is a structure that resembles a set of items in mathematics, more specifically in graph theory, in which some pairings of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

'C. The sum of four products; there are four terms' is the correct answer

Answer:

She earned $20 in tips.

Step-by-step explanation:

First, you need to work out how much pay she'd get for 12 hours work:

12 x $11.25 = $135 for 12 hours work

Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50

Add both these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

Subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20

Answer:

4 dollars per pair of socks.

Step-by-step explanation:

You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.

Another way to solve this is by forming a linear equation.

y = 4x

Any number plugged into x to represent pairs of socks will give the cost, y.

For example: y = 4(7), which simplifies to y = 28.

This means that for every one pair of socks, it costs four dollars.

Answer:

yes and $4

Step-by-step explanation:

7*4=28

11*4=44

13*4=52

15*4=60

Answer:

The graph of g(x) is a vertical translation of f(x). Although both have the same x coordinates but different y coordinates.

The graph of g is a vertical translation of the graph of f 12 units downward.

Step-by-step explanation:

The equation y=f(x)+k represents that when k is negative, the graph moves downward.

The  complete the sentence is The graph of g is a vertical translation of the graph of f 12 units downward.

Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.

Given:

f(x) = 6x

and, g(x) = 6x – 12.

As, -12 shows the vertical translation of 12 units.

Also, The graph of g(x) is a vertical translation of f(x).

Despite having distinct y coordinates, both objects have the same x coordinates.

So, The graph of g is a vertical translation of the graph of 12 units downward.

The plant grew [tex]12\frac{1}{14}[/tex] inches

Step-by-step explanation:

Operations with Fractions

Felipe planted seeds for a science project. One of the plants grew 6 2/7 inches in the first week and 5 11/14 inches in the second week.

We are required to find the total growth during the two weeks. We have to find the sum of:

[tex]6\frac{2}{7}+5\frac{11}{14}[/tex]

Let's convert both fractions to improper form:

[tex]6\frac{2}{7}+5\frac{11}{14}=6+\frac{2}{7}+5+\frac{11}{14}[/tex]

Adding the integers:

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{2}{7}+\frac{11}{14}[/tex]

Now we find the LCM of 7 and 14 is 14, thus:

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{4}{14}+\frac{11}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{15}{14}=11+\frac{14+1}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=11+1+\frac{1}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=12+\frac{1}{14}[/tex]

Rewriting as a mixed number:

Answer: D. (2,0) and (2,5) have the same x-value by different y-values

In other words, the input x = 2 leads to multiple outputs y = 0 and y = 5 at the same time. A function is where any input leads to exactly one output only (assuming that input is in the domain). So whenever x repeats itself like this is when we don't have a function.

Amount of flour available for Jane = 1 3/4 cups of flour

Amount of flour Jane needs to add to make cookie dough
