Answer:

5y

Step-by-step explanation:

The reason it is 5y is because for every week, Diana buys 5 sodas which means you would have to multiply. For example, if you wanted to find how many sodas Diana drank in 7 weeks you would multiply 5(7) to get 35 sodas in 7 weeks.

Find the quotient of these complex numbers.
stich3 [128]

9514 1404 393

Answer:

  C.  (45+11i)/29

Step-by-step explanation:

Multiply numerator and denominator by the conjugate of the denominator.

  \dfrac{5-7i}{2-5i}=\dfrac{(5-7i)(2+5i)}{(2-5i)(2+5i)}=\dfrac{(5)(2)+(-7i)(5i) +(5)(5i)+(-7i)(2)}{2^2+5^2}\\\\=\dfrac{(10+35)+(24-14)i}{29}=\boxed{\dfrac{45}{29}+\dfrac{11}{29}i}

Answer:

Perimeter of Triangle: 6x+15

x=12.5

Step-by-step explanation:

The perimeter is the sum of all of the sides of the triangle.

Hence, the perimeter =3x+3x+15=6x+15

Since the perimeter is 90, 6x+15=90.

Subtract 15 from both sides:

6x+15-15=90-15

6x=75

Divide both sides by 6:

\frac{6x}{6}=\frac{75}{6}

x=12.5
