K= 8. If you look at the pattern each x value is multiplied by 8 to give you the y value. You could also solve it by:

40=k5
40/5=k
8=k

you could do this with any of the x or y values and still end up with 8.

15% of the students in Mrs. Madison’s math classes have an ‘A’. If 18 students have an ‘A’, how many students are in Mrs. Madiso

120 .
_________________________________
<span>Explanation:
_______________________________________________
15% of x = 18 ; x = total number of students.
_______________________________
Solve for: "x" ; which is our answer.
____________________________________

15 % of x = (15/100) * x = (0.15)x ;
_______________________________

(0.15) x = 18 ;

Divide each side by: "(0.15)" ; to isolate "x" on one side of the equation; and to solve for "x" , which is our answer:
_________________________________

</span>(0.15)x / (0.15) = 18 /(0.15) ;
_____________________________
x = 120 ; They are 120 students in Mrs. Madison's math classes.

The question asks to type the answer as a number. So:

120 .

A summer camp counselor wants to find a length x in feet across a lake as represented in the sketch to the left

Nata [24]

The question is incomplete and without a picture. I found similar question as follows:

A summer camp counselor wants to find a length, x, in feet, across a lake as represented in the sketch above. The lengths represented by AB, EB, BD and CD on the sketch were determined to be 1800 feet, 1400 feet, 700 feet, and 800 feet, respectively. Segments AC and DE intersect at B, and the angle AEB and the angle CBD have the same measure. What is the value of x?

Answer:

1600ft

Step-by-step explanation:

Angle AEB and CBD is the same value.

Referring to the picture, since ABC and DBE are straight lines and crosses each other at B, the angle DBC and EBA are equal.

Since we have 2 equal angle, the third angle must be the same as well.

Therefore we can conclude that both ABE and CBD are similar triangle but with different factor with;

AB similar to BC

EB similar to BD

AE similar to CD

To find the factor between ABE and CBD,

EB / BD = 1400 / 700 = 2
