$7 is 1/6 of 3/7 of Bella's money, so she had $98 to start with. 4/7 of 98 is $56, as you figured.

The dictionary and the books cost 56

d+3b = 56

3/8 d = 1/2 * 3b

so, 3d = 12b

4b + 3b = 56

b = 8

check:

3 books cost 24

dictionary cost 32

3/8(32) = 1/2(24)

12=12

Jay works as a waiter at a restaurant.
ryzh [129]

Answer:

67.33.

Step-by-step explanation:

To figure out the tip, you need to find 20% of $52.60.

0.2×52.6=10.52

You should leave $10.52 for the waiter if you want to leave him exactly 20%.

To figure the tax, you need to find 8% of $52.60.

0.08×52.6=4.208

Next, add them up:

52.6+10.52+4.208=67.328

The total bill, including tax and tip, will be $67.33.

J has coordinates (-2,8) R has coordinates (-7,-3) find the coordinates of point A that partition (JR) in the ratio 5:2 and sket
kolbaska11 [484]

J Coordinates: (-2,8)

R Coordinates: (-7,-3)

A cuts JR in the ratio of 5:2

We have to find out the coordinates for A. Let coordinates of A be (x,y)

The section formula helps us determine a point (x,y) that divides the line joining two points (x1,y1) and (x2,y2) in the ratio of m:n

x1, y1 represents the point which is more on the left side of the x axis, while x2,y2 represents the point which is more on the right side of the x axis

So here x1 = -7, y1 = -3, x2 = -2, y2 = 8, m = 5, n = 2

As per section formula, x = (mx₂ + nx₁) / (m + n), and y = (my ₂ + ny₁) / (m + n))

⇒ x = ((5*-2) + (2*-7)) / (7)

⇒ x = (-10+ (-14)) / (7)

⇒ x = -24 / 7

⇒ x = -3.43

and y = ((5*8) + (2*-3)) / (7)

⇒ y = (40 - 6) / 7

⇒ y = 4.86

So coordinates of A are (-3.43,4.86)

Please see the attached image for seeing the points and line on chart.
