Find The Values Of X And Y By Writing Two Equations And Solving The System Of Equations.

Answers

Answer 1

Answer:

y=2 x=5

Step-by-step explanation:

3x-2y=11

2x-3y=4

you multiply both equations to cancel one variable out. in this case you multiply the first equation by 2 and the second by -3

     6x-4y=22

+    -6x-9y=12

--------------------------

0x+5y=10

y=2

you plug that in either equation

3x-2(2)=11

3x-4=11

3x=15

x=5

The equation that can be used to solve  log₄(x + 4) + log₄(x - 2) = 2 is

What is a logarithm?

The logarithm is the opposite of the exponential function.

This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.

Given, log₄(x + 4) + log₄(x - 2) = 2.

We know logₐx + logₐy = logₐxy.

log₄(x + 4)(x - 2) = 2.

Write the ratio 12 to 18 as a fraction in simplest form.

Answers

x to y can be expressed as a fraction this way: x/y.

Let x = 12

Let y = 18

12/18

We can now reduce to lowest terms.

Dividing 12 and 18 by 6, we get 2/3 as the final answer.

The simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18). Simplifying the fraction ensures that there are no common factors other than 1 between the numerator and the denominator, making it the simplest representation of the ratio.

To express the ratio 12 to 18 as a fraction in simplest form, we can divide both numbers by their greatest common divisor (GCD). The GCD of 12 and 18 is 6. By dividing both numbers by 6, we simplify the fraction to its simplest form:

12 ÷ 6 = 2

18 ÷ 6 = 3

Thus, the simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18).

Robert spends $30.45 before tax at the bookstore. If the sales tax rate in his city is 7.25%, what is the total cost of his purchase?

Answers

Answer:

$32.65 is the answer.

Step-by-step explanation:

First, we must calculate 7.25% of 30.45.

30.45 x 0.0725 = $2.20

Now, we must add this to the original price

$30.45 + $2.20 = $32.65

Therefore, $32.65 is the total cost of his purchase.

Hope this helps! :)

Answer:

$32.66

Step-by-step explanation:

before tax = $30.45

tax sales = 7.25%

total cost = $30.45 x 1.0725

Andre wants to make a scaled copy of jada drawing so the side that corresponds to 4 units in jada polygon is 8 units of his scaled copy Andre says i wonder if i should add 4 units to lengths of all of the segments what would you say in response to Andre explain or show your reasoning

Answers

Answer:

No she should add extra lengths

Step-by-step explanation:

The difference between scaled copy  and jada drawing is that it is in the ratio

8:4

2:1

that is the scaled copy is twice as large as the jada drawing itself.

So every dimension is doubled or made twice as large as the initial measurement. Andre should not add 4 units to all sides instead the drawing is made twice as large . It will serve the same purpose of enlarging the drawing while maintaining its shape. If extra mesurements are added the drawing will be changed.

One runner has run 15 miles this month and plans to run 2 1/2 miles per day for the rest of the month. Another runner has not yet run this month but plans to run 3 1/4 miles per day for the rest of the month. After how many days will the two runners have run the same number of miles?

Answers

Answer:

After 20 days, the two runners will have run the same number of miles

Step-by-step explanation:

The problem can be solved by using equations. However, we'll approach the solution by using pure reasoning and logic, besides calculations.

The first runner has already run 15 miles this month and plans to run 2 1/2=2.5 miles per day for the rest of the month.

The other runner has not yet run and plans to run 3 1/4 = 3.25 miles per day for the rest of the month. Since his running rate is greater than the other runner, they will both eventually have the same number of miles.

The difference in their running rates is 3.25 - 2.5 = 0.75 miles per day. Since the current difference between them is 15 miles, the second runner needs to run for 15 / 0.75 = 20 days.

After 20 days, the two runners will have run the same number of miles
