Answer:
x = 14
Step-by-step explanation:
7x - 27 = 3x + 29
Subtract 3x from both sides;
4x - 27 = 29
Add 27 to both sides;
4x = 56
Divide both sides by 4;
x = 14

Answer:
cm.
Step-by-step explanation:
We have been given that the average human body cell is about 
cm in diameter. The diameter of a plant cell is 
cm.
To find the combined diameter of the body cell and plant cell, we will add both diameters.
First of all let us convert our given diameters in standard notation.
Let us convert our answer in scientific notation.
Therefore, the combined diameter of the body cell and plant cell is cm.
Answer:
0 7
1 7.20
2 7.40
3 7.60
Step-by-step explanation:
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
