Solve each equation 7.7r+6=6.7r+6

1 answer:

3 0

You would first put the like terms together
7.7r-6.7r=6-6
Then you solve like a normal problem
1r=0
Then divide 1 from both sides
After that u would get r=0 as the answer

Answer:

Store A has a better deal because $402.90 is less than $404.10.

Step-by-step explanation:

Store A

The $25 off coupon reduces the price to ...

$499 - 25 = $474

The discount from this amount is 15%, so is ...

$474 × 0.15 = $71.10

The final amount paid is then ...

$474.00 -71.10 = $402.90

(Side note: you can select the correct answer at this point, because only one answer shows this value.)

___

Store B

After the $20 off coupon, the price is ...

$469 -20 = $449

The additional 10% discount amounts to ...

$449 × 0.10 = $44.90

So, the final price is ...

$449.00 -44.90 = $404.10

___

Now, you know that Store A offers the better price because $402.90 is less than $404.10.

Answer:

Part 1) $y=32.5x+11.95$

Par 2) see the explanation

Part 3) $\$401.95$

Step-by-step explanation:

Part 1) Write an equation in slope intercept form to represent this problem

Let

x ----> the number of tickets

y ---> the total cost

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept (one-time processing fee)

In this problem we have

$b=\$11.95$

ordered pairs (4,141.95) and (7,239.45)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values in the formula

$m=\frac{239.45-141.95}{7-4}$

$m=\frac{97.5}{3}$

$m=32.5$

substitute the values in the linear equation

$y=32.5x+11.95$

Part 2) What does your slope represent in this problem? What does your y-intercept represent in this problem?

a) The slope of the linear equation represent the unit rate, so the slope represents the cost of one ticket

$m=\$32.5\ per\ ticket$

b) The y-intercept is the value of y when the value of x is equal to zero

In this context, the y-intercept represent the one-time processing fee

$b=\$11.95$

Part 3) Use the equation to find how much Alan would have to pay for 12 tickets

For x=12 tickets

substitute in the linear equation

$y=32.5(12)+11.95$

$y=\$401.95$

The figure below shows two half-circles at the ends of a rectangle with the dimension shown.

timurjin [86]

Answer:

D. 154

Step-by-step explanation:

The area of the rectangle is 15*5= 75 inches

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633

75 + 78.53981633 is about 154

Answer:

$-7 < -4 < 0 < 7$

Step-by-step explanation:

Given

Change: -4, 7, -7 and 0

Required

Compare them

From the list of given options, we can observe that the inequality < is used in all options.

This implies that we arrange from least to highest

The least is -7

Then, -4

Then 0

And lastly, 7

So, we have:

$-7 < -4 < 0 < 7$
