Answer:
x : y = 9 : 13
Step-by-step explanation:
Given that
3x - y : x + 2y = 2 : 5
Express the ratio in fractional form, that is
= 
( cross- multiply )
5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )
15x - 5y = 2x + 4y ( subtract 2x from both sides )
13x - 5y = 4y ( add 5y to both sides )
13x = 9y ( divide both sides by 13 )
x = 
y ( divide both sides by y )
= , that is
x : y = 9 : 13
2x+3-5.32=68.82
2x= 71.14
x=35.57
each sneaker costs $35.57
X=16
Divide 44 by 11 you get 4
Same with 52 and 13
Multiply 4 and 4
Answer:
that answer is 7 is bigger then 1.9
Step-by-step explanation:
so 7 is a whole and 1.9 is a decimal
Here we can simplify the product by multiply the square root 2 with square root 2 first.
=3*2
=6
So answer is 6
