Answer:
15s
Step-by-step explanation:
Write like so:
54m = 9s
90m = x
Cross multiply:
(90*9)=(54x)
810 = 54x
Divide both sides by 54:
810/54 = 54x/54
15 seconds = x
Answer:
Yes, this is linear.
y = -4x
Step-by-step explanation:
12x = 7y - 10y
12x = -3y
-3y = 12x
/ -3 /-3
y = -4x + 0

Answer:
x=-10
Step-by-step explanation:
4.5(8-x)+36=102-2.5(3x+24) first you multiply 10 to both sides
4.5(8-x)x10+36x10=102x10-2.5(3x+24)x10
Then you have to refine the equation
45(8-x)+360=1020-25(3x+24)
Then you expand it
45(8-x)+360
=360-45x+360
Simplify
360-45x+360 -45x+720
Expand it one more time
-45x+720=-75x+420
Subtract 720 from each side
-45x+720-720=-75x+420-720
Simplify
-45x=-75x-300
Add 75x to both sides
-45x+75x=-75x-300+75x
Simplify
Divide both sides by 30
30x/30=-300/30
Then you get -10
The answer is 16.
Since the rectangles are similar, the ratio of their height and width will be the same
The width of rectangle B is 10, which is 2 x the width of rectangle A
So the length will also be 2 x the length of A
2 x 8 is 16
Answer:
32,768
Step-by-step explanation:
Remember to follow PEMDAS.
First, solve for the exponents for both terms:
Multiply the two terms together:
