What are numbers when Rs 880 is divided in to the ratio of 1 by 5 is to 1 by 6
Answer:
The ratio of 1 by 5 is to 1 by 6 is Rs 176 : Rs 146.67
Step-by-step explanation:
The given amount here = Rs 880
Now let us assume the 1 by 5 of Rs 880 = m
and assume 1 by 6 of the amount Rs 880 =n
To Find m : n
Now,
or, 1 by 5 = 176
Similarly:
or, 1 by 6 = 146.67
⇒ m : n = 176 : 146.67
Hence, the ratio of 1 by 5 is to 1 by 6 = Rs 176 : Rs 146.67

Answer:
Both the equations would work
Step-by-step explanation:
If you want to see if both the equations would work, just try plugging in numbers. If you plug in 5, the first equation would give you 10 and the second equation would give you 10 too. This would be the same for every number. This shows that they were both right and both the equations are the same. All Aisha did was distribute the 2 onto both variables in the parenthesis.
3x-2y=19
Y=x-7
Answer:
x = 5 and y = -2
Step-by-step explanation:
Here you have given what y is equal to, this means you can sub this into the first equation:
3x - 2(x - 7) = 19
Expand the brackets:
-2 * x = -2x
-2 * -7 = 14
3x -2x +14 = 19
Move the +14 over to the other side making it a -14:
3x - 2x = 19 - 14
3x - 2x = 5
3x - 2x = x
So x = 5
Now sub this into the first equation:
3(5) - 2y = 19
15 - 2y = 19
Move the -2y over to the other side making it a +2y, and move the +19 over to the other side making it a -19:
15 - 19 = 2y
-4 = 2y
Divide both sides by two:
y = -2
So x = 5 and y = -2
