<h3>
Answer: 410 mL </h3>
=====================================================
Explanation:
The ratio of A to B is 5:3
Multiply both parts by x to get 5x:3x
We need 5x parts of A and 3x parts of B
Adding those parts should get us 656 mL total
A+B = total
5x+3x = 656
8x = 656
x = 656/8
x = 82
Therefore, we need 5x = 5*82 = 410 mL of compound A
Also, we need 3x = 3*82 = 246 mL of compound B
In total, we have A+B = 410+246 = 656 mL which helps confirm the answer.
-----------
Side note: The ratio 410:246 reduces to 5:3 after dividing both parts by 82.

Answer:
$875.39
Step-by-step explanation:
1) Divide the tax rate (6.500%) by 100 to get a decimal rate of 0.06500.
2) Multiply the purchase price ($821.95) by the 0.06500 to get a sales tax amount of $53.43.
3) Add the $53.43 sales tax to the $821.95 price to get a total of $875.38.
4) Round $875.38
-4
Because 15x-7x= 8x
8x+5x= 13x
13x= -52
-52 / 13= -4
x = -4
Answer:
24X58-9=1,383
800x24=19,200
Step-by-step explanation:
24x58=(24x8)+(24x50)
24x8=160+32=192
24x50=200+1,000=1,200
192+1,200=1,392-9=1,383
800x24=3,200+16,000=19,200
