Answer: -18=v
Step-by-step explanation: You subtract 8 from both sides. -10-8=-18 which will equal to v.
Answer:
width=18cm
Step-by-step explanation:
perimeter= 2(l+b)
90=2(27+b)
90/2=27+b
45-27=b
b=18cm
. Subtract 10x from both sides.
. Divide by 5 on both sides. x=20. So you would need to buy 20 movies.
y =-3x + x + 9
Find y when x = 2
Substitute the value of x= 2 into the equation
y = -3(2) + 2 + 9
y = - 6 + 2 + 9
y = -4 + 9
y = 5
The answer is 5
