X = Ishaan
y = Christopher
3y = x
x = y + 14 Put the first equation into the second.
3y = y + 14
2y = 14
y = 7
Christopher is 7
Ishaan is 21
My friend the answer is calculated by dividing denominator by 2 ie the answer is 1.
Answer:

Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces



Lastly, add the leftover to get the actual length of the wood

Substitute 50w for Result and 20 for Leftover

<em>Hence, the length of the wood is 50w + 20</em>
X is less than or equal to $30, she can spend $30, she cant spend more, she can spend less.
The answer should look like X<30 with a line under the less than sign, i hope this helps.
