Answer:
x =30
Step-by-step explanation:
in order to evaluate the solution 4/5=20/(x-5)?
solution
the first step to take is to cross multiply
4/5=20/(x-5)
we have,
5 x 20 = 4 ( x -5)
100 = 4x - 20
combine the like terms
100+20 = 4x
120 = 4x
divide both sides by the coefficient of x
120/4 = 4x/4
30 = x
x =30
therefore the value of x in the expression 4/5=20/(x-5)? is 30
10x8? 80. 10, 20, 30, 40, 50, 60, 70, 80
Jo's lunch contains the most calories because if its twice breakfast and breakfast is 450 multiply that X2 you get 950. Then add 950 plus 450 you get 1400 then subtract 1400 from 2200 then you get the remaining 800 calories which shows that the most calories she eats is in her lunch meal.
