Answer:
x= 35000
y= 19000
Step-by-step explanation:
The investment in this question divided into two parts, first who earns 5.5% interest(X) and second who have 4% interest (Y).
The total interest gained is $2685 so you can get this equation.
0.055 x + 0.04 y = 2685
Both x and y sum is $54,000 so you can get this equation
x + y = 54,000
y=54000- x
If you combine both equations
0.055 x + 0.04 y = 2685
0.055 x + 0.04 (54000- x) = 2685
0.055 x + 2160- 0.04x = 2685
0.015x= 2685- 2160
0.015x= 525
x=35000
y=54000- x
y= 54000-35000
y=19000
Answer:
In the centre of a triangle
Step-by-step explanation:
The answer is D .64 I used a
A. 4x + 9 = 34
<u> - 9 - 9</u>
<u>4x</u> = <u>25</u>
4 4
x = 6.25
B. (x - 4)(x + 2) = 0
x - 4 = 0 U x + 2 = 0
<u> + 4 + 4</u> <u> - 2 - 2</u>
x = 4 x = -2
C. 2x² - 6x + 4 = 0
2(x²) - 2(3x) + 2(2) = 0
<u>2(x² - 3x + 2)</u> = <u>0</u>
2 2
x² - 3x + 2 = 0
x = <u>-(-3) +/- √((-3)² - 4(1)(2))</u>
2(1)
x = <u>3 +/- √(9 - 8)</u>
2
x = <u>3 +/- √(1)
</u> 2<u>
</u> x =<u> 3 +/- 1
</u> 2
x = <u>3 + 1</u> U x = <u>3 - 1</u>
2 2
x = <u>4</u> x = <u>2</u>
2 2
x = 2 x = 1
