Wxy is an isosceles triangle with line wx congruent to line wy. if wx is 3 more than four times x, xy is 7 less than five times x, and wy is 66 less than seven times x, find x and the measure of each side.

x=10

Step-by-step explanation:

part 1:

4x+3=5x-7

(subtract 4x from 5x to get 1x and add 7 to 3 to get 10)

1x=10

x=10

part 2:

WX=4(10)+3=43

XY=5(10)-7=43

WY=7(10)-66=4

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
