So basically you are trying to find X×13.6=34 and you have to solve for X. To find the answer divide 13.6 from both sides of the equation to leave X by it self. You should get 2.5 as the answer.
(Bc)/(ab)=tan1
(Ef)/(ec)=tan2
Angle 1= angle 2
Tan1=tan2
(Bc)/(ab)=(ef)/(ec)

Answer:
$17,000 at 14% and $9,000 at 2%
Step-by-step explanation:
Let x = amount invested at 14%.
Let y = amount invested at 2%.
x + y = 26000
0.14x + 0.02y = 2560
-0.02x - 0.02y = -520
(+) 0.14x + 0.02y = 2560
-------------------------------------
0.12x = 2040
x = 17,000
x + y = 26000
17000 + y = 26000
y = 9000
Answer: $17,000 at 14% and $9,000 at 2%
Answer:
T = $19.50 + $0.25(m - 200)
Step-by-step explanation:
Using the information provided we can create the following equation. This equation subtracts 200 from the total number of minutes and multiplies this by the cost per minute. Then it adds the fixed cost for the initial 200 minutes to get the total of the bill (T).
T = $19.50 + $0.25(m - 200)
Now that we have the equation we can plug-in you total for last month's bill and solve for m to calculate how many minutes you used last month.
$29.50 = $19.50 + $0.25(m - 200) ... distribute 0.25
$29.50 = $19.50 + $0.25m - 50 ... combine like terms
$29.50 = $0.25m - $30.5 ... add 30.5 on both sides
$60 = $0.25m ... divide both sides by 0.25
240 = m
Finally, we can see that you used a total of 240 minutes last month.
Answer:
$30
Step-by-step explanation:
since there is no sales tax,
Amount of money used to pay
= change + total price of items bought
Let's find the total price of the items she bought.
<u>Chicken</u>
1 package ----- $12.36
2 packages ----- 2($12.36)= $24.72
<u>Broccoli</u>
1 pound ----- $1.98
½ pound ----- $1.98 ÷2= $0.99
<u>Milk</u>
1 gallon ----- $3.49
Total amount paid
= $24.72 +$0.99 +$3.49
= $29.20
Thus, amount of money Susan used to pay
= $29.20 +$0.80
= $30
