If in standard form you mean slope intercept form, then you are looking to create an equation that looks like this:
y = mx + b
So you need to move around the numbers whilst keeping both sides equivalent.
3x - 9 = 7y
7y = 3x - 9
y = (3x)/7 - 9/7
Your answer should look like this:
y = (3x)/7 - 9/7
If this is not what you meant by standard form please comment and I will see if I can adjust the answer.
Answer:
x = 7.2
Step-by-step explanation:
a² + b² = c²
x² + (19.2/2)² = (24/2)²
x² + 9.6² = 12²
Subtract 9.6² from both sides
x² = 12² - 9.6²
x² = 51.84
x = 7.2
The equation is y=1x-2

Maya is cleaning out her closet and is shocked when she realizes that she has 55 shirts. She decides to donate 40% of them. How many more shirts does she have for her ?
Answer:
The number of T-shirt that Maya will have after donating 40% is 22 shirts
Explanation:
Given:( as per the above data provided)
Total number of T-shirts = 55
Percentage of T-shirts she wish to donate = 40%
To find:
Remaining number of T-shirt left after donating?
Formula to be used:
Remaining T shirt = (Total number of T-shirt /100) X The Percentage of T-shirt she wish to donate
Steps:
Substituting all the above provided values in the formula we get,
= (55/100)*40
= 22 shirts.
Thus the number of T-shirts left with her is 22.
The answer is 90
20%of 99=18
