<span>2/3 + y - 4/5 = 1/3
y = 1/3 - 2/3 + 4/5
y = -1/3 + 4/5
y =-5/15 + 12/15
y = 7/15</span>
Answer:
the perimeter of rectangle is 52cm if two adjacent sides are (2×+3)cm and (×+5)cm
108 sodas, you subtract the 30 from the 138 and thus 108.
You should use the ratio so
2/ 4 = 6.5 / n
n= 6.5 x 4 / 2 = 13 inches
2- for two hours ------> four inches of snow
for x hours -----> y inches of snow
the equation is
2/4 = x/ y
x= 2y / 4
for x is the hours and y is the inches
exercice 2
5 gr granula ----------------------> 1750 calories
2 gr granula ----------------------> n ?? calories
by cross multiplication
n = 2 x1750 / 5 = 700 calories .
2-
she wants to eat 175 calories so
u put granula under granula and calories under calories to make this cross
<span>5 gr granula ----------------------> 1750 calories
