Answer:
first one 5/8
Step-by-step explanation:
2 1/2 / 4 = 5/8
First question:
1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)
Second question:
1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
78 units squared add together 27.5+12+22+16.5 and you’ll get your answer for triangles it’s 1/2bh and for the rectangles it’s just bh. hope this helped!
1/216 is the simplest, but <span>0.00462962962 is more precise.</span>
(6t-4) + (6t-4) + (6t-4) + (6t-4)
4(6t-4)
24t-16
