Answer:
$56.25
Step-by-step explanation:
3 Loaves or bread cost $1875
1 loaf costs $6.25
$6.25*9=$56.25
23. not equivalent because the first row 3x-9y=5 then if you multiplied this equation by 2 it will be 2(3x-9y) = 2(5) so 6x-18y= 10 not 6x-9y=10
24.equivalent because the second row 2y-6x=8 multiplied by 2 is 2(2y-6x)= 2(8) so 4y-12x=16
25. equivalent because the first row 5x+3y=19 multiplied by 2 is 2(5x+3y) = 2(19) SO 10X+6Y=38 and the second row 2x+4y=20 multiplied by 5 is 5(2x+4y)= 5(20) so 10x+20y=100
Hello!
To find the greatest common factor, you must find all the factors of both numbers and see which similar one is the greatest.
27: (1,27) (3,9)
36: (1,36) (2,18) (3,12) (4,9) (6,6)
As you can see the, the greatest common factor is 9.
I hope this helps!
Answer:
y = - 
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 7 when x = - 4, then
7 =
( multiply both sides by - 4 )
- 28 = k
y =
← equation of variation
When x = 5 , then
y =
= -
