7/x = 5/y
Can be changed to:
5x = 7y
So, x = (7/5)y and
y = (5/7)x
Answer:
Step-by-step explanation:
3x² -2 =3*(-3)²-2=3*9 - 2
= 27 - 2
= 25
(y-60) = 56
Because opposite angles in a rhombus are congruent in a rhombus.
So,
y=16
Also in a rhombus all 4 sides are equal so you can set
16 = 3x + 4
So,
X= 4
Answer:
answer is 10
Step-by-step explanation:
2x^2(x-5) /10x
x=10
so,
=2*10^2 (10-5) / 10*10
=2*100(10-5) /100
=200*5 / 100
=1000/100
=10
Answer:16
Step-by-step explanation:
(4(10)+2(6)+3(2+2))/4=16
