Explanation:
The given equation are,
In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,
Subtract 0.8 from both the sides.
Add 0.4y on both the sides.
So, after aligned the system of equation have two equations.
Both equation are show in third option, So third option is correct.
Answer: 40 sit ups
Step-by-step explanation:
50+70+80+80+40+60+40= 420 ÷ 7 = 60
Answer:
2 years 5 months
Step-by-step explanation:
TO solve, convert everything to months
1 year has 12 months, so 5 years would have 60, because we multiply by 5.
Then we add the remaining 2 months, 60+2 =62
Then we can convert 2 years to 24 months. Then we add the remaining 9 months to get 24+9, 33
Then we subtract the 2, and get 62-33= 29, and we divide by 12 to convert to years and months. 29 divided by 12 is 2 and 5 months
so your answer is 2 years and 5 months
