You have to replace d woth 3 in formula
7d^2+10=7*(3)^2+10=7*9+10=63+10=73
d is the correct answer
Answer: Y= 2 X=1
Step-by-step explanation:
2x+y=4 4x+2y=8
2x =/2 2y= /2
y=2 4x=4
/4= /4
X= 1
13.1 an hour, 34 hours a week
13.1 x 34 = 445.4 a week
to find out how many weeks, divide 4300 and 445.4 which is 9.65 weeks, which is technically 10 weeks
it would take 10 weeks to earn 4300
To find the average: the sum of the values/number of values
=250+310+275+195/4
=257.5
