For problems like this you can move the y's on the bottem up top by fliping the sign of the exponent (in this case 7 to -7) and MULTIPLYING it with EVERYTHING on top, then because of properties of multplication you can add the exponents to combine them into one term (in this case add 3 and -7 to get -4) $\frac{ y^{3} }{y^{7}}=y^3 *y^{-7} = y^{3+-7}=y^{3-7}=y^-4$ If any of this does not make sense let me know and ill try to clarify better

Answer:

Both Jeff and Lori are wrong.

Step-by-step explanation:

$3 - \frac{(4 \times 3)^{2} }{2} + (1 \times 6)$

$3 - \frac{12^{2}}{2} + 6$

$3 - \frac{144}{2} + 6$

$3 - 72 + 6$

$- 72 + 9$

$- 63$

-63 is the final answer

12.21 is 3.7 times the number p.

ASHA 777 [7]

P3.7 = 12.21 (p × 3.7 = 12.21)

p÷3.7 = 12.21÷3.7 (p÷3.7 cancels out p×3.7 and leaves you left with the equation p = 12.21÷3.7)

p=3.3

Step-by-step explanation: Pemdas

According to Khan Academy, "The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)."
