Answer:
Part A) Multiply by 16
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
Your function is split into 4 parts.
We want to use the piece that includes x=6.
This only included in the inequality that says x is greater than or equal to 5. Since that is, we use the expression that corresponds to that to find f(6).
f(6)=2(6)-6
f(6)=12-6
f(6)=6
Answer:
17 quarters, 37 nickels
Step-by-step explanation:
We just have to set up a system of equations
quarters are x
and nickels are y
x+y=54
0.25x+0.05y=6.10
now we can get ready to substitute
x=54-y
substitute it in
0.25(54-y)+0.05y=6.10
simplify/evaluate
13.5-0.25y+0.05y=6.10
-0.2y=-7.4
y=37
plug it back in
x+37=54
x=17
Answer:
$4.20
Step-by-step explanation:
y = .05x (using stat on calculator)
y = .05(84)
$4.20
3 2/5 + 4 1/5
3 + 4 = 7
2/5 + 1/5 = 3/5
The answer is 7 3/5
Hope this helps!
