12 more boys than girls
ratio of boys to girls = 7:5
thus 2/12 is difference between boys and girls = 12
total students = 12 ÷ 2/12 = 72
Answer:
x=1
Step-by-step explanation:
multiply both sides by 28 (it is the Least Common Multiple) which would bring your equation to be
7x-2= 4x+1
3x=3
x=1
Answer:
i think its The sale price of the jeans is 50% of the original price.
Step-by-step explanation:


To solve for the area of a triangle, we multiply the length and height, then divide that by two. L = 10. H = 7.



To solve for the perimeter, or edges, of the triangle, we need to use the Pythagorean Theorem: a² + b² = c² to solve for the third side. We already know two measures: 10 and 7. Now we need to square them, add them together to get c², then take the root of that number.

We cannot simplify √149, so we either leave it, or round it.

This is rounded to the nearest 10,000.

Now that we have the measure of the longest side, we can add all three sides together to get the perimeter of the triangle.
