Answer:

10= 19 - 11

Step-by-step explanation:

10+ 9= 19 and 7+12=19

10 is obviously equal to 10

10-4=6 and 3+3=6

But 10 is not equal to 19-11=8

Step-by-step explanation:

1) r^3r^3

\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}

=r^{3+3}

=r^6

2) 3k^3k^3

\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}

=3k^{3+3}

=3k^6

3) \left(3b^2\right)^3

\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n

=3^3\left(b^2\right)^3

=27\left(b^2\right)^3

=27b^6

4) \left(2m^3\right)^3

\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n

=2^3\left(m^3\right)^3

=8\left(m^3\right)^3

=8m^{3\cdot \:3}

=8m^9

5) \frac{3r^3}{r^2}

\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

=3r^{3-2}

=3r^1

=3r

I went to the store and bought 0.89 pounds of apples. Apples cost $1.39 a pound. How much did i pay for apples?
Elena L [17]
If you bought 0.89 pounds at $1.39 per pound, the total cost was
0.89 \times 1.39 = 1.24
You paid $1.24 for the apples

Please fill in the blanks:
kati45 [8]

Step-by-step explanation:

y = mx + b

Your equation is y = 3/5x, which means you're "missing" the B

Whichhhhh, just means you're starting at (0,0)

  • Now, m represents the slope. So your slope was given right off the bat, 3/5.
  • You start at (0,0) and you count up 3, and right 5. Or you could do down 3 and left 5
  • This gives you a line with a slope of 3/5

Hopefully my drawing kind of explains it better
