Answer:

5w + 15

$45

Step-by-step explanation:

(6)*(5) + 15 = $45

The amount of money Nayeli would have saved in W weeks is given by the equation A = 5W + 15

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

After one week of saving, Nayeli will have:

$15 + $5 = $20

After two weeks of saving, Nayeli will have:

$20 + $5 = $25

Continuing this pattern, we can find that after six weeks of saving, Nayeli will have:

$15 + 6($5) = $45

So, after six weeks of saving, Nayeli will have $45.

Amount saved = starting amount + (amount saved per week) × (number of weeks)

Amount saved = $15 + ($5)W   be equation (1)

So, the expression that represents the amount of money Nayeli would have saved in W weeks is

A = $15 + ($5) W

Hence , the equation is A = 5W + 15

Answer:

4

Step-by-step explanation:

So, since we already know x = 1, we just need to figure out what 3 x 1 is. (Since there's no space between the 3 and the x, 3x would be 3 times x.)

3 x 1 = 3.

So, our "new equation" is:

1 + 3

Add them together to find the answer:

1 + 3 = 4

4 is your answer.

Explanation:

y = mx + b Calculate the slope, m, from the given point values, solve for b by using one of the point values, and check your solution using the other point values.

A line can be thought of as the ratio of the change between horizontal (x) and vertical (y) positions. Thus, for any two points defined by Cartesian (planar) coordinates such as those given in this problem, you simply set up the two changes (differences) and then make the ratio to obtain the slope, m.

A line has the general form of y = mx + b, or vertical position is the product of the slope and horizontal position, x, plus the point where the line crosses (intercepts) the x-axis (the line where z is always zero.) So, once you have calculated the slope you can put any of the two points known into the equation, leaving us with only the intercept 'b' unknown.

Answer:

$600

Step-by-step explanation:

1 week = $20

30 weeks = 20 x 30 = $ 600

The saving of 30 weeks would be an amount of 600 dollars.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

George makes $20 doing lawn work for 4 hours each week.

He has been saving this money for 30 weeks

The saving of one week = $20

The saving of 30 weeks = $20 × 30

Apply the multiplication operation to get

The saving of 30 weeks = $600

Alternative method :

According to the given situation, we can write a ratio as

one week : 20 dollars = 30 weeks : x dollars

⇒ 1 / 20 = 30 / x

Apply the cross-multiplication operation,

⇒ 1 × x = 30 × 20

Apply the multiplication operation to get

⇒ x = 600

Hence, the saving of 30 weeks would be an amount of 600 dollars.

Answer:

x = 62

Step-by-step explanation:

The triangle is isosceles. That means two sides are equal. The angles opposite those equal sides are also equal.

Every triangle has 180 degrees.

The unmarked angle is also x.

x + x + 56 = 180             Combine the left

2x + 56 = 180                 Subtract 56 from both sides

2x = 180 - 56

2x = 124                         Divide by 2

2x/2 = 124/2

x = 62

Step-by-step explanation:

This is a Fibonacci sequence. Basically, the next term is the sum of the 2 previous terms.

Notice the third term, it's the sum of 2 and 1.

Notice the fourth term, it's the sum of 3 and 2.

Each term follows the same pattern.

[tex]p-5(p+4) = p-(8-p)\\\\\implies p-5p - 20 = p-8+p\\\\\implies -4p-2p = 20 -8 \\\\\implies -6p = 12 \\\\\implies p = -2[/tex]

Answer: To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.

Answer:

Step-by-step explanation:

We can form an equation from the two given points.

The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

We can calculate the slope from the two given points, (10,0) and (0,-15). Slope is Rise/Run, where Rise is the change in y and Run is the change in x.

From the two given points, starting at (0,-15) and ending at (10,0):

Rise = (0-(-15)) = +15

Run = (10-0) = 10

Rise/Run (slope) = 15/10 or 1.5

The equation becomes y = (1.5)x + b

We know b, since it is the value of y when x=0. The point (0,-15) says -15 when x=0. You can also can find b by entering either of the two given points and solving for b. I'll pick (10,0):

y = (1.5)x + b

(0) = (1.5)*(10) + b

0 = 15 + b

b = -15

The equation is y = (1.5)x - 15
