Answer:
$0.50 per pound
Step-by-step explanation:
To find cost per pound, divide cost by the corresponding number of pounds.
$3.50/(7 lb) = $0.50/lb
The unit rate for bananas is $0.50 per pound.
Hello from MrBillDoesMath!
Answer:
y = 2x + 2.5
Discussion:
2y -4x = 5 => add 4x to both sides
2y - 4x + 4x = 4x + 5 => -4x + 4x = 0
2y = 4x + 5 => divide both sides by 2
y = 2x + (5/2) => as 5/2 = 2.5
y = 2x + 2/5
Thank you,
MrB
The first thing to do is to clear t from both expressions and compare the value to verify if it is the same:
Expression 1:
sin t = .3
t = arcsin (0.3)
t = 0.3047
Expression 2:
cos t = .48
t = arccos (0.48)
t = 1.0701
Both expressions have a different value of t, therefore, both expressions do not satisfy the same number t.
answer:
It is not possible for the same value of t to be met: sin t = .3 and cos t = .48
