T us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
= 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
= 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3
The answer to 7 x 9 is 49
Answer:
Work backwards
Luis is 62 inches tall
maria is 1/3 taller than luis ( 62 + 1/3)
Maria is 62 1/3
Juan is 1 and 1/4 shorter than maria ( 62 1/3 - 1 1/4)
Answer: 61 1/12
Step-by-step explanation:
Answer:
x+y+3 or 1x+1y+3
Step-by-step explanation:
3/4x+1/4x+1y+3
3/4x+1/4x=1x
1x+1y+3
You can't do x+y+3 so it stays x+y+3. Hope this helps.
