Answer: A
Step-by-step explanation:
<em>- and - = + </em>
-8 (4 - x) = 16
-32 + 8x = 16
8x = 16 + 32
8x = 48
x = 6
Answer: The system of equations represents the constraints in this situation are:
s + h = 40
$18s + $14h = $700
The above equations are known as simultaneous equations. 40 scarves and hats were sold, this can be represented with this equation:
number of hats sold + number of scarves sold = 40
s + h = 40
The total amount made from the sales is the sum of the total amount made from the sale of the hats and the total amount made from the sale of the scarves. This can be represented with this equation:
($18 x s) + ($14 x h) = $700
Step-by-step explanation:
Answer:
10 and 15
Step-by-step explanation:
let Cairo's age be x then Poppy's age is x + 5 , then
x + x + 5 = 25
2x + 5 = 25 ( subtract 5 from both sides )
2x = 20 ( divide both sides by 2 )
x = 10
That is Cairo is 10 years old and Poppy is 15
The appropriate price is
(150 ft)*(($0.15/in)*(12 in/ft)) = $270.00
Apparently, the factor (12 in/ft) was left out of the computation, so the charge was for $0.15 per foot.
a) The price was not correct. The correct price was $270.00
b) The mistake was charging by the foot rather than by the inch.
Divide total length by length of each piece to get the number of pieces.
= 30 ÷ 2/3
multiply by reciprocal of 2/3
= 30 * 3/2
= 90/2
= 45
ANSWER: Total number of pieces that can be cut is 45.
Hope this helps! :)
