Answer:
140.42 US dollars
Step-by-step explanation:
250x1.3687=342.175
342.175-150=192.175
192.175/1.3687=~140.41
<u>D. 85 ((: </u>
40 + 55 = 95 then you would do 180 - 95 = 85
all triangle equal 180 ((:
Answer:
Step-by-step explanation:
1 × a = a
a² = a*a ; a³ = a*a*a .....
<em>(1).</em>
(a). 
(b). 
= 
(c). 
<em>(2).</em>
(e). 
= 
= 
(f). 
= 
× = 
<em>(3).</em>
x² = 30² + 16² = 900 + 256 = 1156 = 34² ⇒ <em>x = 34 units</em>
(x+5) represents each side of a square. Since all sides of a square are equal, we know that all sides are (x+5).
Base x height = (x+5)(x+5)
Which is x^2+10x+25!
Answer:
y - x = - 2 b
Step-by-step explanation:
Given-
3 x + 2 y = 5 a + b...................(i)
4 x - 3 y = a + 7 b.....................(ii)
<em><u>Multiply by 3 and 2 in equation (i) & (ii) respectively-</u></em>
<em><u>Add equation (iii) & (iv)-</u></em>
9 x + 6 y = 15 a + 3 a...................(iii)
<u>8 x - 6 y = 2 a + 14 b</u> ...................(iv)
17 x = 17 a + 17 b
<u>x = a + b</u>
Put x = a + b in equation (i)-
<em>2 y = 5 a + b - 3 a - 3 b</em>
<em>2 y = 2 a - 2 b</em>
<u>y = a - b </u>
<em>∴ y - x = a - b - ( a + b )</em>
<em>y - x = a - b - a - b</em>
y - x = - 2 b
