Answer:
$7,000
Step-by-step explanation:
Let x = the part of $16,000 that was lent at 8%.
Then 16,000 - x is the part that was lent at 16%.
The interest earned at 8% is 0.08x.
The interest earned at 16% is 0.16(16,000 - x).
The total interest earned is 0.08x + 0.16(16,000 - x).
The total interest earned was $2,000, so
0.08x + 0.16(16,000 - x) = 2000
Now we solve for x to find out the amount lent at 8%.
0.08x + 0.16(16,000 - x) = 2000
0.08x + 2560 - 0.16x = 2000
-0.08x + 2560 = 2000
-0.08x = -560
x = 7000
Answer: $7,000
a. 12 deg, b. 168 deg
We can create a systems of equations using this information, since supplement angles add up to 180 deg and complementary angles add up to 90 deg, when angle = x deg and supplement = y deg,
x + y = 180
y = 2(90 - x ) + 12
Solving:
x + 2(90 - x) + 12 = 180
-x + 180 + 12 = 180
x = 12
12 + y = 180
y = 168

</span>Joanna made a quilt using 72 squares
=> ¼ were green
=> 2/9 were blue
=> 4/9 were yellow
=> 1/12 were white
To get the value of this given fractions, it’s easiest to convert it into
decimals
=> green = 0.25 = 18
=> Blue = 0.22 = 15.8
=> yellow = 0.44 = 31.7
=> White = 0.083 = 5.98 or 6
Seeing on the decimal value, therefore white has the least number out of 4
colors.

Answer:
A= 115.625
Step-by-step explanation:
3,800x2-200=64A
Combine all like terms.
7,400=64A
Your going to have to divide 64 on bothe sides to leave 'A' alone one one side of the equal sign.
Your final answer will be <u>115.626=A</u>
