6.2 and 1/4
7.3²
8. 11/50
Find the percent of the number.
9. 20% of 90
10. 140% of 15
Find the whole.
11. 4% of what number is 2?
12. 125% of what number is 30

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

the ratio would be 4: 3, the four being for jackson, and the three being not for him.
