<u>Geometry</u>

  • Complementary Angles - Angles that add up to 90°

Step-by-step explanation:

<u>Step 1: Set Up Equation</u>

<em>The 2 angles must add up to 90°.</em>

(8m + 4)° + 38° = 90°

<u>Step 2: Solve for </u><em><u>m</u></em>

  1. Combine like terms:                    8m + 42 = 90
  2. Isolate <em>m</em> term:                             8m = 48
  3. Isolate <em>m</em>:                                      m = 6

The 2 equations are 
-2x + y = -17 ---1)
3x + y = 23 ---2)
we need to have the same coefficient for one of the variables.
Already y variable has the coefficient of 1 for both equations so we can use the equations  as it is. 
2) - 1) subtract 1) from 2)
3x-(-2x) + y -y = 23-(-17)
5x = 40
x = 8
substituting x = 8 in the 2nd equation 
3*8 + y = 23
24 + y = 23
y = -1

solution - (8,-1)

pickupchik [31]

Answer: 1902.36

Step-by-step explanation:

When interest is compounded monthly , the formula to find the accumulated amount is

A=P(1+\dfrac{r}{12})^{12t} , where P = principal value , r = rate of interest , t = time.

As per given,

r= 24% =  0.24

P= $1500

t= 1 year

Put all value in formula , we get

A= 1500(1+\dfrac{0.24}{12})^{12\times 1}\\\\=1500(1+0.02)^{12}\\\\=1500(1.02)^{12}\\\\=1500(1.26824179456)\approx1902.36

Hence, he need to pay $1902.36.
