1 + 1x
OR
1 + x
They mean the same thing! Hope this helps!
It is possible to have an isoceles triangle with on 80 degree angle because all sides to a triangle add to 180 degrees so if you minus 180-80=100. There is 3 sides to a triangle so half the 100 and you get 50 which means you get two of the same angles which are 50 degrees. That means that the question is possible and is isoceles.
2.8 miles.
My Work/Reasoning:
First we find the rate. 7/60 mpm (miles per minutes)
Then we multiply that by 24. 7/60 * 24
Finally, we solve the equation and learn that Chang would run 2.8 miles in 24 minutes.
Answer:
$13.60 in change
Step-by-step explanation:
2.5 lbs x $1.00 = $2.50 for pears
1.3 lbs x $3.00 = $3.90 for apples
$2.50 + $3.90 = $6.40 paid total
$20.00 - $6.40 = $13.60 change
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
