12+a-4.2
Because sum is adding
And less than is subtracting
195 miles
45x4=180
45 divided by 3=15
180+15=195

Define length and width
---------------------------------------------------------------------------------
Let the width be x
Width = x
Length = 3x
---------------------------------------------------------------------------------
Form equation and solve for x
---------------------------------------------------------------------------------
x(3x) = 48
3x² = 48
x² = 48 ÷ 3
x² = 16
x = √16
x = 4
---------------------------------------------------------------------------------
Find length and width
---------------------------------------------------------------------------------
Width = x = 4
Length = 3x = 3(4) = 12
---------------------------------------------------------------------------------
Answer: Width = 4cm, Length = 12cm

Answer:
$35.7
Step-by-step explanation:
you can convert 15% to a decimal by dividing by 100.
15/100 = .15
if you multiply the decimal by the cost of the shirt you get how much the discount is.
0.15 * $42 = 6.30
so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.
$42 - $6.30 = $35.70 that is the sale price of the shirt.
