Standard form of a linear equation is Ax + By = C, where A, B, C are constants.
So,
y-8 = 3(x+1)
y-8 = 3x + 3
substract 3 from both sides,
y-8-3 = 3x+3-3
y-11 = 3x
substract y from both sides,
y-y-11 = 3x-y
-11 = 3x-y
So, the standard form is 3x-y = -11
First, convert the percent into a decimal. You can make any percent into a decimal by moving the % sign two places to the left and making it into a decimal point.
70% = 0.70
In mathematics, if can also mean multiply.
0.70 * 50 = 35
So, 35 is the answer to this question.
The system of equation is: 15x+12y=348, 8x+8y=200. The price of a jacket times number of jackets means the amount of money spent on jackets, and same for sweatpants. Their sum is the total amount of money spent.
