Answer: -2
Step-by-step explanation: When your adding and subtracting positives and negatives, it helps to use a number line to visualise what's going on in the problem.
On a number line zero is in the middle. All numbers to the right of zero are positive and all numbers to the left of zero are negative.
So when your simplifying a problem like 3 + (-5), we start at zero and positive 3 takes us to the right. From there, -5 moves us 5 units back to the left and we end up -2. So 3 + (-5) simplifies to -2.
I have attached a number line along with my work
for this problem below.
The perimeter (IP) of a rectangle is
P = 2(length + width)
let width = w then length = w + 88
P = 2(w+w+88) = 2(2w+88) = 4w+176
Thus P = 4w+176 = 7272
hence 4w = 7272 - 176 = 7096
so w = 7096/4 = 1774
width = 1774 inches and length = w+88 = 1774+88 = 1862 inches
First year:
.3 x 2593 = 777.9
$2593 - $777.90 = $1815.10
Second year:
.3 x 1815.10 = 544.53
$1815.10 - $544.53 = $1270.57
Third year:
.3 x 1270.57 = <span>381.171
$1270.57 - $381.171 = $</span>889.39900
$889.39900 rounded to the nearest hundredth is $889.40
Rational ! the number doesn't repeat forever or anything like that. it simplifies nicely.
Answer:
The answer is D if you forgot the 3 between the = sign and the + sign
Step-by-step explanation:
I just did 12 x p + 3 = 99
You have to do this because 12 times the amount of jerseys ordered (p) plus the 3 dollars of extra shipping cost. That equals 99.
