Really easy seventh grade math can I get this problem answered? Thanks!!

Answers

Answer 1

Answer: 20/8=x/6
x=15
they are similar so the proportion is the same

Answer 2

Answer:

x = 15

since the figures are similar then the ratios of corresponding sides are equal

$(x)/(6)$ = $(20)/(8)$ ( cross- multiply )

8x = 6 × 20 = 120 ( divide both sides by 8 )

x = 15

Find the rate of change demonstrated in the graph below.

Answers

Answer:

Rate of change = $(9)/(2) = 4.5$ .

Step-by-step explanation:

Rate of change = $(y_2 - y_1)/(x_2 - x_1)$ .

Use the coordinates of two points on the graph. (Any point can be chosen. We will still arrive at the same rate of change).

Using (2, 9) and (4, 18),

Let,

$(2, 9) = (x_1, y_1)$

$(4, 18) = (x_2, y_2)$

Rate of change = $(18 - 9)/(4 - 2) = (9)/(2) = 4.5$ .

PLS HURRY use the graph to answer the question. Which table of ordered pairs shows a proportional relationship? x 1 12
y 2 6

x 5 12
y 10 6

x 5 8
y 10 4

x 3 5
y 6 10

Answers

Both lines on the graph show proportional relationships. You want to choose the table that has both of its points on the same line. That would be the 4th one:

... x 3 5

... y 6 10
