Answer:
The answer should be -3/2 I believe
Step-by-step explanation:
Formula I used: (x1-y1)/(x2-y2) = x/y (fraction) then simplify if possible
ex: (1 - 4)/(-4 - -6) = -3/2, cannot simplify so that is your answer
Answer: 18.125 lbs
Explanation: The baby weighed 18.125 pounds at the end of eight months.
The baby weighed 7.25 lbs at birth. Eight months later, he weighed 2.5 or 2½ times its birth weight. Multiply 7.25 by 2.5 (which equals 18.125).
So now eight months later, he's 18.125 pounds.
Answer:
The product rule for exponents states that to multiply powers with the same base add their exponents. The term “powers” refers to numbers written in exponential form, such as 3^4. “Base” refers to the number that is being raised to the power, and it appears directly to the left of exponent. For instance, in 3^4, the 3 is the base, and the 4 is the exponent, or power.
