Step-by-step explanation:
the ratio of postcard Rapheal to Carlene's was 8 to 5. On Friday both acquired twice as many postcards. Later that week Carlene counted their new numbers of the postcards that she had sixty less postcards than Raphael.How many postcard did Rapheal have first.
To expand you must first distribute (multiply) the 2 to the numbers inside the parentheses
2(x - 5)
(2 * x) + (2 * (-5) )
2x + (-10)
2x - 10
There are no like terms, therefore (x - 5)2 expanded is 2x - 10
Hope this helped!

Answer:
$4.84
Step-by-step explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
Answer:
Volume = 18 cm^3
Surface Area = 58 cm^2
Step-by-step explanation:
Find the volume with the formula V=w*h*l
W= width
H = height
L = length
W= 2cm
H= 1 cm
L= 9 cm
V= w*h*l
V= 2cm * 1 cm * 9cm
V= 18 cm^3
Find the surface area with the formula A= 2(w*l + h*l + h* w)
W= width
H = height
L = length
W= 2cm
H= 1 cm
L= 9 cm
A= 2(w*l + h*l + h* w)
A= 2(2cm*9cm + 1cm*9cm + 1cm* 2cm)
A= 2(29cm)
A= 58cm^2
