Equate real part and imaginary part:
LHS:
real part -- 12
imaginary part -- 5y
RHS:
real part = 4x
imaginary part = 25
Equating::
12 = 4x
x = 12/4
x = 3
Again:
5y = 25
y = 25/5
y = 5
So,
x = 3
y = 5
Answer:
x=18
Step-by-step explanation:
set up the equation:
DBC+DBC=ABC
79+79=(9x-4)
Simplify both sides of the equation.
79+79=9x−4
79+79=9x+−4
(79+79)=9x−4(Combine Like Terms)
158=9x−4
158=9x−4
Flip the equation.
9x−4=158
Add 4 to both sides.
9x−4+4=158+4
9x=162
Divide both sides by 9.
9x
/9 = 162
/9
x=18
Answer:
22.50
Step-by-step explanation:
if one mile is 1.50 then just do 1.50*14 which gives you 22.50
Answer:
Step-by-step explanation:
6¼ ft - 8¾ ft = -2½ ft
(-2½ ft)/(1⅔ min) = (5/2 ft)/(5/3 min)
= (5/2)/(5/3) ft/min
= (5/2 × 3/5 ft)/min
= 1.5 ft /min
