Answer: 15/4 or 3 3/4
Explanation: You make 2 1/2 into 5/2 (improper fraction) and 1 1/2 into 3/2.
You multiply the two together (5/2 x 3/2) equaling 15/4 (improper fraction) or 3 3/4 (mixed fraction)
Y2-y1/x2-x1. so -7-8/-1-(-1)= -15/1
Answer:
length : 10 yard
width: 14 yard
Step-by-step explanation:
Let l be the length of the yard.
Since the width is 6 yards less than twice its length, we can say the width is 2l-6.
With width x length=area,
l (2l -6) = 140
2l^2 - 6l = 140
2l^2 - 6l - 140 = 0
Using the quadratic formula,
we can determine l = 10 or -7
since the length should not be negative,
the length is 10 yard.
Now substitute l=10 into 2l-6.
width = 2(10)-6
= 14 yard
I would put d. 117 because 180-63= 117 and go by the opposite interior etc. rules.
Answer:
Answer: =2a + 16
Step-by-step explanation:
8+9−1+2a =8+9+−1+2a
now its time to to do CLT
=8+9+−1+2a
=(2a)+(8+9+−1)
=2a+16
