Answer:
let z=3-i
|z|=square root 10 r=square root 10
Ø=-pi/6
z=sqr 10 × e^i×pi/6
z=sqr 10(cos(-pi/6) +isin(-pi/6))
If the expression is 2*x*3, x must be 1/3 in order to cancel out the 3 which would leave the 2.
Answer: x < 36

Answer: hot dog = $1.75
<u>Step-by-step explanation:</u>
Let h represent hot dogs and c represent bags of chips.
Customer 1: 4h + 2c = 9.00 → 3(4h + 2c = 9.00) → 12h + 6c = 27.00
Customer 2: 5h + 3c = 11.75 → -2(5h + 3c = 11.75) → <u>-10h - 6c </u>= <u>-23.50</u>
2h = 3.50
<u> ÷2 </u> <u> ÷2 </u>
h = 1.75
Answer:
Step-by-step explanation:
I think this question is not clear.
If you could explain/upload the centimeter grid it'd be explain.
But generally, what you should do is: calculate the number of centimeters on the longer side (length (l)) and note that, now calculate the number of centimeters on the shorter side (breadth(b)).
Use the formula, Area of a rectangle = l×b to solve your math problem
