Answer:

alan = 2 = 2x = 16

becky = 3 = 3x = 24

charlie = 4 = 4x = 32

Step-by-step explanation:

add 2 3 4 =

72 ÷ 9 = 8

alan = 2 = 2x = 16

becky = 3 = 3x = 24

charlie = 4 = 4x = 32

In a recent international sport competition, the top 3 countries— Country A, Country B, and Country C— won a total of 134 medals

vlada-n [284]

Answer:

Country A = 85, Country B = 29, Country C = 20

Step-by-step explanation:

A+B+C=134 ----- eq(1)

B=C+9 ------------ eq(2)

A=36+B+C ------ eq(3)

By substituting eq(2) in eq(3), we get:

A=36+C+9+C

A=2C+45 ------- eq(4)

Now substituting eq(2) & eq(4) in eq(1), we get

2C+45+C+9+C=134

4C+54=134

4C=134-54

4C=80

C=20

Now putting the value of C in eq(2),

B=20+9

B=29

Substituting the value of B & C in eq(1), we get:

A+29+20=134

A+49=134

A=134-49

A=85

What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−3, 1)?

puteri [66]

Answer: The answer is (D) $y-1=\dfrac{3}{2}(x+3).$

Step-by-step explanation: We are given to find the equation of a line which is parallel to the line in the graph and passing through the point (-3, 1).

The points (-2, -4) and (2, 2) lie on the line in the graph, so its slope will be

$m=\dfrac{2+4}{2+2}=\dfrac{6}{4}=\dfrac{3}{2}.$

The slope of the line parallel to the line in the graph will also be same. Since the new line passes through the point (-3, 1), so the equation of the line will be

$y=1=m(x+3)\\\\\Rightarrow y-1=\dfrac{3}{2}(x+3),$

which is in the slope-intercept form.

Thus, the correct option is (D).
