Answer:
$3.13
Step-by-step explanation:
Get the price per oz:
5/16 = 0.3125
Multiply that by the amount of ozs you are looking to buy:
0.3125 x 10 = 3.125
Round to get your answer
(x-8)(x+5)
First thing you do is put the X's into the parentheticals because it is x^2 meaning there are 2 factors with x's. Then, you wonder what factors of -40 could add to get -3. In this case, they are -8 and 5. -8 times 5 is -40 and -8 +5 is -3. Then, you just add -8 and 5 beside the x's in the parentheticals.
Answer:
2x+14
Step-by-step explanation:
(3/4)x-7.3+(5/4)x+21.3
(3/4+5/4)x+21.3-7.3
2x+14
