Answer:
First estimate:
63% is kind of close to 60%
41 is kind of close to 40
its easy to compute 60% of 40 - it's 24
Second estimate:
14% is close to 15%
96 is close to 100
15% of 100 = 15
The factors are (a - 2) and (6a + 5) .
If the expression is equal to zero, then 'a' can be 2, and 'a' can be -5/6 .
Answer:
2 1/3
Step-by-step explanation:
Answer:
<h3> ∠R = 69</h3>
Step-by-step explanation:
<h2>Angle sum property</h2>
Sum of all angles of triangle = 180
5x - 11 + 3x - 3 + 3x + 18 = 180
5x + 3x + 3x -11 - 3 + 18 = 180
Combine like terms
11x + 4 = 180
11x = 180 - 4
11x = 176
x = 176/11
x = 16
∠R = 5x - 11
= 5*16 - 11
= 80 - 11
= 69
Answer:
1. $450
2. $128
Step-by-step explanation:
1. new price = .4 (.4 * original price x)
72 = .16x
x = 450
2. new price = .75 (.75 * original price x)
72 = .5625x
x = 128
