Answer:
Step-by-step explanation:
27+36
=9×3+9×4
=9(3+4)
=9×7
=63
27+36=63
so 27+36=9(3+4)
Answer:
11/3 divided by 2/3 = 5.5 or 11/2
Step-by-step explanation:
Answer:
Linear
Step-by-step explanation:
This is the answer because the water flows into the tank at a consistent rate.
Solving for y, we add 5y to both sides and subtract 4, getting 9x-4=5y. Dividing both sides by 5, we get 9x/5-4/5=y. Since the slope is 9/5 (since 9/5*x=9x/5), we multiply it by -1 and find the reciprocal of it to get -5/9 as the perpendicular slope, so -5x/9+b=y. Plugging 1 in for x and -6 in for y, we get -5*1/9+b=-6 and by adding 5/9 to both sides we get -5-4/9=b , and since in y=mx+b y and x are variables, we end up with y=-5x/9+(-5-4/9) for slope intercept form.
To get it into standard form, we need it in ay+cx=b with a, b, and c being constants. Adding 5x/9 to both sides, we end up with y+5x/9=(-5-4/9) for standard form
