Answer:

A.

Step-by-step explanation:

The triangles are similar, so we can estimate that the ratio between them is 1:2 (23.5/11.5~~2). Now we have that 44/2 is 22 and 44+22 is 66. The closest answer to 66 is 65.5, which is A.

Answer:

65.5 in

Step-by-step explanation:

Ok, the two triangles are similar, since they're both right triangles, the angle in C are congruent, and the third has to be by difference. It means that the distance DC is proportional to 44 inches, on the proportionx:44 = 11.5:23.5 \rightarrow x= 44\frac{11.5}{23.5} = 21,5 in To this we need to add the 44 inches traveled in the first part, to get a total of 65.5 in

A. <br> -3y − 2x = 5<br> B. <br> 3y − 2x = 5<br> C. <br> 3y − 2x = -5<br> D. <br> 3y + 2x = 5
Airida [17]

Answer:

C) 3y -2x= -5

Step-by-step explanation:

(1,1), (4,3)

slope= y2-y1/ x2-x1

slope= 3-1/4-1= 2/3

(4,1)

Substitute into y=mx+b

1= 4(2/3)+b

1= (8/3) +b

-5/3= b

3(y= 2/3x -5/3)

3y= 2x -5

3y -2x= -5

What and how do you get the answer to this problem? <br>y=ad-7;a
aleksklad [387]

Assuming you want to solve for a, then

ad - 7 = y (reversing the equation to have a on left side )

add 7 to both sides to isolate the term with a

ad = y + 7 ( divide both sides by d )

a = \frac{y + 7}{d}
