Answer:
a= 5
Step-by-step explanation:
3 (a-7)= 14-4a -Remove Parentheses
3a-21=14-4a -Move the terms
3a+4a=14+21 -Collect like terms
7a=35 -Divide both sides
a=5 - Solution
9514 1404 393
Answer:
$109.38
Step-by-step explanation:
The time worked was ...
(12:00 -8:00) +(17:30 -12:45) = 4:00 + 4:45 = 8:45 . . . . hours:minutes
This is 8 45/60 hours = 8 3/4 hours = 8.75 hours.
The pay for 8.75 hours is ...
8.75 × $12.50 = $109.375 ≈ $109.38
X=2+5y
x-y=30
basically, all you're doing here is solving a system of equations. use the second equation to find out what x or y means. i'm going to solve it for x.
this is the new equation : x=30+y
now i plug this equation into the first one.
30+y=2+5y
30=2+5y-y
30=2+4y
28=4y
y=7
now that you know what y is, take that second equation we did in the beginning and plug in y.
x-7=30
solve for x
x=37
the two integers are 37 and 7.
Step-by-step explanation:
you have to add all of the together so like graph number 1 add all those numbers together and then divide by how much numbers there are and that is the median
3.5 kg:800g
3500g:800g
35g:8g
