Answer:
4:5
Step-by-step explanation:
If there are 12 boys and 15 girls, the ratio of boys to girls will be 12:15.
However, this can be simplified by dividing each number by 3. This can be done since both 12 and 15 are divisible by 3.
12:15
= 4:5
So, the ratio of boys to girls in Timara's class is 4:5
Answer:
x=-1
Step-by-step explanation:
<em>Add by 1 from both sides of equation.</em>
<em>9x-1+1=-11+1</em>
<em>Simplify.</em>
<em>-11+1=-10</em>
<em>9x=-10</em>
<em>Divide by 9 from both sides of equation.</em>
<em>9x/9=-10/9</em>
<em>Simplify, to find the answer.</em>
<em>x=-10/9</em>
<em>x=-1 is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>
