How to find x-intercept in the equation y=mx+b

Answer:

$22.50

Step-by-step explanation:

if 3 bags of cat food = 13.50, divide 13.5 by 3 to get the cost of one bag, which is $4.50.

since hes getting 5, we can use 13.50 once and then the price of one bag (4.5) twice for the other two.

so that would be 13.5 + 4.5 + 4.5 = $22.50

hope this helped :)

Answer:

cost of three bags of cat food = 13.50

cost of 1 cat food = 13.50/3 = 4.50

cost of 5 cat food = 4.50*5 = 22.5

Answer:

63.6 m^2

Step-by-step explanation:

A = (pi)r^2

r = d/2 = 9 m / 2 = 4.5 m

A = (3.142)(4.5 m)^2

A = 63.6 m^2

Step-by-step explanation:

Answer:

x = 18/25, y = -198/25

Step-by-step explanation:

Given the system of equations:

2x – y = 13x

-3x + 2y= -18

You can combine these two equations effectively by multiplying the first equation by 2, and adding because -2y and 2y will cancel out when added. So you will be left with only x terms

( 2x - y = 13x ) × 2

+ -3x + 2y = -18

________________

2(2x) - 3x + 2(-y) + 2y = 2(13x) - 18

4x - 3x - 2y + 2y = 26x - 18

x + 0 = 26x - 18

x = 26x - 18

________________

[Then use the properties of equality to simplify the expressions in the equation to derive the value of x]

x - x = 26x - 18 - x (subtraction property of equality)

0 = 25x - 18

0 + 18 = 25x - 18 + 18 (addition property of equality)

18 = 25x

18 / 25 = 25x / 25 (division property of equality)

18 / 25 = x

x = 18 / 25 (symmetric property of equality)

_______________

Now with the value of x, we can find the value of y by substituting the value of x into the variables of the top equation {2x – y = 13x} because this involves the simpliest steps.

Given x = 18 / 25.

2x – y = 13x → 2x – y + y = 13x + y → 2x = 13x + y → 2x – 13x = 13x + y – 13x → -11x = y → y = -11x.

Now that we know y = -11x, y = -11(18/25) which is - (11 × 18) / 25 = -198/25

Answer:

35 mph

Step-by-step explanation:

The answer should be the average speed it takes to drive, so you would find the average of the speed to go to A with the speed to go to B. You already have the two answers for part A and B, so you would add them, then divide them by 2. It would look like this:

[tex]\frac{30+40}{2} =\frac{70}{2} =35[/tex]

So it would be 35 mph

Answer:

30% profit

Step-by-step explanation:

The amount by which the shopkeeper reduced the advertised selling price = 20%

The resulting profit over the cost price = 4%

Let x represent the initial advertised selling price, and let y represent the new selling price, and let c represent the cost price, we have;

x - 20% of x = y

x - x × 20/100 = y

0.8·x = y

y = c + 4% of c = 1.04·c

∴ 0.8·x = 1.04·c

x = 1.04·c/0.8 = 1.3·c

x = 1.3·c = c + 0.3·c = c + 30% of c

x = c + 30% of c

From which we have that the initial advertised selling price, x = The cost price + 30% of the  cost price

Therefore, the initial advertised selling price = The cost price + 30%profit on   cost price.

The shopkeeper would have made 30% profit if the dress had then been sold at the original selling price.

Answer:

5

Step-by-step explanation

2 + 5 is 7 which equals 1 person 7 x 5 = 35 which means their will be 5 people per group because 30 {room cost} plus 35 is 65

what do i mean?

2 + 5 IS 1 person and 2 plus 5 is 7 so the remaining money they have would be 35 because 65 minus 30 is 35 so i divid 35 by 7 which brings 5 people

s=3

Answer:s=3

Step-by-step explanation:

So the first thing that you do is the distributive property on both sides and then you combine like terms. After that you put the variable all on on side consonants. Then you divide and you get s.
