U should know the area of rectangle is w*l
if we increase it by double or times 2 its area will be
A=2w*2wl
A=4wl
area would be 4 times of original one
Now u can get the answer
The original price times the off price to get how much is the discount
3.25*0.25=0.8125
Subtract the discount from the original price
3.25-0.8125=2.4375=2.44
Or
3.25*0.75=2.4375=2.44
Answer:
it would be 5600
Step-by-step explanation:
you just find the % of it
The expression inside the absolute value can be either positive or negative.
above, they solved for x in the positive expression. x/2 + 3 = 2
solve for x in the negative expression.
x/2 + 3 = -2
x/2 = -2 - 3
x/2 = -5
x = -10
4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
