She paid $5.669. Rounded to the nearest hundredth, $5.67. Rounded to the nearest whole number, $6.
Answer:
$0.55
Step-by-step explanation:
1.5+4.50=6
1.75+4.80 =6.55
6-6.55=0.55
Answer:
3 apples and 7 bananas
Step-by-step explanation:
Let x=apple y=banana
1.75x+.7y=10.15
x+y=10
This is a systems of equation I that I will be using substitution to solve
x=10-y
We can plug this x value in for in the first equation
1.75(10-y)+.7y=10.15
17.5-1.75y+.7y=10.15
-1.05y= -7.35
y=7
This is our y value and we can plug this into any of the two first equations to get our x value
x+7=10
x=3
Which means he bought 3 apples and 7 bananas
Answer:
To find f(g(x)), we just substitute x = g(x) in the function f(x). For example, when f(x) = x2 and g(x) = 3x - 5, then f(g(x)) = f(3x - 5) = (3x - 5)2.
