Answer:
x = -1
Step-by-step explanation:
1.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
2.1 Solve : -2 = 0
x = -1
Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
So I worked this out by adding all the houses together. I whole hour is two half hours. So it made it 2/3 of an hour. so I added everything together = 1/3+ 1/3+ 1/3 +1/3+ 1.5/3 = 3 1/2 Hours to walk.
Answer:
29/69 (= 0.42)
Step-by-step explanation:
there are several ways to do this, one way is to use fractions:
Expressing each decimal in improper fractions:
14.5 = 14 1/2 = 29/2
34.5 = 34 1/2 = 69/2
Hence,
14.5 ÷ 34.5
= 29/2 ÷ 69/2
= 29/2 x 2/69
= 29/69 (answer)
If you need the answer in decimal, you can use long division to do 29÷69 and you will get 0.42 (nearest hundredth)
