X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25
x + y = 47
25 + y = 47
y = 47 - 25
y = 22
ur numbers are 22 and 25
Answer:
650
Step-by-step explanation:
700-50=650
Multiply both sides of the second equation by 100 to get rid of the decimals:
0.05<em>n</em> + 0.10<em>d</em> = 1.50
==> 5<em>n</em> + 10<em>d</em> = 150
Multiply both sides of the first equation by -5:
<em>n</em> + <em>d</em> = 21
==> -5<em>n</em> - 5<em>d</em> = -105
Add the two equations together:
(5<em>n</em> + 10<em>d</em>) + (-5<em>n</em> - 5<em>d</em>) = 150 + (-105)
Notice that the terms containing <em>n</em> get eliminated and we can solve for <em>d</em> :
(5<em>n</em> - 5<em>n</em>) + (10<em>d</em> - 5<em>d</em>) = 150 - 105
5<em>d</em> = 45
<em>d</em> = 45/5 = 9
Plug this into either original equation to solve for <em>n</em>. Doing this with the first equation is easiest:
<em>n</em> + 9 = 21
<em>n</em> = 21 - 9 = 12
So Donna used 12 nickels and 9 dimes.
Answer:
6003
Step-by-step explanation:
Given : They harvested 5491 apples from one side of the McMillan farm.
They harvested 512 from the other side of the farm.
To Find : The total number of apples harvested at the McMillan.
Solution :
Since we know that
Number of apples harvested from one side of the McMillan farm = 5491
Number of apples harvested from other side of the McMillan farm = 512
Now we are supposed to calculate the total number of apples
So, we need to sum the number of apples of both the sides .
⇒5491+512
⇒6003
Hence , the number of apples harvested at the McMillan is 6003
Answer: (9,8)
Thats the answer
