Answer:
12 students
Step-by-step explanation:
First, find the percentage of how many students have siblings:
3/10 = 0.3 = 30%
40 * 0.3 = 12
This means that 30% of this class are 12 students. These 12 students have siblings.

Answer:
$1200
Step-by-step explanation:
78 = 6.5%
This means that if you divide 78 by 6.5, you get the equivalent of 1% of the price:
78 ÷ 6.5 = 12
So 1% = 12
Now simply multiply this by 100 to get the full answer:
12 x 100 = 1200
So the camera cost $1200!

C
6x^2-13X-5=0
(3X+1)(2X-5)
3x-1=0
X=1/3. 2x-5=0. X= 5/2
You have to start within the parenthesis. To subtract fractions you need a common denominator. You'll get (3/4 - 2/4) Subtract them (1/4)and square both the top and bottom. (1/16) After that multiply by the 4. The number next to the parenthesis.(4/16 = 1/4) After that you add 5/4 to 1/4 and you'll get 6/4 which reduces to 3/2. That is the answer
Take 12500-11625, which is 875.
Divide 875 by the original price, 12500, to get 0.07.
Multiply 0.07 by 100.
Your answer should be a 7% reduction.
