well, first of all, you can try it out with numbers like 4,6,28...
3(4)
=12
3(6)
=18
3(28)
=84
also, you can disprove the other theories
a) 0+3=3 (odd)
b) 4^2-1=15 (odd)
Cancel equal terms on both sides of inequality
7-3x < 13
move constant to the right side and change its sign
-3x<13-7
subtract the numbers
-3x<6
divide both sides of inequality by -3 and flip the inequality sign
answer is: x>-2
Answer: 4.5×10^9
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
10
. The sign of the exponent will depend on the direction you are moving the decimal.
4.5
×10
9
12
Step-by-step explanation:
porque 3 +3 +2+ 1 +1 +1 +1=13
We know that
A quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary. ( Inscribed Quadrilateral Theorem)
so
m∠B+m∠D=180°
2x+(3x-5)=180
5x=180+5
5x=185
x=185/5
x=37°
m∠A=x+5-----> 37+5------> 42°
the answer is
m∠A is 42°
