You add all of it up and divide by how many numbers are.... so the answer would be D- 56
1. -4x > -16...divide by -4 and change inequality sign
x < -16/-4
x < 4
2. -y/2 < 6 ...multiply both sides by 2
-y < 12 ...multiply both sides by -1 and change inequality sign
y > -12
3. -5a < -20....divide both sides by -5 and change inequality sign
a > -20/-5
a > 4
4. -b/2 > -1....multiply both sides by 2
-b > -2...multiply both sides by -1 and change inequality sign
b < 2
5. -4b < 24....divide both sides by -4 and change inequality sign
b > -24/4
b > - 6
6. -7c < -14....divide both sides by -7 and change inequality sign
c > -14/-7
c > 2
7. -d/3 > -9...multiply both sides by 3
-d > -27...multiply both sides by -1 and change inequality sign
d < 27
Here are the areas of the 3 separate shapes:
1. 27.5 m^2
2. 25.5 m^2
3. 27.5 m^2
As you can see, the 1st and 3rd shapes share the same total area, so those are the shapes you should select.
To divide by a fraction, multiply by the reciprocal of that fraction.
1/3 • 5/1 or 1/3 • 5
Calculate the product straight across.
1/3 • 5/1 = 5/3
Answer:
The part that is shaded is 5/14
Step-by-step explanation:
The total circle is 1
1/2 + 1/7 + x = 1 where x is the shaded area
Multiply each side by 14 to get rid of the fractions
14(1/2 + 1/7 + x) = 1*14
7 + 2 + 14x = 14
9+14x = 14
Subtract 9 from each side
14x = 5
Divide by 14
x = 5/14
The part that is shaded is 5/14
