Well, I actually did the entire calculations until I figured out that its very simple, and I didn't need to!
If she has already saved 6%, then to find how much she still needs to save, we subtract 100% from 6%.
So Nina still has to save 94% of the total cost to get the bike.
Formulating a system of equations, we have:
x+y=-6 Equation 1
x-y=12 Equation 2
Solving the system of equations, we have:
y = -6 - x (Subtracting x from both sides of the Equation 1)
x - (-6 - x)=12 (Replacing y=-6-x in the Equation 2)
x + 6 + x = 12 (Using the sign rules)
2x + 6 = 12 (Adding like terms)
2x = 6 (Subtracting 6 from both sides of the Equation)
x=3 (Dividing on both sides by 2)
Replacing x=3 in y=-6-x , we have:
y = -6 - 3
y= -9
Given that the numbers are 3 and -9, the smallest of them is -9.
The answer is -9.
When the corner is cut to a dimension of x, then the flap folded up, its height will be x. The appropriate choice is the last one, ...
(25 -2x)(20 -2x)x
C + b = 72......because the is a total of 72 cans and bottles
1c + 2b = 92.....because each can is worth $ 1 and each bottle is worth $ 2....c is the number of cans and b is the number of bottles...and she collected $ 92
so ur system is :
c + b = 72
1c + 2b = 92
Answer:
1 gallon
Step-by-step explanation:
Since the relationship is direct, meaning as the number of square feet decreases, the number of gallons also decreases.
3:900 = x:300
solution:
3(300) = 900x
900=900x
x=1
