Answer:
Expression = -23 + 26i
Step-by-step explanation:
Given the following data;
x = -5 + 6i
y = 3 - 2i
Expression = 4x - y
Substituting the values of "x" and "y" into the equation, we have
4(-5 + 6i) - (3 - 2i)
Expanding the bracket, we have;
Expression = -20 + 24i - 3 + 2i
Expression = -23 + 26i
Answer:
9 4/9 (this is a mixed fraction btw)
Step-by-step explanation:
Question: 3 4/9 + 5 7/9
Add whole numbers:
3+5 = 8
Combine fractions: 4/9 + 7/9 = 13/9
*fix your improper fraction into a proper one*
so, 13/9 turned into mixed fraction is 1 4/9 (to be clear it's not 14, 1 is the whole number and then the fraction 4/9.) *write it like a mixed fraction please*
anyway, we're not done yet..
8+1 4/9
= 9 4/9
Answer:
20
Step-by-step explanation:
We have, 70% × x = 14
or,
70
/100 × x = 14
Multiplying both sides by 100 and dividing both sides by 70,
we have x = 14 × 100
/70
x = 20
If you are using a calculator, simply enter 14×100÷70, which will give you the answer.
