He must sell $200 worth of electronics.
200 x .5( 5%) = 100.
We have two unknowns from the equation therefore, two equations are needed. These equations are:
<span>
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
</span>3x + –4x +10<span>= 9
</span><span>x = 1
We substitute the value of x to either of the equations and solve for y.
</span>y = –4(1) +<span>10
</span><span>y = 6

Answer:3rd option
Step-by-step explanation:
tan(R) = 7/4
Thus, the angle measure of R is the inverse tan of 7/4, or the 3rd option. Just define what tan(R) is, and then solve.
I think its 7. i know its late but im taking it now. myself
