Answer:
3x-x+2=4
Step-by-step explanation:
Number of boys = x
Number of girls = x plus 15% of x = 1.15x
Ratio of boys to girls x:1.15x = 1:1.15 = 20:23
Answer:
30.5
Step-by-step explanation:
We know that ABCD is similar to EFGH so that means you can use a scale factor for them to figure out the rest of the side lengths.
25/12.5=2
12/6=2
Therefore the scale factor is two. Then we can use the numbers from the other side lengths which are 12 and divide by 2. Which gets you 6 for each remainder of the sides.
Then add them
12.5+6+6+6 = 30.5
P= 30.5
If you would like to solve the equation 3 * (4 * x + 2 * x) = 8, you can do this using the following steps:
3 * (4 * x + 2 * x) = 8
3 * 6 * x = 8
18 * x = 8 /18
x = 8/18
x = 4/9
The correct result would be 4/9.
