Answer:

12:24 = 1:2

Step-by-step explanation:

Since there are 12 multiplication problems, and 24 division problems, the ratio of multiplication and division problems are 12:24, now we need to put it in simplest form.

We need to find the highest number of which both are divisible by, 12 and 24 are both divisible by 12.

So 12÷12 = 1, and 24÷12 = 2, so 12:24 in simplest form is 1/2 or 1:2.

Determine the value of a if one solution to the quadratic equation is x equals 5 + 3/2 I
Sindrei [870]

The value of a is \frac{-9}{4}

Step-by-step explanation:

<u>1. Determine the other solution of x</u>

If one value is 5 + \frac{3}{2} then the other value is 5 - \frac{3}{2}

<u>2. Use reverse technique to find the equation</u>

(5 + \frac{3}{2}) (5 - \frac{3}{2}) = 0

25 - \frac{-15}{2} + \frac{15}{2} - \frac{9x^{2} }{4} = 0

- \frac{9x^{2} }{4} + 25 = 0

<u>3. The equation is</u> - \frac{9x^{2} }{4} + 25 = 0

<u>4. Find the value of a</u>

a is the number with the variable x^{2} therefore it is - \frac{9}{4}
