Answer: -15a - 27
Step-by-step explanation:
McKenna made her first mistake in Step 2. You would need to multiply -5 by 3a and 6, not add it to 3 first.
The correct steps would be:
3−5(3a+6)
3+(−5)(3a+6) Step 1
3 - 15a - 30 Step 2
-15a - 27 Step 3
Answer:I = PRT
PRT = I
R = I/PT
R = 3224/(8060)(5)
R= 8%

this maybe the answer sorry if it isn’t
The complete question is as follows.
The equation a = can be used to determine the area , <em>a</em>, of a trapezoid with height , h, and base lengths, and . Which are equivalent equations?
(a)
(b)
(c) =
(d)
(e) = h
Answer: (a) ; (d) ;
Step-by-step explanation: To determine :
a =
2a = ()h
To determine h:
a =
2a =
= h
To determine
a =
2a =
Checking the alternatives, you have that and = h, so alternatives <u>A</u> and <u>D</u> are correct.
This is important because if you were to answer in complex fractions instead of its simplest form, you would have a tough time multiplying complex fractions together. You would get a HUGE denominator or numerator, which makes things difficult. It is important to write a fraction in its simplest form because of exactly that; making things simple. Would you rather multiply 64/132*64/132 or 1/2*1/2?
Answer:
No Ms Chen is not correct and the price is $1.99 per pound
Step-by-step explanation:
Ms Chen is not correct because she did the division wrong. She was supposed to divide the price by the pounds but she divided the pounds by the price. The correct way of doing this would be dividing $12.95 by 6.5 which gets you 1.99230769 but since this is money that rounds to $1.99 per pound
