The ratio of boys to girls in hometown is 2: 3. if there are 8 boys, how many girls are there?

If the radio boys to girls is 2:3 you can solve the problem with equivalent fractions: 2/3 = 8/x , to be equivalent you have to multiply the numerator and denominator by the same number, which for this case has to be 4. The answer is: if there are 8 boys , there are 12 girls

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
