<h2>Answer: So you do 18/75 = x/100</h2><h2>then you cross multiply so 75 times X = 75x and 18 times 100 = 1800</h2><h2>Then you put 75x = 1800 and divide them both and you will get 24</h2><h2>So, X = 24</h2><h2 /><h2 /><h2>If I'm incorrect, then correct me please.</h2>

Y=1/4x−2y=−2x+3 help solve problem.
8_murik_8 [283]

Answer:

  (x, y) = (2 2/9, -1 4/9)

Step-by-step explanation:

Equate the values of y and solve for x.

  1/4x -2 = -2x +3

  (2 1/4)x = 5 . . . . . . . . add 2+2x to both sides

  x = 20/9 = 2 2/9 . . . multiply by 4/9

  y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation

  y = -1 4/9

The solution is x = 2 2/9, y = -1 4/9.

\boxed {Children = \frac{Boys+Girls}{2}} (for the average)

Substitute the values mentioned in the question.

10.54 = (10.35 + Girls)/2

21.08 = 10.35 + Girls

Girls = 10.73 years

Wilson is 6 years older than Mary. Wilson's age is 10 years less than five times Mary's age. The equations below model the relat
Neko [114]

Answer:

Wilson is 6 older than mary

w=6+m

wilson is 10 less than 5 times mary

w=-10+5m

w=5m-10

so now we set them eqal to each other since both equal w

m+6=w=5m-10

m+6=5m-10

minus m both sides

6=4m-10

add 10 to both sides

16=4m

divide both sides by 4

4=m

sub back

w=m+6

w=4+6

w=10

wilson=10

mary=4

the correct method is math
