Answer:
Number of rotations r < 5.25
Step-by-step explanation:
Given: bottom of the desktop is 74.5 cm from the floor.
Top of Ignacio's legs are 49.3 cm from the floor.
Each clockwise rotation on the knob raises Ignacio's legs by 4.8 cm.
To find: Inequality to determine the number of clockwise rotations r, Ignacio could make with the knob without his legs touching the desk.
Solution: Distance between Ignacio's legs and the base of the desktop = 74.5 -49.3 = 25.2
Therefore inequality will be
Height raised in one rotation × r < 25.2
4.8×r < 25.2
r < 25.2÷4.8
r < 5.25
Answer:
12. a = 2
13. 
Step-by-step explanation:
12.
6a(a + 3) = 2a(3a + 5) + 16
First, distribute 6a on the left side, and distribute 2a on the right side.
6a² + 18a = 6a² + 10a + 16
Subtract 6a² from both sides.
18a = 10a + 16
Subtract 10a from both sides.
8a = 16
Divide both sides by 8.
a = 2

The LCD of 2 and 3 is 6. We multiply both sides of the equation by 6 to get rid of all denominators.
Combine like terms on the left side. Distribute the 2 on the right side.
Subtract 2x from both sides.
Divide both sides by 3.

It's basic math.
Answer:
x= 70
Step-by-step explanation:
AB= 180 so u add 20+ 50 and then substract that to 180 which leaves you with 110. The angles are the same on both sides so the other angle is also 110, leaving x to be 70°
hope this is correct lol :)
The slope of the line should be 2 because when using rise over run for the graph it is shown that the slope rises 2 and runs 1 meaning the fraction is 2/1 which when simplified is 2
