Answer:
Its a i just took the test
Step-by-step explanation:
Z + Y = a right angle so need to equal 90 degrees:
Find Z & Y:
2b + 6 + 3b -1 = 90
5b +5 = 90
5b = 85
b = 85/5
b = 17
Z = 2(17) +6 = 34+6 = 40 degrees
Y = 3(17) - 1 = 51 - 1 = 50 degrees
Y & W make a straight line so need to equal 180:
W = 180 - 50 = 130 degrees.
Z & X make a straight line so need to equal 180:
X = 180 - 40 = 140 degree.

Answer:
a)$ 324,000
ii) 2.5%
x=2, y=1
Step-by-step explanation:
(a)Simple interest is calculated by the formula
<em />
<em></em>
<em> I= Interest received</em>
<em>P=Principal</em>
<em>r= interest rate (per year)</em>
<em>t=time (in years)</em>
<em />
<em>I= ($900,000)(12)(3%)</em>
<em>I=$324,000</em>
<em />
(ii)From the formula above, we find r
<em>r=2.5%</em>
<em />
<em>_______________________________</em>
<em>3x+y=7</em>
<em>2x-2y=2</em>
<em />
<em>Let's take 2x-2y=2</em>
we divide by 2 both sides and we get
<em>x-y = 1</em>
so <em>x = 1+y</em>
and replace it in the other formula:
<em />
<em>3(1+y) + y = 7</em>
<em>3+3y+y = 7</em>
<em>3 + 4y = 7</em>
<em>4y = 7-3</em>
<em>4y= 4</em>
<em>y = 1</em>
<em>x = 1+y</em>
<em>x = 1+1</em>
<em>x = 2</em>
