Answer:
Estimated answer = 57.0
Exact answer = 54.04
Step-by-step explanation:
Since 19.3 is lesser than 19.5, it will be rounded down to 19.0
Since 2.8 is greater than 2.5, it will be rounded up to 3.0
<u>Estimated multiplication</u>
19.0 * 3.0 = 57.0
<u>Actual multiplication</u>
19.3 * 2.8 = 54.04
1) Divide both sides by 2
2x+12^2/3 =16
2) Solve the exponent
2x+12^2/3 =16
(2x+12^2/) ^3/2 =16^3/2 ( raise both sides to power)
2x+12 = 64
3) Subtract 12 from both sides
2x + 12 - 12 = 64-12
2x = 52
4) divide both sides by 2
2x/2 = 52/2
x = 26
Final answer : x = 26
Answer:
60
Step-by-step explanation:
All angles = 180
All sides are equal
Therefore, 180/3 = angle degrees = 60
x is an opposite angle of bottom right angle therfore x = 60
A) Table D does not represent a function as y can't have two different values for the same value of x.
B) Table A and C.
