A. 1/100 * x = 7
x = 7 * 100/1
x = 700
b. 50/100 * x = 33
x = 33 * 100/50
x = 66
c. 3/100 * 100 = 3
d. x/100 * 200 = 6
2x = 6
x = 3
e. 15/100 * 40 = 6

Answer:
angles 3, 1, 7, 5
Step-by-step explanation:
suplementary angles add up to 180 degrees so
<4 + <3=180
<4 + <1 =180
<4 + <7=180
<4 + <5= 180
Answer:
slope is 4/3x
Step-by-step explanation:
This looks complicated
lets simplify both sides
By multiplying top and bottom by the conjugate:-
left side = (5-3i)(x + iy) (4+5i) (5-3i)(x + iy) (4+5i)
------------------------ = ------------------------
(4-5i)(4+5i) 41
right side = (2 + i + 3-4)(2+i - 3 + 4i) (by Difference of 2 squares)
= 5-3i)(-1 + 4i)
so as left side = right side
(5-3i)(x+yi)(4+5i) = 41 (5-3i)(-1+5i)
5-3i is common so:-
(x + iy)(4+5i) = 41(-1+5i)
4x +5xi + 4yi - 5y = -41 + 205i
4x - 5y + (5x + 4y)i = -41 + 205i
EQuating coefficients we are left with the system of equations
4x - 5y = -41
5x + 4y = 205
solving this gives x = 21 and y = 25
