Answer:the answer is c
Step-by-step explanation:
Answer:
30 ml of 45% salt solution and 20 ml of 30% salt solution.
Step-by-step explanation:
Let x be the amount of 45% salt solution and y be the amount of 30% salt solution
the two equation will be:
x+y=60 -- A
0.45x+0.3y=0.4(60) -- B
Solve by substitution
Rewrite Equation A
x+y=60
x=60-y --- C
Substitute C into B
0.45(60-y)+0.3y=24
27-0.45y+0.3y=24
-0.15y=-3
y=20
<u>Substitute</u> the y=20 into equation C
x=60-20
x=30
Therefore, there was 30 ml of 45% salt solution and 20 ml of 30% salt solution.
3(3^8) this is how you write it as power. however if you simplify it will be 19683 ft
<span>Alex wants to borrow $1,000. The local bank says "10% Interest". So to borrow the $1,000 for 1 year will cost:$1,000 × 10% = $100</span>
In this case the "Interest" is $100, and the "Interest Rate" is 10% (but people often say "10% Interest" without saying "Rate")
Of course, Alex will have to pay back the original $1,000 after one year, so this is what happens:
Alex Borrows $1,000, but has to pay back $1,100<span>This is the idea of Interest ... paying for the use of the money</span>
I think it would be 10x+y because the slope is the amount he spends each month for the streaming service so then it would be 10x because x represent the number of months and then it’s +y because that’s the amount he already spent on the tablet
