It is 121 x 10^12 so the answer is A.
Answer:
286/20 or 14.3
Step-by-step explanation:
According to the Question,
- Given, Joey exercising every day. Today he jogged for 8.40 minutes and sprinted for 0.65 minutes then jumped roped for 10.30 minutes and stretched for 5.25 minutes .
jogged for 8.40 minutes = 8minute + 0.40minute ⇒ (8 + 4/10) ⇒ (8 + 2/5) Minutes.
- sprinted for 0.65 minutes = 65/100 ⇒ (13/20)Minutes.
- stretched for 5.25 minutes = 5 + 25/100 ⇒ (5 + 1/4)Minutes.
- Total numbers of minutes that joey spent exercising = (5 + 1/4)Minutes + (13/20)Minutes. + (8 + 2/5) Minutes.
⇒13 + 1/4 + 2/5 + 13/20
⇒13 + (5+2*4+13)/20
⇒13 + 26/20
⇒286/20 or 14.3 or 14 minutes 3/10 minute .

Answer:
(-1, 0)
I will solve your system by substitution.
(You can also solve this system by elimination.)
2x+y=−2;−3x+2y=3
Step: Solve2x+y=−2for y:
2x+y+−2x=−2+−2x(Add -2x to both sides)
y=−2x−2
Step: Substitute−2x−2foryin−3x+2y=3:
−3x+2y=3
−3x+2(−2x−2)=3
−7x−4=3(Simplify both sides of the equation)
−7x−4+4=3+4(Add 4 to both sides)
−7x=7
−7x
−7
=
7
−7
(Divide both sides by -7)
x=−1
Step: Substitute−1forxiny=−2x−2:
y=−2x−2
y=(−2)(−1)−2
y=0(Simplify both sides of the equation)
